Retrieve External IP Address in Command Line

Method 1. Use the dig command to see your IP address from different name servers, such as opendns.com or Google’s name server.

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

Or with Google’s name server:

Method 2. We can also use the curl command and third party websites to view our external IP address. icanhazip.com will show both the IPv4 and IPv6 addresses.

To view IPv4 address:

$ curl -4 icanhazip.com

To view IPv6 address:

$ curl -6 icanhazip.com

To view IPv6 address:

$ wget -6 -qO - icanhazip.com
