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.

|

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
|
|
that 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.
|
|
|
|
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 that provides the context. It is suggested that the
|
|
InetAddressType object be logically registered before the
|
|
object(s) that 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
|
|
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;
|
|
otherwise the applicable constraints MUST be stated in
|
|
the appropriate conceptual row DESCRIPTION clauses, or
|
|
in the surrounding documentation if there is no single
|
|
DESCRIPTION clause that is appropriate."

query multiple DNS records (e.g., A for IPv4 and AAAA for

IPv6). The order of the resolution process and which DNS

InetAddressPrefixLength ::= TEXTUAL-CONVENTION
|
|
DISPLAY-HINT "d"
|
|
STATUS current
|
|
DESCRIPTION
|
|
"Denotes the length of a generic Internet network address
|
|
prefix. A value of n corresponds to an IP address mask
|
|
that has n contiguous 1-bits from the most significant
|
|
bit (MSB), with 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 that provides the
|
|
context. It is suggested that the InetAddressType object be
|
|
logically registered before the object(s) that use the
|
|
InetAddressPrefixLength textual convention, if they appear
|
|
in the same logical row.
|
|
|
|
InetAddressPrefixLength values 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 that uses this
|
|
syntax. Examples of the usage of zero might include
|
|
situations where the Internet network address prefix
|
|
is unknown or does not apply.
|
|
|
|
The upper bound of the prefix length has been chosen to
|
|
be consistent with the maximum size of an InetAddress."

InetAutonomousSystemNumber ::= TEXTUAL-CONVENTION
|
|
DISPLAY-HINT "d"
|
|
STATUS current
|
|
DESCRIPTION
|
|
"Represents an autonomous system number that 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 ASes'. 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. Therefore, this
|
|
textual convention uses an Unsigned32 value without a
|
|
range restriction in order to support a larger autonomous
|
|
system number space."

Note that not all possible values have been assigned yet, but

DESCRIPTION

"A zone index identifies an instance of a zone of a

The zone index MUST disambiguate identical address

typically be the interface index (ifIndex as defined in the

|
|
|
|
The zone index may contain the special value 0, which refers
|
|
to the default zone. The default zone may be used in cases
|
|
where the valid zone index is not known (e.g., when a

|
management application has to write a link-local IPv6

address without knowing the interface index value). The
