Does github.com support IPv6?
FailChecked · Software and payments
No. On November 6, 2026, github.com published no AAAA record, so its home page cannot be opened over an IPv6-only connection at all.

Hosts that block an IPv6-only load
These hosts publish an IPv4 address but no AAAA record. Over an IPv6-only connection the browser cannot fetch anything they serve.
- github.com — the page itself, link rel=manifest
- github-cloud.s3.amazonaws.com — link rel=dns-prefetch
Every host the github.com home page loads from

Can I reach github.com through an IPv6 proxy?
An IPv6-only route cannot reach this site. Use residential IPv4.
How this was measured
The IPv6 test loaded https://github.com/ once on November 6, 2026, read every host the returned HTML asks a browser to fetch, and looked up AAAA and A records for each. Hosts added later by JavaScript are not counted, and other pages on the site can depend on different hosts. Results change as sites move providers.
