About DNSCheck

The domain name system (DNS in short) is what could be called the ”phone book” of the Internet. It keeps track of the mapping of, for example, a human-readable website name (like www.iis.se) to the slightly more arcane form of an IP-address that the computer needs to initiate communication (in this case 212.247.7.229).

Besides browsing the Internet with your web browser using website names instead of IP-addresses the DNS also makes sure your emails find their way. In short, a stable DNS is vital for most companies to maintain a working and efficient operation.
