Not so often needed, be carefully with removing non existent IPv6 address, sometimes using older kernels it results in a crash.
Using "ip"
Usage:
# /sbin/ip -6 addr del <ipv6address>/<prefixlength> dev <interface>
Example:
# /sbin/ip -6 addr del 2001:0db8:0:f101::1/64 dev eth0
Using "ifconfig"
Usage:
# /sbin/ifconfig <interface> inet6 del <ipv6address>/<prefixlength>
Example:
# /sbin/ifconfig eth0 inet6 del 2001:0db8:0:f101::1/64

Example
There is an inet6 addr on the eth0 interface:
eth0 Link encap:Ethernet HWaddr 00:0c:29:d9:46:f5
inet6 addr: fe80::20c:29ff:fed9:46f5/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:38 errors:0 dropped:0 overruns:0 frame:0
TX packets:193 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:4133 (4.1 KB) TX bytes:32902 (32.9 KB)
Interrupt:19 Base address:0x2024
I don't need this address and I use the following command to delete it:
sudo ifconfig eth0 inet6 del fe80::20c:29ff:fed9:46f5/64
