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.
- www.coursera.org — the page itself
- coursera_assets.s3.amazonaws.com — <style> url()
- d3njjcbhbojbot.cloudfront.net — link rel=preconnect, link rel=apple-touch-icon, link rel=icon, link rel=preload
Every host the coursera.org home page loads from
| Host | Protocol | AAAA record |

Can I reach coursera.org through an IPv6 proxy?
An IPv6-only route cannot reach this site. Use residential IPv4.
How this was measured
The IPv6 test loaded https://www.coursera.org/ 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.
