freedesktop.org Gitlab NetworkManager NetworkManager issues 1298 0 None opened Support RFC 8925 (IPv6-Only Preferred Option for DHCPv4) dhcp option 108 AKA IPv6-Mostly 2023-05-29 09:15:40 UTC

Description Petr Menšík 2023-05-29 09:03:58 UTC 
Network can signal it can support IPv4, but requests all prepared systems to use only IPv6 addresses. That can be interesting especially where no IPv4 NAT is done and hosts get assigned public addresses.

Reproducible: Always

Steps to Reproduce:
1. DHCP server offers ipv6-only extension
2. Connect to such network
3. IPv4 address should not be allocated, even if the network provides DHCPv4
