CNAME - Alias of one name to another
MX - List of mail exchange servers that accept email for a domain
NS - Name server record
PTR - Pointer to a canonical name
SOA - Specifies authoritative information about a DNS zone, including the primary name server, the email of the domain administrator, the domain serial number, and several timers relating to refreshing the zone.
SOA - Generalized service location record, used for newer protocols instead of creating protocol-specific records such as MX
