# DDNS Cloudflare - KeepUpIP

|
The script checks the current external IP based on defined websites.
|
|
In case of a change in the external IP, it updates the CloudFlare service using a dedicated API.
|
|
It requires providing 'api_key' and 'dns_zone' IDs.
|
|
Parameters, such as the number of logs set to 10k lines, can be customized.
|
|
The frequency of execution should be defined in cron/schedule.
