![]() ![]() To specify an adapter name, type the adapter name that appears when you use ipconfig without parameters. This parameter disables TCP/IP for adapters configured to obtain an IP address automatically. Sends a DHCPRELEASE message to the DHCP server to release the current DHCP configuration and discard the IP address configuration for either all adapters (if an adapter is not specified) or for a specific adapter if the adapter parameter is included. The DNS settings in the advanced properties of the TCP/IP protocol determine which names are registered in DNS. ![]() You can use this parameter to troubleshoot a failed DNS name registration or resolve a dynamic update problem between a client and the DNS server without rebooting the client computer. Initiates manual dynamic registration for the DNS names and IP addresses that are configured at a computer. During DNS troubleshooting, you can use this procedure to discard negative cache entries from the cache, as well as any other entries that have been added dynamically. The DNS Client service uses this information to resolve frequently queried names quickly, before querying its configured DNS servers.įlushes and resets the contents of the DNS client resolver cache. Adapters can represent physical interfaces, such as installed network adapters, or logical interfaces, such as dial-up connections.ĭisplays the contents of the DNS client resolver cache, which includes both entries preloaded from the local Hosts file and any recently obtained resource records for name queries resolved by the computer. Syntax ipconfig ] ] ] ] ]ĭisplays the full TCP/IP configuration for all adapters. ![]() Used without parameters, ipconfig displays Internet Protocol version 4 (IPv4) and IPv6 addresses, subnet mask, and default gateway for all adapters. Displays all current TCP/IP network configuration values and refreshes Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS) settings. ![]()
