SUMMARY
Ipconfig.exe is a command-line tool you can use to renew and release leases obtained from a Dynamic Host Configuration Protocol (DHCP) server, and display your IP settings. This article describes these and other Ipconfig features.



MORE INFORMATION
The syntax for Ipconfig.exe is:

ipconfig [/? | /all | /release [adapter] | /renew [adapter] | /flushdns | /registerdns]

The first four switches are the same as those in Microsoft Windows NT 4.0 and earlier version. For additional information about these switches, click the article number below to view the article in the Microsoft Knowledge Base:

 * The /flushdns switch flushes the list of locally cached DNS names. When a name is resolved from DNS, the client keeps it in the cache temporarily. This option removes the cached entries.
 * The /registerdns switch allows the client to re-register its dynamic DNS entries as well as renew the DHCP lease.
 * The /displaydns switch lists the contents of your resolved DNS name cache.
