The default is to display only the IP address, subnet mask and
default gateway for each adapter bound to TCP/IP. For Release
and Renew, if no adapter name is specified, then the IP address
leases for all adapters bound to TCP/IP will be released or
renewed. For SetClassID, if no class id is specified, then the
classid is removed. Examples
To get your computers local network IP address, subnet mask, and default gateway typing ipconfig alone will display this information as shown below. Keep in mind this is only your local network information. If you're trying to determine your IP address used on the Internet we suggest viewing our system information page. ipconfig Ethernet adapter Local Area Connection:
