I dont want to pay my ISP extra for static ip address, so i wrote this script to change my CF domain accordingly. It checks for IP changes on main pppoe out every 3 minutes, and updates CF record if something has changed.
First of all, you need to create your home domain (lets say home.example.com) via cloudflare console or API.
curl -X POST "https://api.cloudflare.com/client/v4/zones/MY_CF_ZONE_ID/dns_records" \
-H "X-Auth-Email: [email protected]" \
-H "X-Auth-Key: MY_API_KEY" \
-H "Content-Type: application/json" \
--data '{"type":"A","name":"home.example.com","content":"10.10.10.10","ttl":{},"priority":10,"proxied":false}'From json response extract result.id value (for example, pipe output of curl to curl ... | jq -r ".result.id").
Script variables you need to change::
-
domain : domain you want to update
-
theinterface : your interface that is pointing to internet
-
cfmail : cloudflare mail
-
cfapikey : cloudflare api key
-
cfzoneid : cloudflare zone id
-
cfdomainid : cloudflare domain id shown above.
This script works by updating A record with PUT request using fetch microtik command.
