It’s quite useful to have at your fingertips the option of getting your public IP address. Here I will give you various commands to get the IP. Note not all of them have IPv6 service, so only works with IPv4.

IPv4 & IPv6

If you have a connection to the Internet with IPv6, by default, it will be used this interface. However you could force the IPv4 use just adding the -4 option to the curl command. Something like curl -4 ip.sb.

curl icanhazip.com

curl ifconfig.co

curl ip.sb

curl json.myip.wtf

Just IPv4

This services only works with IPv4, but it could be enough for you, (Not for me 😄)

curl ipinfo.io

curl checkip.amazonaws.com

curl checkip.dyndns.org

curl ip-api.com/json
