HP-UX IP Address and Client Management Administrator's Guide (October 2009)

type
Specifies an encoded 16-bit value that specifies the resource record type
data
Specifies the resource data. The format of the data is specific to the type and class of
the resource record.
Following is a sample resource record:
. 3600000 IN NS A.ROOT-SERVERS.NET.
Table 2-1 lists the different types of resource records in BIND.
Table 2-1 BIND Resource Records
DescriptionName
Specifies the global position. The GPOS record must be superseded by the LOC record.Global Position (GPOS)
Specifies the geographic location of the service. LOC enables DNS to carry location
information about hosts, networks, and subnets. The LOC record supersedes the
GPOS record.
Location Information (LOC)
Provides rules for mapping certain parts of uniform resource identifiers (URIs) to
domain names. By changing the mapping rules, the host that is contacted to resolve
a URI can be changed.
Naming Authority Pointer
(NAPTR)
Maps a domain name to an OSI network service access point address as described
in RFC 1706 (The Naming Authority Pointer (NAPTR) DNS Resource Record). NSAP
to name translation is accomplished using the PTR RR as described in RFC 1035
(Domain Names - Implementation and Specification). The PTR RR can be used with
any NSAP address format.
Network Service Access Point
(NSAP)
Maps between RFC 822 (Standard for the format of ARPA Internet text) and X.400
addresses.
Mail Mapping Information
(PX)
Specifies the responsible person for a domain.
Responsible Person (RP)
Describes the well known services supported by a particular protocol on a particular
Internet address. This record must be superseded by the service record.
Well Known Service (WKS)
Provides a method to delegate authorization for one node, to provide key exchange
services on behalf of one or more nodes.
Key Exchanger (KX)
Map host names to IP addresses
Address (A)
Specifies an alias for official name of the host, also called the canonical name
Canonical Name (CNAME)
Specifies a weighted list of hosts that Sendmail tries while sending a mail to a
destination
Mail Exchanger (MX)
Specifies the name servers authoritative for a given domain
Name Server (NS)
Maps the IP addresses back to host names
Pointer (PTR)
Defines the hosts that support the defined services
Service (SRV)
Stores the private key of a key pair in the form of a digital signature on an RRset
Signature (SIG)
Designates the start of a domain and specifies that the server is authoritative for the
data in the domain
Start of Authority (SOA)
Provide a negative response to a domain name search by indicating that the next
domain name in lexicographical order is the one specified in this particular RR
Next (NXT)
Stores different kinds of cryptographic keys
Key (KEY)
Provides the capability to map an entire subtree of the DNS name space to another
domain
Domain Name (DNAME)
Stores the 128-bit IPv6 addresses with an IPv6 reverse mapping domain, ip6.int“Quad A” record (AAAA)
