Type Value
(decimal)
RFC Description Function
A 1 1035 Address Record Returns a 32-bit IPv4 address, most commonly
used to map hostnames to an IP address of
the host, but also used for DNSBLs, storing
subnet masks in RFC 1101, etc.
AAAA 28 3596 IPv6 Address Record Returns a 128-bit IPv6 address, most
commonly used to map hostnames to an IP
address of the host.
CNAME 5 1035 Canonical Name
Record
Alias of one name to another: the DNS lookup
will continue by retrying the lookup with the
new name.
MX 15 1035 Mail Exchange Record Maps a domain name to a list of message
transfer agents for that domain
NAPTR 35 3403 Naming Authority
Pointer
Allows regular expression based rewriting of
domain names which can then be used as
URIs, further domain names to lookups, etc.
NS 2 1035 Name Server Record Delegates a DNS zone to use the given
authoritative name servers.
PTR 12 1035 Pointer Record Pointer to a canonical name. Unlike a CNAME,
DNS processing does
NOT proceed, just the
name is returned. The most common use is for
implementing reverse DNS lookups, but other
uses include such things as DNS-SD.
