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."
SYNTAX OCTET STRING (SIZE (0..255))
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."
