IPv4 addresses are decimal 32-bit addresses divided into four sections. Here\u2019s an example:<\/p>\n\n\n\n<p><strong>49.143.45.133<\/strong><\/p>\n\n\n\n<p>IPv4 addresses may not exactly trip off the tongue, but they\u2019re still relatively easy for humans to write down, type out, or remember. There\u2019s also support for over 4 billion different IPv4 addresses.<\/p>\n\n\n\n<p>The problem is, we now have more than 4 billion devices vying for these addresses! Internet service providers have had to utilize several workarounds that have stretched the system to its limit.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"IPv6\">IPv6<\/h3>\n\n\n\n<p>Enter IPv6. IPv6 is the replacement format for IP addresses first introduced in <a href=\"https:\/\/tools.ietf.org\/html\/rfc2460\" target=\"_blank\" rel=\"noreferrer noopener\">RFC 2460<\/a> on June 6, 2012. Instead of the 32-bit IPv4 notation, IPv6 is 128-bit. IPv6 is written in hexadecimal. Here\u2019s an example of a <a href=\"https:\/\/www.rapidseedbox.com\/vi\/blog\/what-is-ipv6\" target=\"_blank\" rel=\"noreferrer noopener\">full IPv6 address<\/a>:<\/p>\n\n\n\n<p><strong>0123:4567:89ab:cdef:0123:4567:89ab:cdef<\/strong><\/p>\n\n\n\n<p>IPv6 addresses can be shortened in many cases, but they\u2019re still a little harder to read for humans. But IPv6 has many advantages over IPv4, which we\u2019ll look at in the next section.<\/p>\n\n\n\n<div style=\"height:11px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"benefits-of-IPv6\">Benefits of IPv6<\/h2>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"IPv6 Addresses Explained | Cisco CCNA 200-301\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/irhS0ASkvy8?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p>IPv6 supports many more devices than IPv4. It solves the biggest problem we\u2019ve hit with IPv4, as it supports 340 undecillion devices, compared to IPv4\u2019s 4 billion. 340 undecillion IP addresses is equivalent to 340 trillion trillion trillion IP addresses.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"better-performance\">Better Performance<\/h3>\n\n\n\n<p>IPv6 has a simpler header format than IPv4. IPv4 uses 12 header fields, whereas IPv6 only uses 8 header fields. Additional information can be included in extension headers. Since typical routers don\u2019t need to process these extension headers, their job is made easier, so <strong>router performance improves<\/strong> with IPv6.<\/p>\n\n\n\n<p>IPv6 uses smaller routing tables and the source device now handles fragmentation rather than the router. Both improvements result in the <strong>more efficient and hierarchical routing of traffic<\/strong>.<\/p>\n\n\n\n<p>IPv6 has an integrated system for managing QoS (Quality of Service). QoS is apportioning specific amounts of available bandwidth to different applications sharing the network. While it\u2019s possible to do some QoS on IPv4 networks, it\u2019s baked into IPv6, with specialized fields like flow label and traffic class that ensure <strong>bandwidth is used effectively<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"stronger-security\">Stronger Security<\/h3>\n\n\n\n<p>The huge size of the address pool makes for <strong>better security<\/strong> by default, as it becomes much more difficult for hackers to brute-force scan through all the possible IP addresses on a network. Even better\u2014IPv6 automatically checks packet integrity and can encrypt traffic at a network level. This makes the use of IPv6 close to the security of using a VPN.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"simpler-network\">Simpler Network Infrastructure<\/h3>\n\n\n\n<p>Because the IPv4 protocol includes so few addresses, we\u2019ve long had to come up with ways to share IP addresses between computers.<\/p>\n\n\n\n<p>One way is through the use of NAT (Network Address Translation), where a router examines each packet entering the local network and decides which device it needs to be sent to. This has certainly extended the life of IPv4, but it slows things down as every packet entering the network needs to be examined and altered.<\/p>\n\n\n\n<p>IPv6 <strong>doesn\u2019t use require NAT at all<\/strong>. Not only is this more efficient, but it also makes setting up and maintaining company networks a lot easier.<\/p>\n\n\n\n<p>IPv6 also includes multicasting support by default. This is where <strong>a single packet can be sent to multiple devices concurrently<\/strong>. Though this is more of a niche use case, when it\u2019s required, using IPv6 for multicasting is much, much easier to set up than IPv4.<\/p>\n\n\n\n<div style=\"height:17px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"IPv4-vs-IPv6\">IPv4 vs IPv6 Proxies<\/h2>\n\n\n\n<p>When renting a proxy service for any of the types of applications listed above, you can now choose between <a href=\"https:\/\/www.rapidseedbox.com\/vi\/blog\/ipv6-vs-ipv4\" target=\"_blank\" rel=\"noreferrer noopener\">IPv4 and IPv6 proxies<\/a>.<\/p>\n\n\n\n<p>The table below provides a concise overview of the main differences between IPv4 and IPv6 proxies.

And because IPv6 proxies perform better with lower overhead, they cost less to run while delivering comparable or better performance.<\/p>\n\n\n\n<p>Consider an example spend $48 per month on proxies located in the United States.<\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table><thead><tr><th> <\/th><th>IPv4 Proxy<\/th><th>IPv6 Proxy<\/th><\/tr><\/thead><tbody><tr><td>Gi\u00e1<\/td><td>$48\/month<\/td><td>$48\/month<\/td><\/tr><tr><td>IP addresses<\/td><td>48<\/td><td>1000<\/td><\/tr><tr><td>IP thu\u1ed9c s\u1edf h\u1eefu t\u01b0 nh\u00e2n<\/td><td>C\u00f3<\/td><td>C\u00f3<\/td><\/tr><tr><td>Unlimited bandwidth<\/td><td>C\u00f3<\/td><td>C\u00f3<\/td><\/tr><tr><td>Price per IP address<\/td><td><strong>$1.00<\/strong><\/td><td><strong>$0.05<\/strong><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>While offering comparable features, <strong>IPv6 proxies are around 20 times cheaper than IPv4 proxies<\/strong> on a per-address basis.<\/p>\n\n\n\n<p>Not every application needs 1000 IP addresses, though.

IPv6 addresses are the clear winner here, as communication over IPv6 requires every endpoint to support <a href=\"https:\/\/learn.microsoft.com\/en-us\/previous-versions\/windows\/it-pro\/windows-server-2003\/cc776369(v=ws.10)?redirectedfrom=MSDN\" target=\"_blank\" rel=\"noreferrer noopener\">IPsec<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"clean-addresses\">Clean Addresses<\/h3>\n\n\n\n<p>IPv4 addresses being finite means they have a recordable history. Companies offering <a href=\"https:\/\/www.rapidseedbox.com\/vi\/proxy\" target=\"_blank\" rel=\"noreferrer noopener\">IPv4 proxies<\/a> are limited to a certain range of IP addresses, and when they are used over and over, third parties may add them to a list of known proxies and attempt to block them. This can reduce the efficiency of your application.<\/p>\n\n\n\n<p>Because IPv6 addresses are so ubiquitous, this type of proxy list blocking becomes much less effective. IPv6 addresses are often considered to be \u201cvirgin,\u201d \u201cclean,\u201d or previously unused, so your applications are much less likely to be detected or blocked.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"performance\">Performance<\/h3>\n\n\n\n<p>As outlined above, IPv6 offers better performance over IPv4, through improved routing, smaller headers, and better QoS support. Because IPv6 proxies perform better, they require fewer resources to run, so they cost less to rent.<\/p>\n\n\n\n<p>Depending on your application, you\u2019ll often get better results from an IPv6 proxy than an IPv4 proxy. This is especially the case if your application is likely to be blocked if it is detected. These improved results directly correlate with an improved return on investment.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"future-proofing\">Future Proofing<\/h3>\n\n\n\n<p>The ubiquitous implementation of IPv6 is inevitable and it\u2019s picking up speed. Using IPv6 for your proxy application means it will continue to work on IPv6 addresses across the internet, whereas restricting your use to IPv4 could have consequences in the future.<\/p>\n\n\n\n<p>The cost of IPv4 addresses should only continue to rise, too, as there is more and more pressure on the limited number of addresses we have now. Starting with IPv6 allows you to bypass this problem altogether.<\/p>\n\n\n\n<div style=\"height:11px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"reasons-IPv4\">Reasons to Choose an IPv4 Proxy<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"tried-and-true\">Tried-and-True<\/h3>\n\n\n\n<p>So, if IPv6 proxies offer so many advantages, why are IPv4 proxies still the norm? The most common reason is that IPv6 has only been around for a decade, whereas IPv4 has been around since close to the birth of the internet. IPv6, therefore, has more of an unknown quality to it, and many proxy users simply haven\u2019t heard of IPv6 or are unaware of its significant advantages.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"support\">Ubiquitous Support<\/h3>\n\n\n\n<p>One benefit of IPv4 proxies is the widespread support for IPv4. Virtually all new devices that will connect to the internet in some way have IPv6 support, with <a href=\"https:\/\/www.ferc.gov\/internet-protocol-version-6-ipv6-policy\" target=\"_blank\" rel=\"noreferrer noopener\">various laws<\/a> mandating its support.  It&#8217;s still in the minority, though.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.google.com\/intl\/en\/ipv6\/statistics.html#tab=ipv6-adoption\" target=\"_blank\" rel=\"noreferrer noopener\">Google shows<\/a> that over 40% of users now connect to its services using IPv6, and adoption is increasing at a linear rate. <a href=\"https:\/\/www.rapidseedbox.com\/vi\/blog\/ipv6-migration\" target=\"_blank\" rel=\"noreferrer noopener\">chuy\u1ec3n \u0111\u1ed5i sang IPv6<\/a> is continuing at a fair pace.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/IPv6-adoption-Google.jpg\"><img decoding=\"async\" loading=\"lazy\" width=\"992\" height=\"639\" src=\"https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/IPv6-adoption-Google.jpg\" alt=\"Graph showing slow uptake of IPv6 connected devices.\" class=\"wp-image-14045\" srcset=\"https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/IPv6-adoption-Google.jpg 992w, https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/IPv6-adoption-Google-300x193.jpg 300w, https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/IPv6-adoption-Google-18x12.jpg 18w\" sizes=\"(max-width: 992px) 100vw, 992px\" \/><\/a><figcaption class=\"wp-element-caption\">Image source: Google<\/figcaption><\/figure>\n\n\n\n<p>However, making such a fundamental change to how the internet works doesn\u2019t happen overnight. While IPv6 has been the de-facto option for over 10 years, many ISPs (internet service providers), companies, and organizations have a significant amount of older infrastructure that only supports IPv4. &nbsp;IPv6 is only used on <a href=\"https:\/\/w3techs.com\/technologies\/details\/ce-ipv6\" target=\"_blank\" rel=\"noreferrer noopener\">around 21.3%<\/a> of all websites.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><a href=\"https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/IPv6-for-website-w3techs.com_.jpg\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/IPv6-for-website-w3techs.com_.jpg\" alt=\"Graph showing slow increase in IPv6 usage on websites.\" class=\"wp-image-14046\" width=\"592\" height=\"392\" srcset=\"https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/IPv6-for-website-w3techs.com_.jpg 592w, https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/IPv6-for-website-w3techs.com_-300x199.jpg 300w, https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/IPv6-for-website-w3techs.com_-18x12.jpg 18w\" sizes=\"(max-width: 592px) 100vw, 592px\" \/><\/a><figcaption class=\"wp-element-caption\">Image source: Google<\/figcaption><\/figure>\n\n\n\n<p><a href=\"https:\/\/www.rapidseedbox.com\/blog\/ipv6-adoption-trends\" target=\"_blank\" rel=\"noreferrer noopener\">IPv6 adoption<\/a> varies quite significantly based on country, too. Whether this even matters to you depends on what you plan to use your proxy for. IPv4 proxies do have the advantage that they\u2019re definitely compatible with the majority of systems and protocols used online.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><a href=\"https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/IPv6-per-country-Google.jpg\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/IPv6-per-country-Google.jpg\" alt=\"Graph showing the per-country uptake of IPv6\" class=\"wp-image-14048\" width=\"934\" height=\"580\" srcset=\"https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/IPv6-per-country-Google.jpg 934w, https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/IPv6-per-country-Google-300x186.jpg 300w, https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/IPv6-per-country-Google-18x12.jpg 18w\" sizes=\"(max-width: 934px) 100vw, 934px\" \/><\/a><figcaption class=\"wp-element-caption\">Image source: Google<\/figcaption><\/figure>\n\n\n\n<div style=\"height:11px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Using IPv6 Proxies for Web Scraping and Automation<\/strong><\/h2>\n\n\n\n<p>One of the most powerful uses of an IPv6 proxy is large-scale web scraping and automation. The practical use cases can be: <\/p>\n\n\n\n<ul>\n<li>If you\u2019re collecting pricing data from online stores<\/li>\n\n\n\n<li>Monitoring SEO rankings<\/li>\n\n\n\n<li>Aggregating travel fares..<\/li>\n<\/ul>\n\n\n\n<p>Regardless, of your particular use case, <strong>an IPv6 proxy can give you access to clean IP addresses that rotate regularly. <\/strong>This rotation is essential for avoiding IP bans and reducing the number of CAPTCHA prompts you\u2019ll encounter.<\/p>\n\n\n\n<p>Because IPv6 addresses are abundant, you can maintain a large IP pool for a fraction of the cost of an equivalent IPv4 setup. This is ideal for automation workflows where hundreds or thousands of concurrent connections are needed. Clean, unused IPv6 addresses help ensure your requests blend in with normal traffic. This is perfect for improving success rates and keeping your operations running smoothly.<\/p>\n\n\n\n<p><strong>The image below shows automation routing traffic through multiple IPv6 proxies. It hides the scraper\u2019s IP and enables scalable, low-block web scraping.<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><a href=\"https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/IPv6-proxies.jpg\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/IPv6-proxies.jpg\" alt=\"automation routing traffic through multiple ipv6 proxies\" class=\"wp-image-37906\" width=\"557\" height=\"392\" srcset=\"https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/IPv6-proxies.jpg 855w, https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/IPv6-proxies-300x211.jpg 300w, https:\/\/www.rapidseedbox.com\/wp-content\/uploads\/IPv6-proxies-18x12.jpg 18w\" sizes=\"(max-width: 557px) 100vw, 557px\" \/><\/a><\/figure>\n\n\n\n<p>For developers, many IPv6 proxy providers offer API integration and SOCKS5 support, allowing for more granular control over session handling and location targeting. This makes them an ideal choice for automated scripts, bots, and data mining projects.<\/p>\n\n\n\n<div style=\"height:11px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Best Practices for Rotating IPv6 Proxies<\/strong><\/h2>\n\n\n\n<p>To get the most out of your IPv6 proxy pool, rotation needs to be handled intelligently. A well-managed rotation strategy keeps performance high, avoids unnecessary bans, and optimizes bandwidth usage.<\/p>\n\n\n\n<p><strong>Checklist for Healthy IPv6 Proxy Rotation:<\/strong><\/p>\n\n\n\n<ul>\n<li><strong>Distribute requests evenly<\/strong> \u2013 Avoid sending too many requests from the same IP address.<\/li>\n\n\n\n<li><strong>Control request pacing<\/strong> \u2013 Keep it under 2\u20133 requests per second per IP, adding small random delays.<\/li>\n\n\n\n<li><strong>Use sticky sessions when needed<\/strong> \u2013 Maintain the same IP for login sessions or multi-step scraping.<\/li>\n\n\n\n<li><strong>Rotate at smart intervals<\/strong> \u2013 Depending on the target site, a 30\u201360 second rotation interval works well.<\/li>\n\n\n\n<li><strong>Monitor proxy health<\/strong> \u2013 Regularly test IPs for connectivity, speed, and target compatibility.<\/li>\n\n\n\n<li><strong>Respect site rules<\/strong> \u2013 Following robots.txt and using secure connections helps maintain long-term access.<\/li>\n<\/ul>\n\n\n\n<p>By combining these practices with a large IPv6 pool, you can keep your scraping or automation setup efficient, cost-effective, and less likely to be detected.<\/p>\n\n\n\n<div style=\"height:12px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">FAQ: IPv6 Proxies<\/h2>\n\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1755283586658\"><strong class=\"schema-faq-question\">Can I use IPv6 proxies for all websites?<\/strong> <p class=\"schema-faq-answer\">Not all websites currently support IPv6.
