This page discusses simple tips and tricks that I have discovered while playing around with networking tools and concepts

While some might not be useful or applicable to all users and situations, it can potentially provide some shortcuts.

Retrieve public IP address

$ curl ifconfig.me

# alternatively, to allow the output to be displayed properly
$ curl ifconfig.me && printf '\n'
xxx.xxx.xxx.xxx

This simple command sends a HTTP GET request to the host ifconfig.me, which simply returns the source IP address. There are some other useful flags provided, visit https://ifconfig.me/ to learn more.

This command can be useful to discover the public IP address of a machine behind any types of connections such as a campus or VPN.
