Please can you clarify something about Damain Mapping

Hi again, This is for Ari really...

I have read all the instructions on the Domain Mapping plugin but am still a bit unsure about shared servers and shared IP. The instructions seem a bit ambiguous when it comes to shared IP

So, Is it possible or not to use this plugin on a shared server with shared IP? The IP directs to a landing page not related to my network site. I understand we need a dedicated IP for A records to work properly.

I am a bit reluctant to install this plugin at the moment if it may cause problems.

I will later move to the Digital Ocean server you recommended - so, will it work ok on that server.

Sorry to bother you and best regards
