Reference Type: Supported, Category: IP Address Functions, ICR#: 5844
The $$FORCEIP4^XLFIPV extrinsic function converts an IP address (either IPv4 or IPv6) into an IPv4 address in a standardized format consisting of four decimal numbers, each in the range
0 to 255. For example:
001.99.001.9
$$FORCEIP4^XLFIPV(ip)
ip:
|
(required) IPv4 or IPv6 address (string; in quotes) to be converted.

An IPv4 address in “nnn.nnn.nnn.nnn” notation if the input address is valid and has an IPv4 equivalent.
-
The NULL address “0.0.0.0” if the input address is invalid.
-
The NULL address “0.0.0.0” if an IPv6 address is input that does not have an IPv4 equivalent.
