This question is more of a clarification request than troubleshooting. Any insight and expertise in this area is much appreciated.
Domain mapping allows for an end user to map their TLD to their multisite blog installation.
This is generally allowed through the use of A Record in their domain registrars information.
Cname can be used, but registrars like GoDaddy, do not allow TLD example.com to be mapped to a cname, only to an IP. http://www.example.com can be mapped to a cname record, but example.com requires an IP address.
I have been desiring to have all my members map their domain address using a cname or name server to allow for flexibility in future server upgrades or migration.
The issue with this method is 2 fold.
1. Cname usually takes away MX records, so if they have email hosting through their domain registrar it gets misconfigured.
2. nameserver mapping requires I map their domain manually in my cpanel / dns. Additionally as the above, if they have email hosting through their registrar this gets misconfigured (I guess I would have to manaully remap their MX records to their email provider in this case?)
So that being said, is this the nature of domain mapping? that only A Record using the server's IP address can be used for a TLD (example.com)? and at that the IP address must be dedicated for each multisite installation.
Thank you all if you have any other advise on how to accomplish TLD mapping without IP address, and while retaining the domain registrars Mail Server configuration, let me know.
My hosting provider, although I am very pleased with, seems to also be a bit hesitant to grant me my alloted dedicated IP as them being rare and highly valued, so if I can manage to not rely on that it would be much more freeing of a configuration.
