When setting up Windows NT and configuring the TCP/IP, what address should I input for the card? The computer is a PDC with 7 Windows 95 clients. My question is what numbers do I need to input. It lists 2 adapters, the network card and the wan adapter. Does it matter what numbers I put in, I entered all one's.
Thanks,

Chris

You have one consideration here...  Do you want to connect to the Internet or another network which is connected to the Internet?

There is a rule - One machine, one IP address.  If there were two machines on the same network (don't forget the Internet is one large network) witht the same IP address ther would be a conflict and each machine would win the conflict in the order in whcih their IP's are presented to a particular network segment.  

If you connect to the Internet you will have to speak to your ISP and have them assign you  a block of IP addresses and a subnet mask.

If you do not wish to connect to the Internet you can use a different block of IP addresses specifially set aside for stand-alone networks:

Read the following and implement it on your Network, you should not choose the numbers which you have now.

Address Allocation for Private Internets
RFC 1918 requests that organizations make use of the private Internet address space for hosts that require IP connectivity within their enterprise network, but do not require external connections to the global Internet. For this purpose, the IANA has reserved the following three address blocks for private internets:

10.0.0.0 - 10.255.255.255 (10/8 prefix)

172.16.0.0 - 172.31.255.255 (172.16/12 prefix)

192.168.0.0 - 192.168.255.255 (192.168/16 prefix)

Here are two resources on IP addressing:

The adapters come up in the NT setup. So you are saying that I could enter in the following number 10.255.255.255? Also what number should I enter for the wan adapter. The Internet is not an issue for the server, but the workstations access the Internet. Using individual AOL accounts.

A general rule in TCP/IP is no "all 0's" and no "all 1's".

The only time you should use all ones is for a complete class subnet such as a class C network where your mask would be 255.255.255.0.

10.0.0.0 - 10.255.255.255 (10/8 prefix)

If you choose this range the consider the following:

it is typical for a network to reserve the lowest IP's for gateways, routers, switches, etc.  So you may choose to place your router at an address 10.0.0.1 and yor servers at addresses after this like 10.0.0.10 and so on.  All workstations would be placed at a range well above this, 10.0.0.25 and up.
