Eu tenho isto:
auto enp0s25
iface enp0s25 inet static
address 204.12.250.178
netmask 255.255.255.248
gateway 204.12.250.177
dns-nameservers 192.187.107.16 69.30.209.16
iface enp0s25:1 inet static
address 204.12.250.179
netmask 255.255.255.248
gateway 204.12.250.177
dns-nameservers 192.187.107.16 69.30.209.16
Mas quando tento mencioná-lo, recebo o erro:
