| I have a small network of computers that are all connected to a network. I
have no DHCP server what so ever on the network. I connect to the internet
using a cable modem and a router. I have 20 computers connected to the router
(eventually through switches and whatnot). Is it correct to assume that on the
internal Network my computers use Automatic Private IP Addressing for the
internal LAN. Then The cable modem obtains a dynamic IP from the cable company
for all of the computers to use on the internet. Or does the router (after it
obtains the dynamic IP from the cable company) just create dynamic IP's for the
computers to use because it uses the NAT feature. If I have worded this badly
I am sorry. Thanks for any help in advance.

| Your router is probably the DHCP server. Do you know how to check what IP's
you computers are using? If they are using 169.154.xxx.xxx, your using auto
priv addressing (but this isn't likely....you wouldn't be able to access the
internet through the router.) You probably have a 192.168.xxx.xxx number or
something other (depending on the router settings).

My router gets an IP address through DHCP from the cable company, I know that.
What I am curious about is the LAN. Since I don't have a DHCP server on the
local LAN does this mean I definitely use automatic private IP addressing or is
there a chance that my router assigns IP address using its NAT feature. I know
my router has NAT. There are a set of specific IP addresses set aside to be
used on internal private networks just for this. I hope this makes it more
clear.

Since your router is giving out IP addresses from an address pool, it is a
DHCP server....this is all I was saying in my last post. You are NOT using
auto priv IP addressing...internet would not be working.
What is your question? Are you using auto priv addresses? :most likely -
no. Is your router grabbing IP from cable co? - Yes. Is your router
assigning IP's to your network computers? - Yes, most likely. Does your
router us NAT? Yes. Is your router acting as a DHCP server? Yes.

Ok, I think I am understanding what you meant now. This wasn't a
troubleshooting issue. I was just curious as to how it worked. I am always
appreciative of anyone willing to try and share knowledge. Thanks.

| Your nat device probably has a dhcp server built in and can provide ip
addresses for your local network. If your ip addresses are 192.168.x.x you
are probably getting ip addresses from your NAT router otherwise you are
probably getting an Auto-config ip if you are running Windows 2000 or
higher.

| Your statement is incorrect. The router IS a DHCP server. It assigns
(if you let it) all TCP/IP parameters (not only IP address but subnet
maks, default gateway, etc.) to all of the computer connected to it on
the LAN side.

| Did you assign each computer it's own ipaddress or did you just plug them in
and it did it it's self.
Do you know what make and model you router is? maybe we can tell you if that
router supports DHCP.
