Lesson Summary
Lesson 1 Configuring and Troubleshooting TCP/IP
13-25
■ Each TCP/IP host is identified by a logical IP address that identifies a computer’s
location on the network. The IP address is composed of a network ID and a host
ID. A subnet mask determines which portion of the IP address is the network ID
and which portion is the host ID.
■ A static IP address is a manually entered address. You should assign a static IP
address to selected network computers, such as the computer running the DHCP
Service.
■ Windows XP Professional can obtain an IP address automatically from a DHCP
server on the network. Using automatic addressing reduces the likelihood of
errors being introduced when configuring static addresses.
■ Windows XP Professional can assign itself an IP address using APIPA if a DHCP
server is not available. Computers enabled with APIPA can communicate only with
computers on the same subnet that also have addresses of the form 169.254.x.y.
■ Specifying an alternate TCP/IP configuration is useful when a computer is used on
multiple networks, one of which does not have a DHCP server and does not use
an automatic private IP addressing configuration.
■ Windows XP Professional includes a number of tools that you can use to troubleshoot
TCP/IP configurations. These tools include the following:
❑ Ping
❑ Ipconfig
❑ Net View
❑ Tracert
❑ Pathping
