While it’s easy to get an IP address from popular websites such as whatismyip.com, it’s not often friendly to a context where you might need to get your IP address for command line tools.
In order to grab your IP address via the command line, there’s a page on a site called ipinfo.io/ip which only contains body content corresponding to your IP address. The easiest way to fetch that data is with the
curl
command (should be available on both Windows and Linux).curl ipinfo.io/ip
It may also be beneficial to add this to your
.bashrc
or.aliasrc
on Linux systems with something like
alias myip="curl ipinfo.io/ip"
Now you have an easy way to grab your IP address from the command line!
If you’re connected to the internet via a local network such as a router or modem,
ifconfig
will give your local IP address, not your public IP address. Instead, the methods in this post and comments all discuss ways to get your public IP address. It usually requires contacting an external server that you trust and asking them “which IP address did I just contact you with?”
