This may be available and I just don't know how to do it. DNS is not my forte and I haven't taken the time to study the deeper mechanisms of it. But if I have 10 domains with 2 entries (.xxx and www..xxx) it would be really nice to be able to update the IP Address record for all of them at once or just specific record types. Not very clear I know, let me try and explain.
Say I want to change all of the www..xxx records from IP 126.96.36.199 to 188.8.131.52. I would be able to assign the domain (zone?) to a group and apply a template with my default IP Addresses and records. When I change the values in the template for the group, each record would be updated with the new information. If I add a new domain, I can tell it to use "Template A" for it, and the new domain would have each default entry in "Template A" created for it with the templates values (i.e. A, CName, www.*, ftp.* etc).
Implementation could either be on the Admin Site or as a possibly faster and easier fix, implement features in the API to create and update primary DNS records.
If this is already available and I am just missing it or there is some way to accomplish this same thing using various DNS record types, please let me know.
