Updating your IP in a Linux environment using CURL

An example update using CURL:

curl -H 'Authorization:Basic $AUTHSTRING' "https://nic.changeip.com/nic/update?&hostname=example.com&ip=1.2.3.4"

Replace $AUTHSTRING with a base64 encoded value of your username and password in an authentication header.

We would suggest using this form to generate the value (although we do not author nor support it):
