Ok what does this mean? that something should respond to a ping or not? I thought the reason these numbers were reserved was that everyone(routers) were supposed to ignore them if they ever appeared on the internet. So if I do traceroute and someone in the 204.157 domain is responding does that mean something is a miss? or that they were given the numbers... I have been telling folks to use those reserved numbers for their private networks because they should/would never appear on the net. I guess I was wrong :-( Oh well, lost count of my mistakes long ago :-) Jim Leppek > From owner-freebsd-questions@freefall.cdrom.com Tue Apr 18 16:23:36 1995 > From: terry@cs.weber.edu (Terry Lambert) > Subject: Re: PPP and dynamic IPs drifting a little > To: jleppek@suw2k.ess.harris.com (James Leppek) > Date: Tue, 18 Apr 95 13:53:49 MDT > Cc: freebsd-questions@FreeBSD.org > X-Mailer: ELM [version 2.4dev PL52] > Sender: questions-owner@FreeBSD.org > > > Speaking of IP's I was responding to this mail and recalled > > the words of wisdom in the /etc/hosts file about selecting > > private IPs from a set of reserved numbers that are never > > to appear on the net and getting valid numbers if > > you are on the net.
