Getting your Public IP from the Terminal

Public IPv4 addresses are assigned by NIC and belongs to CIDR blocks that are unique to the entire internet.

In this little post I show many ways to find your public IP address form the Linux terminal.

Using Curl

You can simply curl it from IP websites:

$  curl ifconfig.me

You might want to get more details (such as remote_host) with:

$ curl ifconfig.me/all

Other destination that also works: ipinfo.io/ip. Curling ipinfo.io is also great to get information about the Geographical Location of a provided IP address.

Using wget

Similary to curl:

$ wget http://observebox.com/ip -O - -q ; echo

Using dig and host

Another nice way to find the IP:

$ host -t a dartsclink.com | sed 's/.*has address //'
dig +short myip.opendns.com @resolver1.opendns.com

If you use DynDNS

Finally, if you have a DynDNS configuration:

$ curl -s http://checkip.dyndns.org/ | grep -o "[[:digit:].]\+"
