6.1. Displaying existing IPv6 addresses

First you should check, whether and which IPv6 addresses are already configured (perhaps auto-magically during stateless auto-configuration). 6.1.1. Using "ip"

Usage:

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

Example for a static configured host:

# /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 

Example for a host which is auto-configured

Here you see some auto-magically configured IPv6 addresses and their lifetime.

# /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

6.1.2. Using "ifconfig"

Usage:

# /sbin/ifconfig <interface>

Example (output filtered with grep to display only IPv6 addresses). Here you see different IPv6 addresses with different scopes.

# /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
