Lesson 1 Configuring and Troubleshooting TCP/IP<br />

13-15<br />

Figure 13-7 Use the Ipconfig /all command to display a complete TCP/IP configuration.<br />

Note You must run Ipconfig from a command prompt. If you try to execute it by using the<br />

Run command on the Start menu, the command window will close before you have a chance<br />

to read the information that is displayed.<br />

Additional Ipconfig options include the following:<br />

/release Releases DHCP-supplied configuration information<br />

/renew Renews DHCP-supplied configuration information<br />

/flushdns Purges the local DNS cache (the area of memory that stores recently<br />

resolved names so that the client does not have to contact the DNS server each<br />

time)<br />

/registerdns Renews DHCP-supplied configuration information and registers the<br />

DNS name to IP address information with DNS<br />

/displaydns Displays the contents of the local DNS cache<br />

/setclassid Provides for the configuration of DHCP user classes, which can control<br />

the way IP addresses are assigned<br />

<strong>Exam</strong> Tip Understand the various options available with the Ipconfig command. In particular,<br />

you should remember what /renew, /release, and /flushdns do.
