Converts a IP Long number to a real usable IP address.

This is used by a lot of php/mysql programmers as a IP Long number uses less space in the database, being a number (int) instead of a text (varchar).
Indexing is faster.

This function converts the number (int) back to a real IP addres, that can be used on the web or servers.

Note: these functions are not guaranteed or supported by Please contact the individual developer with any questions or problems.

This is my Custom Function and I want to edit it


Thanks, this may be just what I need.

Is there one to do the opposite, just in case I need to go back from an IP to an integer?
