- 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. This module also defines
- textual conventions for Internet port numbers,
- autonomous system numbers and the length of an
- Internet address prefix."
- REVISION "200205090000Z"
- DESCRIPTION
- "Second version, published as RFC 3291. This
- revisions contains several clarifications and it
-
- introduces several new textual conventions:
- InetAddressPrefixLength, InetPortNumber,
- InetAutonomousSystemNumber, InetAddressIPv4z,
- and InetAddressIPv6z."

- 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) A global IPv6 address as defined by the
- InetAddressIPv6 textual convention.
-
- ipv4z(3) A non-global IPv4 address including a zone
- index as defined by the InetAddressIPv4z
- textual convention.
-
- ipv6z(4) A non-global IPv6 address including a zone
- index as defined by the InetAddressIPv6z
- 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.
-
- To support future extensions, the InetAddressType textual
- convention SHOULD NOT be sub-typed in object type definitions.
- It MAY be sub-typed in compliance statements in order to
- require only a subset of these address types for a compliant
- implementation.
-
- Implementations must ensure that InetAddressType objects
-
- and any dependent objects (e.g. InetAddress objects) are
- consistent. An inconsistentValue error must be generated
- if an attempt to change an InetAddressType object would,
- for example, lead to an undefined InetAddress value. In
- particular, InetAddressType/InetAddress pairs must be
- changed together if the address type changes (e.g. from
- ipv6(2) to ipv4(1))."

- InetAddress ::= TEXTUAL-CONVENTION
- STATUS current
- DESCRIPTION
- "Denotes a generic Internet address.
-
- An InetAddress value is always interpreted within the context
- of an InetAddressType value. Every usage of the InetAddress
- textual convention is required to specify the InetAddressType
- object which provides the context. It is suggested that the
- InetAddressType object is logically registered before the
- object(s) which use the InetAddress textual convention if
- they appear in the same logical row.
-
- The value of an InetAddress object must always be
- consistent with the value of the associated InetAddressType
- object. Attempts to set an InetAddress object to a value
- which is inconsistent with the associated InetAddressType
- must fail with an inconsistentValue error.
-
- 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 definition 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 IPv4 address network-byte order
-
- The corresponding InetAddressType value is ipv4(1).
-
- This textual convention SHOULD NOT be used directly in object
- definitions since it restricts addresses to a specific format.
- However, if it is used, it MAY be used either on its own or in
- conjunction with InetAddressType as a pair."
- SYNTAX OCTET STRING (SIZE (4))
-
- InetAddressIPv6 ::= TEXTUAL-CONVENTION
- DISPLAY-HINT "2x:2x:2x:2x:2x:2x:2x:2x"
- STATUS current
- DESCRIPTION
- "Represents an IPv6 network address:
-
- octets contents encoding
- 1-16 IPv6 address network-byte order
-
- The corresponding InetAddressType value is ipv6(2).
-
- This textual convention SHOULD NOT be used directly in object
- definitions since it restricts addresses to a specific format.
- However, if it is used, it MAY be used either on its own or in
- conjunction with InetAddressType as a pair."
- SYNTAX OCTET STRING (SIZE (16))
-
- InetAddressIPv4z ::= TEXTUAL-CONVENTION
- DISPLAY-HINT "1d.1d.1d.1d%4d"
- STATUS current
- DESCRIPTION
- "Represents a non-global IPv4 network address together
- with its zone index:
-
- octets contents encoding
- 1-4 IPv4 address network-byte order
- 5-8 zone index network-byte order
-
- The corresponding InetAddressType value is ipv4z(3).
-
- The zone index (bytes 5-8) is used to disambiguate identical
- address values on nodes which have interfaces attached to
- different zones of the same scope. The zone index may contain
- the special value 0 which refers to the default zone for each
- scope.
-
- This textual convention SHOULD NOT be used directly in object
-
- definitions since it restricts addresses to a specific format.
- However, if it is used, it MAY be used either on its own or in
- conjunction with InetAddressType as a pair."

-
- InetAddressIPv6z ::= TEXTUAL-CONVENTION
- DISPLAY-HINT "2x:2x:2x:2x:2x:2x:2x:2x%4d"
- STATUS current
- DESCRIPTION
- "Represents a non-global IPv6 network address together
- with its zone index:
-
- octets contents encoding
- 1-16 IPv6 address network-byte order
- 17-20 zone index network-byte order
-
- The corresponding InetAddressType value is ipv6z(4).
-
- The zone index (bytes 17-20) is used to disambiguate
- identical address values on nodes which have interfaces
- attached to different zones of the same scope. The zone index
- may contain the special value 0 which refers to the default
- zone for each scope.
-
- This textual convention SHOULD NOT be used directly in object

-
- 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.
-
- This textual convention SHOULD NOT be used directly in object
- definitions since it restricts addresses to a specific format.
- However, if it is used, it MAY be used either on its own or in
- conjunction with InetAddressType as a pair."
- SYNTAX OCTET STRING (SIZE (1..255))
-
- InetAddressPrefixLength ::= TEXTUAL-CONVENTION
- STATUS current
- DESCRIPTION
- "Denotes the length of a generic Internet network address
- prefix. A value of n corresponds to an IP address mask
- which has n contiguous 1-bits from the most significant
- bit (MSB) and all other bits set to 0.
-
- An InetAddressPrefixLength value is always interpreted within
- the context of an InetAddressType value. Every usage of the
- InetAddressPrefixLength textual convention is required to
- specify the InetAddressType object which provides the
- context. It is suggested that the InetAddressType object is
- logically registered before the object(s) which use the
- InetAddressPrefixLength textual convention if they appear in
- the same logical row.
-
- InetAddressPrefixLength values that are larger than
- the maximum length of an IP address for a specific
- InetAddressType are treated as the maximum significant
- value applicable for the InetAddressType. The maximum
- significant value is 32 for the InetAddressType
- 'ipv4(1)' and 'ipv4z(3)' and 128 for the InetAddressType
- 'ipv6(2)' and 'ipv6z(4)'. The maximum significant value
- for the InetAddressType 'dns(16)' is 0.
-
- The value zero is object-specific and must be defined as
- part of the description of any object which uses this
- syntax. Examples of the usage of zero might include
- situations where the Internet network address prefix
- is unknown or does not apply."
- SYNTAX Unsigned32
-
- InetPortNumber ::= TEXTUAL-CONVENTION
- STATUS current
- DESCRIPTION
- "Represents a 16 bit port number of an Internet transport
- layer protocol. Port numbers are assigned by IANA. A
- current list of all assignments is available from
- <http://www.iana.org/>.
-
- The value zero is object-specific and must be defined as
- part of the description of any object which uses this
- syntax. Examples of the usage of zero might include
- situations where a port number is unknown, or when the
- value zero is used as a wildcard in a filter."
- REFERENCE "STD 6 (RFC 768), STD 7 (RFC 793) and RFC 2960"
- SYNTAX Unsigned32 (0..65535)
-
- InetAutonomousSystemNumber ::= TEXTUAL-CONVENTION
- STATUS current
- DESCRIPTION
- "Represents an autonomous system number which identifies an
- Autonomous System (AS). An AS is a set of routers under a
- single technical administration, using an interior gateway
- protocol and common metrics to route packets within the AS,
- and using an exterior gateway protocol to route packets to
- other ASs'. IANA maintains the AS number space and has
- delegated large parts to the regional registries.
-
- Autonomous system numbers are currently limited to 16 bits
- (0..65535). There is however work in progress to enlarge the
- autonomous system number space to 32 bits. This textual
- convention therefore uses an Unsigned32 value without a
- range restriction in order to support a larger autonomous
- system number space."
