+            The value of this object can be represented in three

+
+            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
