Editing DNS

{{Draft}}

[[wikipedia:Domain Name System]] translates domain names to [[IP]] addresses. The most common types of records stored in the DNS database are for Start of Authority ([[SOA]]), IP addresses (A and AAAA), SMTP mail exchangers (MX), [[name servers]] (NS), pointers for reverse DNS lookups (PTR), and domain name aliases ([[CNAME]]).

A stands for Address
AAAA are used for IPv6 addresses
