About domain names

This is how the domain name system works

The domain name system (DNS) represents the “telephone book” of the Internet. Similar to look up a name in the telephone book to find a phone number, you look up addresses in DNS to find an IP address.

This is DNSSEC

DNSSEC (DNS Security Extensions) is a security extension to DNS. DNSSEC protected domains are cryptographically signed, and this makes it possible to check that the reply to a domain lookup comes from the correct source of origin, and that the lookup has remained unchanged.
