I have seen several of my client's HP3000's configured with an IP address
of 192.1.1.1, and I seem to recall seeing somewhere an NMMGR manual (on
paper) which used 192.1.1.1 as an example of what to put into the IP
address field when configuring the LAN. A lot of people, new to networking,
simply used this address because they didn't know any better.

The current NMMGR manuals on docs.hp.com use 192.191.191.009 as an example,
which I am not sure is any better.
