Checking current external IP address with cURL

I’ve often used http://ipecho.net to print my current IP, this can be done by curling the following HTTP endpoint

$ curl ipecho.net/plain;echo
101.166.140.132

1 2	$ curl ipecho.net/plain;echo 101.166.140.132

As you can see, I ended the command with an ‘echo’ to print a new line, and only my external IPv4 address was printed.

Now, there is an alternative, with http://checkip.amazonaws.com, and also prints out the local NATed IP. Handy!

$ curl checkip.amazonaws.com
10.1.1.208, 101.166.140.132

1 2	$ curl checkip.amazonaws.com 10.1.1.208, 101.166.140.132

It’s worth noting that curling the HTTPS endpoint of checkip.amazonaws.com will only print out the external IP
