possible ways:

1. An application that is willing to accept both IPv4 and

a tcpListenerLocalAddressType of unknown (0) and

|
a tcpListenerLocalAddress of ''h (a zero-length

octet-string).
|

|
|
||
|
2. An application that is willing to accept only IPv4 or
|
||
|
IPv6 datagrams is represented by a
|
||
|
tcpListenerLocalAddressType of the appropriate address
|
||
|
type and a tcpListenerLocalAddress of '0.0.0.0' or '::'
|
||
|
respectively.
|
||
|
|
||
|
3. An application that is listening for data destined
|
||
|
only to a specific IP address, but from any remote
|
||
|
system, is represented by a tcpListenerLocalAddressType
|
||
|
of an appropriate address type, with
|
||
|
tcpListenerLocalAddress as the specific local address.
|
||
|
|
||
|
NOTE: The address type in this table represents the
|
||
|
address type used for the communication, irrespective
|
||
|
of the higher-layer abstraction. For example, an
|
||
|
application using IPv6 'sockets' to communicate via
|

IPv4 between ::ffff:10.0.0.1 and ::ffff:10.0.0.2 would

"The local IP address for this TCP connection.
|

|
|
||
|
The value of this object can be represented in three
|
||
|
possible ways, depending on the characteristics of the
|
||
|
listening application:
|
||
|
|
||
|
1. For an application willing to accept both IPv4 and
|
||
|
IPv6 datagrams, the value of this object must be
|
||
|
''h (a zero-length octet-string), with the value
|
||
|
of the corresponding tcpListenerLocalAddressType
|
||
|
object being unknown (0).
|
||
|
|
||
|
2. For an application willing to accept only IPv4 or
|
||
|
IPv6 datagrams, the value of this object must be
|
||
|
'0.0.0.0' or '::' respectively, with
|
||
|
tcpListenerLocalAddressType representing the
|
||
|
appropriate address type.
|
||
|
|
||
|
3. For an application which is listening for data
|
||
|
destined only to a specific IP address, the value
|
||
|
of this object is the specific local address, with
|
||
|
tcpListenerLocalAddressType representing the
|
||
|
appropriate address type.
|
||
|
|
||
|
As this object is used in the index for the
|
||
|
tcpListenerTable, implementors should be
|
||
|
careful not to create entries that would result in OIDs
|
||
|
with more than 128 subidentifiers; otherwise the information
|
||
|
cannot be accessed, using SNMPv1, SNMPv2c, or SNMPv3."
