F32-64 Problème résolution DNS

Bonjour,

Sur F32-64, pas de résolution DNS.

Je précise : j'ai enlevé Network-Manager, puis configuré le fichier :

systemctl list-unit-files | grep NetworkManager
NetworkManager-dispatcher.service          disabled        enabled      
NetworkManager-wait-online.service         disabled        enabled      
NetworkManager.service                     disabled        enabled   

Je peux pinguer une @IP extérieure, réseau interne mais pas un nom de domaine extérieur :

 ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
64 bytes from 8.8.8.8: icmp_seq=1 ttl=117 time=3.60 ms
64 bytes from 8.8.8.8: icmp_seq=2 ttl=117 time=3.32 ms
64 bytes from 8.8.8.8: icmp_seq=3 ttl=117 time=3.17 ms

Peut-être tout simplement parce que tu es en ipv6 et que tu as mis des dns ipv4 ?
