About this site

This is a web-based alternative to the now-deprecated Network Utility tool from Mac OS. Network Utility was a friendly front-end to terminal commands frequently used when working with domain names, network etc. Because this is a regular website, you can access it in pretty much any browser on any operating system.

To have a shortcut to this site, bookmark it or visit us often, and eventually your browser will start suggesting our address as soon as you type 3 into address bar. Alternatively, if you're on a Mac, you can create a dock icon: Use Safari web apps on Mac.

If you prefer a desktop program

You can install Whatroute by Bryan Christianson or Neo Network Utility by DEVONtechnologies.

Finally, if you're on Ventura, Monterey, or Big Sur, you can follow the osxdaily.com instructions to try and restore the original.
