		A (address record): IPv4 address. This is the most common form to point a domain to an IPv4 address.
				CNAME (canonical name record): alias
				MX (mail exchange): an email server. This information is used by other email servers to find where to send email addressed to a given address. Each MX record has a priority. The highest-priority server (with the lowest number) is tried first (see sidebar B.A.-BA SMTP); other servers are contacted in order of decreasing priority if the first one does not reply.
				PTR (pointer): mapping of an IP address to a name. Such a record is stored in a “reverse DNS” zone named after the IP address range. For example, 1.168.192.in-addr.arpa is the zone containing the reverse mapping for all addresses in the 192.168.1.0/24 range.
				AAAA (IPv6 address record): IPv6 address.
				NS (name server): maps a name to a name server. Each domain must have at least one NS record. These records point at a DNS server that can answer queries concerning this domain; they usually point at the primary and secondary servers for the domain. These records also allow DNS delegation; for instance, the falcot.com zone can include an NS record for internal.falcot.com, which means that the internal.falcot.com zone is handled by another server. Of course, this server must declare an internal.falcot.com zone.
