HP Digital Home Networking - Using Ipconfig for the Ethernet Adapter

Introduction
Ipconfig is a command line utility included with Windows. This utility provides you with diagnostic information related to TCP/IP network configuration. Ipconfig also accepts various Dynamic Host Configuration Protocol (DHCP) commands, allowing a system to update or release its TCP/IP network configuration. Follow the steps below to run the Ipconfig utility.
  1. Click Start, and then Run.
  2. In the Open field, type cmd and click the OK button. The command prompt window will appear.
  3. At the command prompt, type ipconfig /all.
  4. Your network settings will be displayed.
  5. To release your current IP address, type ipconfig /release at the command prompt. A confirmation will appear indicating that your IP Address has been released.
  6. To obtain a new IP address, type ipconfig /renew at the command prompt. Your network settings with the new IP address will appear.
     note:
    The /renew parameter is available only if the adapter is configured to obtain an IP address automatically.
  7. At the prompt, type exit and click OK.
Syntax
The Ipconfig utility can also be run with various other syntaxes. The syntaxes and explanation of the syntax parameters are as listed below.
/all
Displays the full TCP/IP configuration for all adapters. Without this parameter, ipconfig displays only the IP address, subnet mask, and default gateway values for each adapter. Adapters can represent physical interfaces, such as installed network adapters, or logical interfaces, such as dial-up connections.
/renew [Adapter]
Renews DHCP configuration for all adapters (if an adapter is not specified) or for a specific adapter if the Adapter parameter is included. This parameter is available only on computers with adapters that are configured to obtain an IP address automatically. To specify an adapter name, type the adapter name that appears when you use ipconfig without parameters.
/release [Adapter]
Sends DHCPRELEASE message to the 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. This parameter disables TCP/IP for adapters configured to obtain an IP address automatically. To specify an adapter name, type the adapter name that appears when you use ipconfig without parameters.
/flushdns
Flushes and resets the contents of the DNS client resolver cache. 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.
/displaydns
Displays 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. The DNS Client service uses this information to resolve frequently queried names quickly, before querying its configured DNS servers.
/registerdns
Initiates manual dynamic registration for the DNS names and IP addresses that are configured at a computer. 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. The DNS settings in the advanced properties of the TCP/IP protocol determine which names are registered in DNS.
/showclassid Adapter
Displays the DHCP class ID for a specified adapter. To see the DHCP class ID for all adapters, use the asterisk (*) wildcard character in place of adapter. This parameter is available only on computers with adapters that are configured to obtain an IP address automatically.
/setclassid Adapter [ClassID]
Configures the DHCP class ID for a specified adapter. To set the DHCP class ID for all adapters, use the asterisk (*) wildcard character in place of adapter. This parameter is available only on computers with adapters that are configured to obtain an IP address automatically. If a DHCP class ID is not specified, the current class ID is removed.
/?
Displays help at the command prompt.
