Hi, I attempted to establish an IPv6 connection from my home network (FiOS, AS701) to a destination under China Telecom AS4134, but was unsuccessful. However, other ISPs such as Xfinity and Starlink can successfully establish this connection. You can verify this by conducting a traceroute with HE.net probes.
IPv4 connections are working fine.
Any ideas on how to resolve this issue? Thanks.
Solved! Go to Correct Answer
China Telecom has a lot of prefixes announced under them.

Is there a specific IP address or IP range which you're having trouble with? It might be worth checking the BGP Routes as well as performing a Traceroute from Verizon's own Looking Glass service to see what might be going on.

You can select servers across the world which Verizon owns. Their peering points to China Telecom are likely to be in the West Coast United States, so try those locations first.
Same here. IPv4 can reach AS4134 but not via IPv6, either through AS701 (Fios) or AS703 (Wireless).
As a workaround, you can disable native Verizon IPv6 stack and use HE.net IPv6 tunnel broker instead.
