Does notion.so support IPv6?
Partly. On November 6, 2026, www.notion.com answered over IPv6, but its home page loads from 3 hosts and 1 of them is IPv4-only, so an IPv6-only connection gets the page with those parts missing.
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.
- videos.ctfassets.net — link rel=preconnect, <source src>
Every host the notion.so home page loads from
| Host | Protocol | AAAA record |
|---|---|---|
| www.notion.comThe page itself | IPv6 | 2602:f79a::1 |
| videos.ctfassets.net | IPv4 only | — |
| images.ctfassets.net | IPv6 | 2600:9000:20a8:8a00:12:94b3:c380:93a1 |
Can I reach notion.so through an IPv6 proxy?
An IPv6-only route reaches the site but not every resource. Use IPv4, or a plan that falls back to IPv4, when the missing parts matter to you, such as a script that renders prices.
How this was measured
The IPv6 test loaded https://www.notion.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.
