#iface eth0 inet DHCP

iface eth0 inet static
address 192.168.80.129
netmask 255.255.255.0
gateway 192.168.80.2

Setting up a DNS server

Are configured within this file/etc/resolv.conf.

Content:

NameServer 192.168.80.2
NameServer 8.8.8.8

Save exit.

Note: After restarting Ubuntu, it is not possible to surf the internet again, the problem is/etc/resolv.conf. Once restarted, the DNS for this file configuration is automatically modified to the default value. So you need to permanently modify DNS. Here's how:

# Vim/etc/resolvconf/resolv.conf.d/base
NameServer 192.168.80.2
NameServer 8.8.8.8

3. Restart the networking service to make it effective:

#/etc/init.d/networking Restart

This allows the network configuration to be permanently active.
