There are five buildings in this facility, and seven more in Northern
California that form this division. They're far enough apart that we
have separate staff for each campus. Then there is corporate in New
York, but our IP ranges are shared between facilities around the world.
As long as we stay within the guidelines from corporate, we're pretty
much master of all we survey.

Up until about 2002, we still had floppy drives in all systems, and
that meant we carried Tomsrtbt (and similar for non-Linux) in the shirt
pockets. However, corporate says... and that was basically the end of
removable media drives on workstations, and that trickled down into our
servers. The hardware types who do installs and repairs have what
amount to be portable drives. We're very dependent on networking, so
installs basically consist of popping the hood to inspect things and
do an inventory, connecting a bootable CD, and doing a network install.
As most of the working systems are not in space where it's convenient
to work on, if the system can't be brought up from the console, it's
at least temporarily replaced, and repaired in a shop area with the

The old /8s and /16s that were assigned/allocated long ago still exist,
and that accounts for a significant amount of address space. 18.104.22.168
was the last /8 allocated (to comcast in 2005) and before that, you're
back in 1991. /16s are more common - there's about 10000 of them and
just under 1600 of those were allocated/assigned since 1/1/2000, but
that's merely a reasonable chunk size that's not to hard to justify.
See RFC2050, but also see RFC1917 for the other side of the coin. IPv4
address space isn't unlimited, and this was recognized as far back as
RFC1366 in 1992.

Obviously, you aren't the right person to be working for us. But that
should not be a surprise, as there is no "one size fits all" positions.
