(IPv6 SaaS) « ipSpace.net blog **[ipSpace.net Blog](https://daily.dev/sources/ipspace)** · 1 min read · 0 upvotes · 0 comments ## Summary Lasse Haugen launched whynoipv6.com, an 'IPv6 Shame-as-a-Service' site that documents major websites still lacking IPv6 connectivity. Notable offenders include twitter.com, azure.com, github.com, and even cloudflare.net — ironic given Cloudflare's role in providing IPv6 for others. The post and comments discuss real-world barriers to IPv6 adoption, including cases where enabling AAAA DNS records caused performance complaints due to broken IPv6 tunneling on customer networks, illustrating why many operators still avoid public-facing IPv6. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Which major websites still don't support IPv6? Sites documented as lacking IPv6 connectivity include twitter.com, azure.com, github.com, and notably cloudflare.net — despite Cloudflare being a provider that enables IPv6 for other websites. A public 'shame list' at whynoipv6.com tracks these. Conversely, Google, Facebook, Office.com, Netflix, Spotify, and Yandex are listed as 'heroes' that do support IPv6. _Teams evaluating IPv6 readiness across their stack track developments like these on daily.dev._ ## Similar posts on daily.dev - [IPv6 Adoption in 2026](https://daily.dev/posts/ipv6-adoption-in-2026-fi2iowjgj) · Lobsters · 1 upvotes · 0 comments - [I spent a WEEK without IPv4 to understand IPv6 transition mechanisms](https://daily.dev/posts/i-spent-a-week-without-ipv4-to-understand-ipv6-transition-mechanisms-iscykz0il) · Hacker News · 2 upvotes · 0 comments - [IPv6 in 2025 – Transitioning to IPv6](https://daily.dev/posts/ipv6-in-2025-transitioning-to-ipv6-x1lwgorkb) · Cisco · 0 upvotes · 0 comments - [UDP Broadcasting And The Brave New World Of IPv6](https://daily.dev/posts/udp-broadcasting-and-the-brave-new-world-of-ipv6-kbr2qsudb) · Hackaday · 0 upvotes · 0 comments --- Tags: [#infrastructure](https://daily.dev/tags/infrastructure), [#networking](https://daily.dev/tags/networking), [#dns](https://daily.dev/tags/dns) [View this post on daily.dev](https://daily.dev/posts/explore-why-no-ipv6-ipv6-saas-ipspace-net-blog-egauxywwh) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Explore: Why No IPv6?
