Please Whitelist This Site? I know everyone hates ads. But please understand that I am providing premium content for free that takes hundreds of hours of time to research and write. I don't want to go to a pay-only model like some sites, but when more and more people block ads, I end up working for free. And I have a family to support, just like you. :) If you like The TCP/IP Guide, please consider the download version. It's priced very economically and you can read all of it in a convenient format without ads.

ipconfig Sample Output

You can see from the list of options in Table 308 that most of the non-viewing uses of ipconfig are actually related not to configuring a host but rather controlling the operation of protocols such as DNS and DHCP. One common use of ipconfig is to force a host to seek out a new DHCP lease, which an be done using “ipconfig /release” followed by “ipconfig /renew”.
