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
