IP Man is a simple Mac menu bar app displaying your public IP at any time. Easily and quickly copy/paste it by clicking it or by using the shortcut cmd+i.
IP Man also provides you, with the same ease, your WLAN and ethernet addresses.
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.
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.
