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.

If you want to use this site for free, I'd be grateful if you could add the site to the whitelist for Adblock. To do so, just open the Adblock menu and select "Disable on tcpipguide.com". Or go to the Tools menu and select "Adblock Plus Preferences...". Then click "Add Filter..." at the bottom, and add this string: "@@||tcpipguide.com^$document". Then just click OK.

Thanks for your understanding!

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”.
