EDITAR : Eu tentei algo diferente com base na pesquisa. Este é o meu /etc/network/interfaces
:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# This line makes sure the interface will be brought up during boot
auto eth0

# The primary network interface
iface eth0 inet static

# up commands
up ip addr add 85.17.141.33/24 dev eth0
up ip -6 addr add 2001:1af8:4100:a00e:4::1/64 dev eth0
up ip -6 ro add default via 2001:1af8:4100:a00e::1 dev eth0
Em seguida, ip addr show eth0
outputs:

de saídas:

default via fe80::2d0:2ff:fe33:3c00 dev eth0 proto kernel metric 1024 expires 1627sec
Eventualmente, as duas rotas padrão do kernel proto desaparecem da saída. Minha conexão IPv6 ainda caiu em algum momento durante a noite. Novamente, simplesmente executando sudo service networking stop && sudo service networking start
fez tudo funcionar novamente. Essas duas rotas fe80
reapareceram também, não surpreendendo. Alguém tem alguma ideia?
aparte : em nenhum momento qualquer conexão IPv4 teve problemas.
