[tac_plus] regular expression for IP address

Apparently, though unproven, at 19:43 on Thursday 27 January 2011, Floyd, 
Devin did opine thusly:

The second one works, it's what I use on 4.0.4.18 and 4.0.4.19

Syntax exactly the same as your example below. run tac_plus with -d8 -d16, the 
logged output should tell you why it's failing
