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:

  1. /sbin/ip -6 addr show dev <interface>

Example for a static configured host:

  1. /sbin/ip -6 addr show dev eth0

2: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_ fast qlen 100 inet6 fe80::210:a4ff:fee3:9566/10 scope link inet6 2001:0db8:0:f101::1/64 scope global inet6 fec0:0:0:f101::1/64 scope site

Example for a host which is auto-configured

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

  1. /sbin/ip -6 addr show dev eth0

3: eth0: <BROADCAST,MULTICAST,PROMISC,UP> mtu 1500 qdisc pfifo_fast qlen ¬ 100 inet6 2002:d950:f5f8:f101:2e0:18ff:fe90:9205/64 scope global dynamic valid_lft 16sec preferred_lft 6sec inet6 3ffe:400:100:f101:2e0:18ff:fe90:9205/64 scope global dynamic valid_lft 2591997sec preferred_lft 604797sec inet6 fe80::2e0:18ff:fe90:9205/10 ¬ scope link

6.1.2. Using "ifconfig"

Usage:

  1. /sbin/ifconfig <interface>

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

  1. /sbin/ifconfig eth0 |grep "inet6 addr:"

inet6 addr: fe80::210:a4ff:fee3:9566/10 Scope:Link inet6 addr: 2001:0db8:0:f101::1/64 Scope:Global inet6 addr: fec0:0:0:f101::1/64 Scope:Site
