Does zoom.us support IPv6?
Partly. On November 6, 2026, www.zoom.com answered over IPv6, but its home page loads from 8 hosts and 2 of them are 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.
- cdn.bc0a.com — <script src>
- logx.optimizely.com — link rel=preconnect
Every host the zoom.us home page loads from
| Host | Protocol | AAAA record |
|---|---|---|
| www.zoom.comThe page itself | IPv6 | 2407:30c0:183::aa72:4e50 |
| cdn.bc0a.com | IPv4 only | — |
| logx.optimizely.com | IPv4 only | — |
| cdn.cookielaw.org | IPv6 | 2606:4700::6812:572a |
| cdn.optimizely.com | IPv6 | 2606:4700::6812:4239 |
| st1.zoom.us | IPv6 | 2407:30c0:181::1 |
| us01ccistatic.zoom.us | IPv6 | 2407:30c0:180::1 |
| www.googletagmanager.com | IPv6 | 2a00:1450:4010:c0e::61 |
Can I reach zoom.us 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.zoom.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.
