Bind an IP address

This option is used when two dissimilar applications need to use the same port. You indicate that one application will use the port for data received on a specific IP address. Another application can use the same port, but for data received on a different IP address.

The most common usage of this is with the TN3270 server and the TELNET server. Both are defined by the IETF to use well known port 23. To allow for both to properly function using port 23, you would need to enable the "Bind an IP address" option for one of the two servers.

This option is not valid for port ranges.

This option is available for UDP applications. However, a UDP port cannot be reserved for two different job names. Therefore, the usefulness of this function for UDP applications is limited.

The internet address must be specified in dotted decimal notation, in which a 32-bit internet address is represented as four decimal numbers, one for each 8 bits, separated by dots (periods). Each of the four decimal numbers is greater than or equal to 0 and less than or equal to 255. For example:

00001010  00000001  10110100  11111110  a 32-bit address
10              1                180            254            dotted decimal notation (10.1.180.254)
