tcp/ip addresses

by Ann777 In reply to tcp/ip addresses

The network that is picking up ip addresses is doing so from a device acting as a DHCP server. ( see http://www.dhcp.org/ for more info )

This "device" can be a "server" or a broadband cable/dsl router. If DHCP is setup on a server then there'sa place within that service that allows administrators to setup a scope (or range) of ip addresses to use.

When you first start a client computer with a nic within, and within the network properties in control panel you've set the computer to obtain an ip address automatically, the computer will look for a DHCP server. If no DHCP server is found on the network, Windows will assign 169.254.x.x with a subnet mask of 255.255.0.0. If a DHCP server is found, then the request for an ip address is heard and a potential ip address is assigned within that scope.

Answer 1 is correct but to give more info;

From a Windows NT / 2K / XP machine, go to a command prompt (C&gt

Type IPCONFIG /ALL there will be an entry for your DHCP Server

Windows 9x = WINIPCFG

Type TRACERT XXX.XXX.XXX.XXX replace the Xs' with the IP number of the DHCP Server that you found with the last command.

You will then have the name and IP number of your DHCP Server. Just a case of tracking it down after that.

Hope this helps.
