What is DNS (Domain Name System)?
DNS is the system used to convert internet domain names to IP addresses and IP addresses to domain names. DNS servers enable the
resolution of URL (Uniform Resource Locator) or FQDN (Fully Qualified Domain Name) addresses to IP addresses. This way, instead of memorizing IP addresses, we use more memorable host addresses, i.e., domain addresses.
DNS, nameservers (name servers) and DNS
resolvers are the most important components that make up the DNS system. Converting domain names to IP addresses is made possible by DNS resolvers. Netinternet’s data center contains 4 IPv4 and IPv6 enabled DNS resolver servers, and these servers are only used on
servers within the data center.
IPv4 DNS Resolver
159.253.34.4
159.253.34.5
IPv6 DNS Resolver
2a03:2100::4
2a03:2100::5
Changing DNS Resolver on Linux Operating Systems
The
file path you need to edit to change DNS resolver addresses on Linux operating systems: /etc/resolv.conf
After opening the file with any editor installed on your operating system, you need to update the information by writing nameserver at the beginning for each
DNS resolver.

Changing DNS Resolver on Windows Operating System
To change DNS resolver addresses on Windows operating systems, go to the properties of the active network connection via “Network Connections”, click on
“Internet Protocol Version 4” and press the properties button. On the screen that appears (like the right window in the image below), you can define DNS resolver servers.
