Hi, I got a trouble to ping a host which has some ipv4 addresses and some ipv6 addresses. But my network only support ipv4. It seems ping is not use ipv4 address. I tested this with chrome the result is same. I think it’s a issue from OS.
My manjaro version is 20.2 and get the latest update.
Thank you very much!
Chrome seems no problem now. But ping can work only first time (viz it get the ipv4 address) then it will almost hang (very very slow) when it get the ipv6 address.
For example
$ ping -6 res.wx.qq.com
PING res.wx.qq.com(2408:80f0:4105:101:23:: (2408:80f0:4105:101:23::)) 56 data bytes
64 bytes from 2408:80f0:4105:101:23:: (2408:80f0:4105:101:23::): icmp_seq=1 ttl=59 time=6.30 ms
64 bytes from 2408:80f0:4105:101:23:: (2408:80f0:4105:101:23::): icmp_seq=2 ttl=59 time=5.05 ms
The above response is very slow and it costs several minutes to print one line.

Seems your IPv6 is at least partially working. Unfortunately mine isn’t with the current ISP (partially working with previous) so I can’t test those things on this connection. No pub networks to try either for a while …
I will have to try the phone tether to see if that resolves IPv6.
Also I don’t know if there is any extra configuration needed in network settings … I’ll have to look in to that.
