Yeah, sorta. In the db.212.187.0 I have '39 IN PTR nisser.com.'. Yet that answer will only be given by my NS. Meaning a process more or less like I decribed is being followed. Which? Well, my copy of DNS and BIND is 10 cm out of reach. A small step for mankind, but a big step for a programmer :). Roelof PS not so long ago there was an article published about setting ones DNS op so that it would allow reverse resolving by the target machine. Believe it was in one of the BSD zines with a titel that included 'classless'. -- Home is where the (@) http://eboa.com/ is.
