External IP
Note: A preferred way of retrieving your external IP address is to use dig.External IP
dig
curl checkip.amazonaws.com
Note: There are several alternate sites. I have used Amazon AWS as my example as retrieving your IP via curl is not considered 100% safe (i.e. the site could do more than you expect). AWS feels like it is probably one of the safer options. Other sites include: ifconfig.me, icanhazip.com, ipecho.net/plain, ifconfig.co etc.Check URL
