At ColdProxy, we provide both IPv4 and IPv6 proxies. However, it’s important to understand that not all websites or applications support IPv6 yet.
If your IPv6 proxy doesn’t work on a specific website or app, it doesn’t mean there is an issue with the proxy itself. In most cases, it means the website only supports IPv4 connections.
• Before You Buy: Always Check IPv6 Compatibility
To avoid any confusion or issues, we recommend that you check whether your target website or app supports IPv6 before purchasing an IPv6 proxy. You can use our tool to check:
You can also access our IPv6 check tool directly from our website:

What the IPv6 Checker Does
The IPv6 Checker is a DNS-based AAAA lookup tool that lets you quickly check whether a domain supports IPv6.
It checks:
- Website IPv6 (AAAA records)
- Mail servers (MX)
- Name servers (NS)
How the Check Works
How to check:
- Go to the link above.
- Enter the domain name of the website (google.com).
- Then the tool will perform a DNS-based lookup and display the results instantly.

What the Results Show
The IPv6 Checker provides complete results when you enter a domain, including:
- IPv6 support status for website, mail servers, and name servers (Yes/No indicators)
- Full list of IPv4 and IPv6 addresses for the domain
- Cross-checked results using multiple DNS resolvers for accuracy
- Instant DNS-over-HTTPS lookup (results in ~1 second)
- No signup required and no data stored
It also displays detailed DNS information such as:
- Website IP addresses (A and AAAA records)
- Mail server records (MX)
- Name server records (NS)
This gives a complete overview of whether a domain is IPv6-ready or only partially supported.

• Sites That Support IPv6:
Many major platforms fully support IPv6, including:
- YouTube
- Facebook (including Instagram and WhatsApp)
- Bing
- Yahoo
- Netflix
- LinkedIn and many more.
Because of this, tools like XEvil, CapMonster, and other automation services that rely on Google for solving CAPTCHAs will work with our IPv6 proxies.
