My client has a Wordpress.com owned domain name and from the looks of it, you can only change the nameserver on this instead of just pointing the A record.
Currently my server (Centos VPS w/ Parallels Plesk) is not configured with a ns so I ran through tutorials of doing this with NameCheap and Plesk and have not yet been successful:
In Namecheap I setup the "Nameserver Registration" options so that
ns1.kilrizzy.com and ns2.kilrizzy.com point to my vps's IP (I only have 1 IP address)
(After running into trouble I also have A records set for each of these pointing to my server)
In Plesk DNS settings for the domain, I have
ns1.kilrizzy.com. NS ns1.kilrizzy.com. ns1.kilrizzy.com. A 22.214.171.124 ns2.kilrizzy.com. NS ns2.kilrizzy.com. ns2.kilrizzy.com. A 126.96.36.199
Yet, when I apply these nameservers to other domains I still have no luck having them point over. Any help in debugging this would be greatly appreciated
