Kita dapat mencek, apakah IPv6 address sudah dikonfigurasi secara automatic saat stateless auto-configuration.

Menggunakan "ip"

Penggunaan

# /sbin/ip -6 addr show dev <interface>

Contoh untuk host dengan statik konfigurasi

# /sbin/ip -6 addr show dev eth0
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
    inet6 2001:470:36:ab6::4f0/128 scope global 
    inet6 2001:470:36:ab6:e47e:a439:2e5d:44a4/64 scope global temporary dynamic 
    inet6 2001:470:36:ab6:62a4:4cff:fe75:a6a0/64 scope global dynamic 
    inet6 fe80::62a4:4cff:fe75:a6a0/64 scope link 

Sementara untuk host yang secara automatic di konfigurasi IPv6 dan ada lifetime-nya

# /sbin/ip -6 addr show dev eth0 
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
    inet6 2001:470:36:ab6::4f0/128 scope global 
       valid_lft forever preferred_lft forever
    inet6 2001:470:36:ab6:e47e:a439:2e5d:44a4/64 scope global temporary dynamic 
       valid_lft 6974sec preferred_lft 1574sec
    inet6 2001:470:36:ab6:62a4:4cff:fe75:a6a0/64 scope global dynamic 
       valid_lft 6974sec preferred_lft 1574sec
    inet6 fe80::62a4:4cff:fe75:a6a0/64 scope link 
       valid_lft forever preferred_lft forever

Penggunaan "ifconfig"

Penggunaan:

# /sbin/ifconfig <interface>

Contoh (output di filter menggunakan grep untuk menampilkan hanya address IPv6 saja). Disini kita bisa melihat IPv6 yang berbeda mempunyai scope yang berbeda.

# /sbin/ifconfig eth0 |grep "inet6 addr:"
inet6 addr: 2001:470:36:ab6:62a4:4cff:fe75:a6a0/64 Scope:Global
inet6 addr: 2001:470:36:ab6:e47e:a439:2e5d:44a4/64 Scope:Global
inet6 addr: fe80::62a4:4cff:fe75:a6a0/64 Scope:Link
inet6 addr: 2001:470:36:ab6::4f0/128 Scope:Global
