DNS - Domain Name System
The domain name service (DNS) provided by Joker.com, your internet provider or your webhosting company, which is essential if you want to actually use your domain.
It is included in all Joker.com domains.
The name service makes your domain "work" in such a way, that your web site can be accessed, and emails to you are routed correctly into your inbox. The DNS is responsible to "translate" your domain name into an IP address, which is the resource used by the networks.
