→DNS Record Types
Line 136:
MX Mail exchange record Maps a domain name to a list of message transfer agents for that domain
NS Name server record Delegates a DNS zone to use the given authoritative name servers
PTR Pointer record Pointer to a canonical name. Unlike a CNAME, DNS processing stops and just the name is returned. The most common use is for implementing reverse
DNS lookups.
SOA Start of [a zone of] authority record Specifies authoritative information about a DNS zone, including the primary name server, the email of the domain administrator, the domain serial
number,etc
SRV Service locator Generalized service location record, used for newer protocols instead of creating protocol-specific records such as MX.
TXT Text record Originally for arbitrary human-readable text in a DNS record. Now more often carries machine-readable data, opportunistic encryption, Sender Policy
Framework, etc.
* All cached records Returns all cached records of all types known to the name server. If the name server does not have any information on the name, the request will be
forwarded on.
AXFR Authoritative Zone Transfer Transfer entire zone file from the master name server to secondary name servers.
IXFR Incremental Zone Transfer Requests a zone transfer of the given zone but only differences from a previous serial number.
