How do you change your DNS settings in Linux/Windows?

On Windows:

1. Go to Control Panel > Network and Internet > Network and Sharing Center > (on the left bar) Change Adapter Settings
2. Right-Click the adapter you want to configure and choose Properties
3. Double-Click Internet Protocel Version4 (TCP/IPv4)
4. You can set your DNS servers' address on the bottom half.

On Linux:

• Simply edit the following file: /etc/resolv.conf
• You add "nameserver xxx.xxx.xxx.xxx", where the x's are the IP addresses for your DNS server

Hello,

In Linux if you need local DNS you can modify it at resolve . conf as Mohammed say before ... but if you need public DNS you need to install BIND
