IP Addresses

[IS]

I have a wireless Linksys router hooked up to my desktop and a wireless
connection on my laptop.
When I post do both the desktop and the laptop have the same IP address?
What's the deal with IP addresses?
Can I read about them somewhere?

Thanks.

No. When you POST (if you mean power on Self Test) they don't have an IP
address at all, although when XP finishes loading they may have acquired
a fixed one, if the network connection is specified that way.

However typically they send a request to the router, which acts as a
DHCP server, and the router then assigns them each an IP address on the
local sub-network (192.168.1.<something> is a favourite), which they get
to keep for several days, or until they ask again. The router has it's
own IP on the same subnet (typically the router's <something> is 1). The
router also has a =different=, non-local, IP address, which is what the
WWW sees it as whenever it's connected .. so if you mean 'post' as in
'post to the NG', in both cases the post will =appear= to come from the
(non-local) IP address on the router, whichever machine actually
originated it.

What's the deal with IP addresses?
Can I read about them somewhere?

www.google.com is the best place to dig for more information than you
could possibly want.

To see what IP addresses they are actually using: start, run, cmd /k
ipconfig /all (or ipconfig /all in a CMD window). Getting the non-local
IP address assigned to the router for WWW use is not so easy, and
generally requires accessing the router viw its web interface, or using
telnet.

Each machine has it's own IP Address. If you are behind a router
though, Then the router will use NAT ( Network address translation ) so
it looks like they only have one address.

Sorry, My ride shpwed up while typing the frist reply.

To clarify my earlier post.

If you have a seprate Internet connect for each machine, They will have
different IP addresses. If you are sharing the connection through a
router, the router will use NAT to change the internal IP of each machine
to the public IP provided by your ISP, So, they will have the same IP.

Nat ( Network Address Translation ) is a function of many routers where
it receives a request packet from an internal machine and attaches the
public IP to it. When the repy packet comes in, the router knows which
machine it is for, and forwards the packets to the correct machine.

Nat also helps protect your system by dropping any packets that aren't
replies to a packet that was sent out.
