Get your public IP address from command line

If you want to know your outgoing public IP address, you could go to google and search "what's my ip", google will show your IP address.

If you don't want to use google, you could just use the command line. Two ways listed below (tested in Linux and MacOS):

1st way:

$ dig +short myip.opendns.com @resolver1.opendns.com

2nd way:

$ curl ifconfig.co/

For faster access, you could just put an alias in your shell config, e.g. ~/.bashrc or ~/.zshrc:

alias myip='curl ifconfig.co/'

Next time you can just open your terminal then run:

$ myip
$ 67.83.127.63

We can also use other third-party services to query the public IP on our host:

$ curl ifconfig.me
$ curl icanhazip.com
$ curl icanhazip.com
$ curl ipecho.net/plain

And we can use the host command to resolve OpenDNS service on our host to get the current public IP address:

host myip.opendns.com resolver1.opendns.com | grep "myip.opendns.com has" | awk '{print $4}'
