LocalAddr property

Type: Long

IP address (in network byte order) to use on the local host. This should be set before calling one of the query methods.

HexTcpQuery will bind to this address before connecting to the remote host. A value of 0 will cause the TCP/IP stack to choose the appropriate local address. The default value is 0.

This property is handy if you have a multi-homed system and wish to specify the interface for outgoing communication. In general, however, you should leave it at its default value unless you know exactly what you're doing.
