Let ( [ temp1 = Int(number / (256 * 256 * 256)); tempLong = number - (temp1 * 256 * 256 * 256); temp2 = Int(tempLong / (256 * 256)); tempLong = tempLong - (temp2 * 256 * 256); temp3 = Int(tempLong / 256); tempLong = tempLong - (temp3 * 256); temp4 = Int(tempLong); tempLong = tempLong - temp4 ]; temp1 & "." & temp2 & "." & temp3 & "." & temp4 ) Click to copy

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.

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? Thanks
