Eu tenho um vserver com 16.04. com duas 64 sub-redes IPv6 atribuídas.
Estou tentando obter um endereço IPv6 aleatório com o SLAAC para comunicação com servidores externos.
Este é o meu / etc / network / interfaces
auto ens3
iface ens3 inet dhcp
iface ens3 inet6 auto
No entanto, não recebo um endereço IPv6. Esta é a saída de ip a ip -6 a
1: lo: mtu 65536 state UNKNOWN qlen 1
inet6 ::1/128 scope host valid_lft forever preferred_lft forever
2: ens3: mtu 1500 state UP qlen 1000
inet6 fe80::5054:a1ff:fe87:f16f/64 scope link valid_lft forever preferred_lft forever
Eu posso adicionar endereços IPv6 manualmente com
sudo ip -6 addr add [NEW_ADDRESS]/64 dev ens3
que me dá a seguinte saída de ip -6 a e um endereço IPv6 em funcionamento
1: lo: mtu 65536 state UNKNOWN qlen 1
inet6 ::1/128 scope host valid_lft forever preferred_lft forever
2: ens3: mtu 1500 state UP qlen 1000
inet6 [NEW_ADDRESS]/64 scope global valid_lft forever preferred_lft forever
inet6 fe80::5054:a1ff:fe87:f16f/64 scope link valid_lft forever preferred_lft forever
Esta é a saída do sudo sysctl -a | grep net.ipv6.conf | grep -i ens3
