Cloudflare Dynamic DNS

Dynamic IP? No Problem! Keep your Domains in check!

Quickly update DNS records for one or many domains names to the current external public IP address.

Perfect for any HomeLab, SelfHosted web server, RaspberryPi, NGINX reverse proxy servers and whatever else you want to host.

Backup your Cloudflare DNS configuration before blindly using these tools!

Usage

Edit UpdateAll.sh or UpdateSingle.sh and fill in the required info:

# CloudFlare Account Details
auth_email="EMAILADDRESS"
auth_key="AUTHKEY"

UpdateAll.sh - Multiple domains can be bulk updated, define them here.

zone_names=("DOMAINNAME.COM" "DOMAINNAME2.COM" "DOMAINNAME3.COM")

UpdateSingle.sh - A single domain you want to manage.

zone_name="DOMAINNAME.COM"

Nice work, Let's do it 👍

Hmmm, Amazon has closed it's doors? Update the IP check from https://checkip.amazonaws.com to an alternative location.

Mac OS?

You are unfortunately missing a few key features from grep!

Update grep with Homebrew 😇

brew install grep --with-default-names
grep --version
grep (GNU grep) 3.1
