Yes--provided you remember the final . in your PTR record:

192-168-0-5  IN  PTR  www.someotherexample.com.

My pleasure.  Can't take the credit for it, though.  I've seen a friend

Delores breezed along the surface of her life like a flat stone forever 
skipping along smooth water, rippling reality sporadically but oblivious 
to it consistently, until she finally lost momentum, sank, and due to an 
overdose of flouride as a child which caused her to suffer from chronic 
apathy, doomed herself to lie forever on the floor of her life as 
useless as an appendix and as lonely as a five-hundred pound barbell in 
a steroid-free fitness center.
