Mikrotik script for other manage DNS and domain name

Hello everybody,
Seeking for advise regarding dynamic DNS script. We currently using Mikrotik 751U-2HnD, current firmware version 3.02.
We will use this Mikrotik AP for our customer. There will be 500 of sub domain where these sub domains is to be used to access a web server via internet. We would like to have function like Dyn Remote Access but the team decided to purchase Dynect Manage DNS with a domain name.

We would like to check on the script that needs to be apply at the Mikrotik. Can we use the same Mikrotik script that we get from below link:
http://wiki.mikrotik.com/wiki/Dynamic_DNS_Update_Script_for_dynDNS

Or, is there any different script that we have to use?

Hope to hear from you soon.

Thanks in advance

Regards

I am also using DynECT.

Can anyone confirm which script to use with DynECT?
