I am trying to set both a static ipv4 address and a static ipv6 address on a home hosted Debian 11 server (it's actually just a PC).
Here is my /etc/network/interfaces :
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eno1
iface eno1 inet static
address 192.168.1.149
netmask 24
gateway 192.168.1.1
iface eno1 inet6 static
address 2a01:xxxx:xxxx:xxxx::1234
netmask 56
gateway fe80::712a:e39b:d35a:3ea4
After restarting networking service with `sudo service netowrking restart" Here is the result (exactyly what i want):
sept. 15 00:07:56 omen-debian systemd[1]: Starting Raise network interfaces...
sept. 15 00:08:07 omen-debian ifup[785]: Waiting for DAD... Timed out

As you see my networking service produces an error. What am i doing wrong ?
