I have successfully installed domain mapping plugin for my multisite http://www.iwebsite.ph. But when I tried to map one subdomain site1.iwebsite.ph to workimprovements.com it does not work.
On site1.iwebsite.ph under Tools > Domain Mapping I'm entering "workimprovements.com" and clicking Add button. The page refreshes but nothing seems to happen workimprovements.com was not added.
I have already added a custom DNS A record and have 18.104.22.168 as its value.
However there is also a Non-editable DreamHost DNS record and the A record has the value 22.214.171.124
Does this mean I need a dedicated IP from my host? which is Dreamhost. I have VPS with them.
I checked the IP 126.96.36.199 and its not resolving to my WPMU site.
Thanks for your help.
