DESCRIPTION

  "This MIB module defines textual conventions for

   representing Internet addresses. An Internet

   address can be an IPv4 address, an IPv6 address

   or a DNS domain name."

REVISION     "200006080000Z"

DESCRIPTION

    "Initial version, published as RFC 2851."

::= { mib-2 76 }

InetAddressType ::= TEXTUAL-CONVENTION

  STATUS      current

  DESCRIPTION

      "A value that represents a type of Internet address.

       unknown(0)  An unknown address type. This value MUST

                   be used if the value of the corresponding

                   InetAddress object is a zero-length string.

                   It may also be used to indicate an IP address

                   which is not in one of the formats defined

                   below.

       ipv4(1)     An IPv4 address as defined by the

                   InetAddressIPv4 textual convention.

       ipv6(2)     An IPv6 address as defined by the

                   InetAddressIPv6 textual convention.

       dns(16)     A DNS domain name as defined by the

                   InetAddressDNS textual convention.

       Each definition of a concrete InetAddressType value must be

       accompanied by a definition of a textual convention for use

       with that InetAddressType.

       The InetAddressType textual convention SHOULD NOT be subtyped

       in object type definitions to support future extensions. It

       MAY be subtyped in compliance statements in order to require

       only a subset of these address types for a compliant

       implementation."

  SYNTAX      INTEGER {

                  unknown(0),

                  ipv4(1),    -- these named numbers are aligned

                  ipv6(2),    -- with AddressFamilyNumbers from

                  dns(16)     -- IANA-ADDRESS-FAMILY-NUMBERS-MIB

              }

InetAddress ::= TEXTUAL-CONVENTION

  STATUS       current

  DESCRIPTION

      "Denotes a generic Internet address.

       An InetAddress value is always interpreted within the

       context of an InetAddressType value. The InetAddressType

       object which defines the context must be registered

       immediately before the object which uses the InetAddress

       textual convention. In other words, the object identifiers

       for the InetAddressType object and the InetAddress object

       MUST have the same length and the last sub-identifier of

       the InetAddressType object MUST be 1 less than the last

       sub-identifier of the InetAddress object.

       When this textual convention is used as the syntax of an

       index object, there may be issues with the limit of 128

       sub-identifiers specified in SMIv2, STD 58. In this case,

       the OBJECT-TYPE declaration MUST include a 'SIZE' clause

       to limit the number of potential instance sub-identifiers."

InetAddressIPv4 ::= TEXTUAL-CONVENTION

  DISPLAY-HINT "1d.1d.1d.1d"

  STATUS       current

  DESCRIPTION

      "Represents an IPv4 network address:

         octets   contents         encoding

          1-4     IP address       network-byte order

       The corresponding InetAddressType value is ipv4(1)."

  SYNTAX       OCTET STRING (SIZE (4))

InetAddressIPv6 ::= TEXTUAL-CONVENTION

  DISPLAY-HINT "2x:2x:2x:2x:2x:2x:2x:2x%4d"

  STATUS       current

  DESCRIPTION

      "Represents an IPv6 network address:

         octets   contents         encoding

          1-16    IPv6 address     network-byte order

         17-20    scope identifier network-byte order

       The corresponding InetAddressType value is ipv6(2).

       The scope identifier (bytes 17-20) MUST NOT be present

       for global IPv6 addresses. For non-global IPv6 addresses

       (e.g. link-local or site-local addresses), the scope

       identifier MUST always be present. It contains a link

       identifier for link-local and a site identifier for

       site-local IPv6 addresses.

       The scope identifier MUST disambiguate identical address

       values. For link-local addresses, the scope identifier will

       typically be the interface index (ifIndex as defined in the

       IF-MIB, RFC 2233) of the interface on which the address is

       configured.

       The scope identifier may contain the special value 0

       which refers to the default scope. The default scope

       may be used in cases where the valid scope identifier

       is not known (e.g., a management application needs to

       write a site-local InetAddressIPv6 address without

       knowing the site identifier value). The default scope

       SHOULD NOT be used as an easy way out in cases where

       the scope identifier for a non-global IPv6 is known."

  SYNTAX       OCTET STRING (SIZE (16|20))

InetAddressDNS ::= TEXTUAL-CONVENTION

  DISPLAY-HINT "255a"

  STATUS       current

  DESCRIPTION

      "Represents a DNS domain name. The name SHOULD be

       fully qualified whenever possible.

       The corresponding InetAddressType is dns(16).

       The DESCRIPTION clause of InetAddress objects that

       may have InetAddressDNS values must fully describe

       how (and when) such names are to be resolved to IP

       addresses."
