I gathered that even though I'm unaware of anyone presently going beyond 
0.0.255, that there was a good chance someone would eventually, which is 
why I decided to check only for a value starting with the four

Oh, good! Thanks for the pointer.  And it's written by John Levine, 
which I find reassuring.  It does appear that testing for "127." is 
about the best I can do with this.
