ip version 6 (ipv6) Configuration on Linux

AutoConfiguration,
Auto configuration  is completely independent. Getting the mac address of the card and giving a random ipv6 address.

Static ipv6 configuration
# ——————————————————————————-
auto lo
iface lo inet loopback

auto eth0
allow-hotplug eth0
iface eth0 inet dhcp

iface eth0 inet6 static
address 2001:db8::xxxx:yyyy
netmask 64
gateway 2001:db8::xxxx:yy:zzzz
# —————————————————————————–
Your /etc/hosts file should read
127.0.0.1 localhost
127.0.1.1 serverubuntu//change this to 127.0.0.1
192.168.1.199 serverubuntu//add your static IP

# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
