SUMMARY
This article describes how to use the Winipcfg tool to review your currentTCP/IP network protocol settings. This can be useful when you aretroubleshooting problems, such as problems connecting to your Internetprovider.
MORE INFORMATION
To view your current TCP/IP settings using Winipcfg, follow these steps:
  1. Click the Start button, and then click Run.
  2. Type the following line in the Open box, and then click OK:
    winipcfg
Your current TCP/IP settings are displayed. To view additional information,click More Info.

NOTE: The Winipcfg display is not updated dynamically. To view changes,quit Winipcfg and then run it again.

If your IP address was dynamically allocated by a Dynamic HostConfiguration Protocol (DHCP) server, you can use the Release and Renewbuttons to release and renew the IP address.

The following sections describe the settings displayed by the Winipcfgtool.

Adapter Address:

This string of hexadecimal numbers represents the hard-coded identificationnumber assigned to the network adapter when it was manufactured. When youare viewing the IP configuration for a PPP connection using Dial-UpNetworking, the number is set to a default, meaningless value (becausemodems are not hard-coded with this type of address).

IP Address:

This is the actual IP networking address that the computer is set to. It iseither dynamically assigned to the computer upon connection to the network,or a static value that is manually entered in TCP/IP properties.

Subnet Mask:

The subnet mask is used to "mask" a portion of an IP address so that TCP/IPcan determine whether any given IP address is on a local or remote network.Each computer configured with TCP/IP must have a subnet mask defined.

Default Gateway:

This specifies the IP address of the host on the local subnet that providesthe physical connection to remote networks, and is used by default whenTCP/IP needs to communicate with computers on other subnets.

The following settings are displayed if you click More Info:

DHCP Server:

This specifies the IP address of the DHCP server. The DHCP server providesthe computer with a dynamically assigned IP address upon connection to thenetwork. Clicking the Release and Renew buttons releases the IP address tothe DHCP server and requests a new IP address from the DHCP server.

Primary and Secondary WINS Server:

These settings specify the IP address of the Primary and Secondary WINSservers (if available on the network). The WINS servers provide a servicetranslating NetBIOS names (the alphanumeric computer names seen in the userinterface) to their corresponding IP address.

Lease Obtained and Lease Expires:

These values show when the current IP address was obtained, and when thecurrent IP address is due to expire. You can use the Release and Renewbuttons to release and renew the current IP address, but this is notnecessary because the DHCP client automatically attempts to renew the leasewhen 50 percent of the lease time has expired.
