I got fed up with free service from DynDNS: your record will disappear in 30 days unless you login into their site and "confirm" it. DynDNS annoys you on purpose, so you buy their "pro" service. I do not like being annoyed, and I do not see a point of paying for DynDNS service -- their value proposition is weak, as anyone can create a script that updates DNS records.

I have a website that is protected by ClouldFlare service. ClouldFlare offers an API that can be used to update DNS records, so I wrote a script for Mikrotik RouterOS that does just that.



Note that you need RouterOS v6 ( as fetch command supports https only since version 6.0rc12
