Domain DNS settings for Domain Mapping plugin on Multisite

I’m having troubles getting the Domain Mapping plugin to work.

I have installed and configured the plugin.

I have given the site a unique IP address on my VPS. (Did I need to do that?)

I have set the nameservers to resolve to the VPS

(ns1.VPS.com, ns2.VPS.com)

I set the IP address in the A record to the new IP address I assigned the site.

It’s been more than 72 hours since I changed the DNS… still not seeing anything.

I have enabled support access on the site in case the issue is there… however I’m pretty sure the issue is on the domain name side. I’ve got a screenshot of the domain manager DNS settings page if that would help.
