CoreDNS: add IPv6 DNS server results in "Invalid address or port"

patient0

I tried to add the Quad9 DNS servers, 9.9.9.9, 149.112.112.112 and 2620:fe::fe and 2620:fe::9 as CoreDNS DNS servers.
The IPv4 addresses are accepted but entering the IPv6 addresses results in "Invalid address or port".

Is that supposed to work?

Edit: adding a screenshot

@patient0 yeah looks like a parsing isssue - write out the full address vs shorthand

mr_nets

I confirm, you can't put anything than an IPv4 address . I tried with the Cloudflare address short and full

2606:4700:4700::1112
2606:4700:4700:0000:0000:0000:0000:1112

Has anyone managed to set up an IPv6 address?

just to clarify: I did try every combination and it didn't work, like

2620:fe::fe
2620:fe:0:0:0:0:0:fe
2620:fe:0000:0000:0000:0000:0000:fe
2620:00fe:0000:0000:0000:0000:0000:00fe

Have disabled it again after that and will check back on Nexus in a year or two, so many rough edges.
