Useful if you're a developer and are either testing with different networks or have to look up your IP address a lot
I very often go to google and search for "my ip address" and copy it. With Ip Man I have it in hand in case I need it.
I had a terminal shortcut command setup to quickly fetch the local lan address when I have to test a website hosted in the laptop on my phone. This tool makes it even easier without having to open terminal at all.
Neat. Simple. Elegant.
You can Option+Click on your wifi icon and get most of this information, but copying feature is quite handy
Having to change often network and testing lot of sites hosted locally from smartphone is great to have always ready all the info about my local/public ip addresses.
