Q. How do I change existing name server IP address? How do I configure DNS name server IP address under Ubuntu Linux / Debian Linux? How do I configure DNS name resolution under Ubuntu Linux?

A. You need to edit /etc/resolv.conf file under Debian / Ubuntu Linux to set Name server IP address that the resolver should query. Up to 3 name server internet IP address can be defined. If there are multiple servers, the resolver library queries them in the order listed.

Ubuntu Linux Configure DNS Name resolution

Type the following command, enter:
$ sudo /etc/resolv.conf
Append your ISP name server or free fast dns nameservers IP address as follows:
nameserver 208.67.222.222 nameserver 208.67.220.220 nameserver 202.51.5.52
Save and close the file. Test your dns configuration by typing the following commands:
$ host yahoo.com $ nslookup google.com $ ping nixcraft.in
