What is a DNS server?

DNS stands for “Domain Name System”. The name reveals what the task of the server involves. It is responsible for the name resolution of a network. It manages the DNS records, so to speak. The DNS server is thus an extremely important service!

The DNS server manages IP-addresses and the associated Internet page namesvisually comparable to a telephone. You know the phone number (IP), but not the address (domain). The DNS server solves this problem. The DNS server converts the provided Request to the domain to thecorresponding IP address (=name resolution).

Among its “phone numbers” it counts the IPv4 and IPv6 addresses. The first version of IP addresses IPv4 shows a 10-digit number. With IPv6 addresses, larger number combinations are possible. IPv6 was introduced because too many addresses were assigned.

How does a DNS server work?

The DNS server is set by default in the router by your Internet provider. A DNS server translatesdomain names into IP addresses. There is a primary and a secondary name server. This way you are protected from failures. The Secondary Server is a replication/back-up of the First.

A DNS server is additionally equipped with a cache. Here the requests are stored to save the resources of the server. With the cache function, domains are accessible even though they have moved. However, the cache is cleaned regularly. Exactly the cache that stores the history of your search queries and domains.
