IPv6 Tester
Enter a domain to check whether it supports IPv6.
Runs in your browser. Proxyon doesn't log or store the result.
What It Checks
IPv6 support
Whether the domain resolves and responds over IPv6.
Any domain
Test your own site, a target site, or any domain you're curious about.
Instant result
Supported or not, in seconds, no setup required.
How to Use It
Enter a domain, e.g. example.com.
Click Test.
See whether that domain supports IPv6.
Test another domain any time, no limits.
Why Use This
Confirms before you rely on it.
IPv6-only tools and proxies fail immediately if the target domain doesn't actually support IPv6. Testing first avoids debugging a "broken" setup that was never going to work.
No install, no setup.
Paste a domain and get an answer. No command line, no local tooling, no browser extension.
Works for any domain.
Check your own site before launch, or check a target site before pointing an IPv6 proxy or scraper at it.
Works With Any Domain
Test your own site, a target site, or any domain you're curious about. It isn't tied to Proxyon infrastructure. That said, if you're setting up IPv6 proxies, Proxyon's start from $0.25/IP for datacenter or $20/month for rotating, both pay-as-you-go with no subscription. Full breakdown on the pricing page.
Frequently Asked Questions
Everything else you might want to know about the tester.
What exactly does this check?
It checks whether the domain you enter has a working IPv6 route, meaning it resolves and responds over IPv6, not just IPv4.
The result says IPv6 isn't supported. What does that mean?
It means that domain has no working IPv6 route right now, either because it has no AAAA DNS record or nothing answers on it. Any tool or proxy that specifically requires IPv6 to reach that domain will fail.
Can I use this to check if a target site works with an IPv6 proxy?
Yes. Enter the target domain and this confirms whether it supports IPv6 at all before you wire an IPv6 proxy into a scraper or script.
Is anything logged?
Not by Proxyon beyond what's needed to run the check. We don't store results.

What Does "IPv6 Not Supported" Mean?
It means the domain you tested has no working route over the IPv6 internet right now, either because it has no AAAA DNS record or its server isn't answering on IPv6. IPv4 traffic to that domain is unaffected, but any tool, proxy, or script that specifically requires an IPv6 connection to it will fail.
Why Would a Domain Not Support IPv6?
Most commonly the hosting provider or CDN hasn't enabled it, or DNS has an A record but no AAAA record. Some sites support IPv6 on their main domain but not on subdomains or specific services, so it's worth testing the exact host you plan to connect to.
Can I Test a Target Site Before Pointing a Proxy At It?
Yes, that's the main use case. Enter the target domain and this confirms whether it actually supports IPv6 before you wire an IPv6 proxy into a scraper or script and start debugging blind.
Why Does This Matter for Scraping and Automation?
A script pointed at an IPv6-only proxy talking to a target that doesn't support IPv6 will fail immediately, and the error it throws rarely says why. Testing the target domain first turns a confusing connection failure into a five-second check, and confirms the problem is IPv6 support rather than your code, your credentials, or the proxy.
