I'm trying to sort IP addresses in Excel, but I can't seem to either adjust
(custom format) the numbers to end in three digits to get it to sort properly.

For example, if I sort as-is, I get:

192.103.179.1
192.103.179.10
192.103.179.100
192.103.179.11
192.103.179.110
192.103.179.12

What I'd like to get is:

192.103.179.1 (or .001)
192.103.179.10 (or .010)
192.103.179.11 (or .011)
192.103.179.12 (or .012)
192.103.179.100
192.103.179.110

Any suggestions?
