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."

DESCRIPTION
|

"Denotes the length of a generic Internet network address

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

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."

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

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

The zone index may contain the special value 0, which refers

where the valid zone index is not known (e.g., when a
