DHCP Dynamic Host Configuration Protocol. This protocol automatically
assigns an IP address for every computer on your network. Windows
95, Windows 98 and Windows NT 4.0 contain software that assigns IP
addresses to workstations on a network. These assignments are made
by the DHCP server software that runs on Windows NT Server, and
Windows 95 and Windows 98 will call the server to obtain the address.
Windows 98 will allocate itself an address if no DHCP server can be
found.
DNS server address DNS stands for Domain Name System, which allows Internet host
computers to have a domain name (such as 3com.com) and one or

addresses, so that when a domain name is requested (as in typing
"3com.com" into your Internet browser), the user is sent to the proper
IP address. The DNS server address used by the computers on your
home network is the location of the DNS server your ISP has assigned.

wireless network. You must have the same ESSID entered into the
