No IP for Wordpress Multisite

Hi there!

I would really like to use the domain mapping tool, to allow each site in my wp 'network' to use a different domain, however, I can not use an IP address for the wp 'network'. This is because my wp 'network' is actually sat behind a load balancer (Amazon's Elastic Load Balancer) which is only accessible via a specific domain name (something like: The actual IP of the load balancer changes regularly.

Normally this should be fine, because I would just use a cname alias instead of an A record in the DNS zone. Is this possible with the fantastic domain mapping plugin, I really hope so!

Thank you for your time helping me!

All the best,
Laurence Pettitt
