DNS is an acronym for Domain Name System. DNS is key to many network services run on the Internet or LAN (Local Area Network) such as:
- Internet browsing
- Mail server
- Web server
- Video streaming and more.
Almost all traffic on the Internets depends upon the DNS servers. Most ISP (Internet Service Provider) have their caching DNS server to reduce network load. But, how do you find out DNS server IP address? How do you find out current DNS server IP address? Under Linux, FreeBSD and all UNIX-like operating systems you have a file called /etc/resolv.conf. It is often known as the resolver configuration file. If you are using MS-Windows version 7 / 8 / 10 (or older Vista / NT / 2000 / XP / 98) then see below for how to find out DNS server address under MS-Windows operating systems.
