IPv6 Website Checker

Check if any website supports IPv6. Resolve AAAA records, verify dual-stack reachability and estimate IPv6 latency.

Uses public Google DoH (dns.google) to resolve A and AAAA records.

How it works

Find out if your target is IPv6-ready

Modern endpoints, IoT APIs and CDN edges are increasingly v6-only. We check resolution and reachability so you don't burn proxy budget guessing.

Step 1

DNS lookup

We resolve A and AAAA records via Google's public DoH so you see the same answers a fresh client would.

Step 2

Dual-stack check

We compare both record sets to flag IPv4-only, IPv6-only and properly dual-stacked domains.

Step 3

Latency estimate

We approximate IPv6 reachability latency so you know whether routing your scraper over v6 will hurt throughput.

Cheaper at scale

IPv6 pools cost a fraction of IPv4. If your targets accept v6, you can move to unlimited bandwidth pricing.

Dual-stack aware

Tells you whether to pin v6, pin v4 or let the resolver choose. Important for sticky session jobs.

Fresh data, no cache

Every check hits Google's public resolver, no stale answers from your local DNS or VPN.

如何检测网站是否支持 IPv6

这个 Rainproxy 免费工具用于检测域名是否可通过 IPv6 访问。输入主机名后,它会同时解析 A 与 AAAA 记录、验证双栈可达性并估算 IPv6 延迟,让你在把 IPv6 客户端或 IPv6 代理指向它之前先心里有数。

AAAA 记录是什么意思

A 记录把主机名映射到 IPv4 地址,AAAA 记录则映射到 IPv6 地址。如果域名没有 AAAA 记录,纯 IPv6 客户端无论如何都无法直接访问。存在 AAAA 记录只是支持 IPv6 的第一步,地址还必须真的可以连通,所以本工具会实际探测,而不是只看 DNS。

什么是双栈

双栈指主机同时发布 A 与 AAAA 记录并在两种协议上提供服务,这是现代网站的常规配置:IPv6 客户端走 IPv6,其他人继续走 IPv4。如果域名 IPv4 正常但已发布的 AAAA 地址超时,则属于配置错误,IPv6 用户会时好时坏。

这对代理意味着什么

IPv6 地址资源充裕,IPv6 代理比 IPv4 便宜得多,面向支持 IPv6 的目标(包括 Google 与 YouTube)表现很好;面向仅支持 IPv4 的目标则需要回退方案。先检测目标就能知道该买哪种资源,Rainproxy 的 IPv6 套餐也内置 IPv4 回退,正是为本工具会标出的这些情况准备的。
