Adding DNS' to Ubuntu without editing `etc/resolv.conf` [duplicate]

The internet on my network works with primary dns a.b.c.d and alternate as e.f.g.h and everytime I need it to work I need to append nameserver a.b.c.d and nameserver e.f.g.h to /etc/resolv.conf. Isn't there an easier way to do this that probably doesn't involve me doing this when PC restarts, I tried scripts, it works but it just seems as a hack.

Answer 1

Manually add those name servers in your /etc/network/interfaces file by inserting the line dns-nameservers a.b.d.c e.f.g.h underneath the interface(s) you are using (usually either eth0 or wlan0)

Answer 2

You can either do it by adding the DNS server in the /etc/network/interfaces adding the parameter dns-nameservers separating each DNS server with a space as following:

dns-nameservers 1.2.3.4 5.6.7.8

Example:

dns-nameservers 8.8.8.8 10.10.10.254

You can also edit the file /etc/resolvconf/resolv.conf.d/base and edit it the same way you edit the /etc/resolv.conf

Example:

nameserver 8.8.8.8
nameserver 10.10.10.254
search domain.local
