UDP-MIB Table View

A table containing information about this entity's UDP
endpoints on which a local application is currently
accepting or sending datagrams.
          
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 use
InetAddressType ipv4(1).
          
Unlike the udpTable in RFC 2013, this table also allows
the representation of an application that completely
specifies both local and remote addresses and ports.  A
listening application is represented in three possible
ways:
          
1) An application that is willing to accept both IPv4
   and IPv6 datagrams is represented by a
   udpEndpointLocalAddressType of unknown(0) and a
   udpEndpointLocalAddress of ''h (a zero-length
   octet-string).
          
2) An application that is willing to accept only IPv4
   or only IPv6 datagrams is represented by a
   udpEndpointLocalAddressType of the appropriate
   address type and a udpEndpointLocalAddress of
   '0.0.0.0' or '::' respectively.
          
3) An application that is listening for datagrams only
   for a specific IP address but from any remote
   system is represented by a
   udpEndpointLocalAddressType of the appropriate
   address type, with udpEndpointLocalAddress
   specifying the local address.
          
In all cases where the remote is a wildcard, the
udpEndpointRemoteAddressType is unknown(0), the
udpEndpointRemoteAddress is ''h (a zero-length
octet-string), and the udpEndpointRemotePort is 0.
          
If the operating system is demultiplexing UDP packets
by remote address and port, or if the application has
'connected' the socket specifying a default remote
address and port, the udpEndpointRemote* values should
be used to reflect this.
