That was my point. They don't have anything to do with outside DNS. If
you used an address that was in the outside DNS range, you would be
continually looking to the DNS table to find other PC's on your network.

Companies use theses schemes so their requests for data will not look to
the
outside DNS list. This makes the lookup a little faster, when you can
skip
the rest of the entire Internet and just look on your Intranet.

What do you mean? These reserved address ranges really don't have
anything
to do with DNS, to my knowledge.
A little confused I guess. That's what happens when you wake up with
three
inches of ice covering everything...

They are non routable. The same is true with 10.x.x.x. Companies use
theses schemes so their requests for data will not look to the outside
DNS list. This makes the lookup a little faster, when you can skip the
rest of the entire Internet and just look on your Intranet.
Hope this helps

Hi list,
I'm just curious about something. It seems that most networks use
192.168.*.* for their internal addresses. Why? It doesn't really
matter, does it? Isn't 192.168.*.* completely arbitrary? My theory on
how this came to be the norm is that MS used those addresses in some
samples in some books or something, and people started using that and it
just became the norm. But then there's that whole Internet connection
sharing feature that came out in what, W98SE? With that, the computer
that's sharing its Internet connection will be 192.168.1.1. So, I
imagine that it's coded somewhere into other OS'es to look to see if
192.168.1.1 can be used as a gateway when the user does not specify an
IP configuration. So what came first? 192.168.*.* or computers looking
to 192.168.1.1 as a gateway? Or what my real question is is why
192.168.*.*?
Thanks,
Ray at work
