merci pour ce retour circonstancié.
effectivement, le problème se situerait dans la configuration de
l'interface eth0, partie IPv6, j'ai suivi les recommandations de cette
page :
https://documentation.online.net/fr/dedicated-server/network/ipv6/prefix
j'ai appliqué les 2 premiers points (Configurer le client DHCPv6 +
Démarrage du client DHCPv6 avec SystemD),
j'ai l'impression que 'dhclient' se lance deux fois, voici les éléments
que je peux fournir :
# cat /etc/systemd/system/dhclient.service

ExecStart=/sbin/dhclient -cf /etc/dhcp/dhclient6.conf -6 -P -v eth0
[Install]
WantedBy=multi-user.target
