I have a bunch of sites that all have their own independent local DNS, i also have a centralized environment that provides services for these independent sites.
I don't want to centralize DNS in the "centralized environment" because DNS needs to remain local, but i want to be able to access things in the centralized environment via DNS without having to add entries to every one of the individual sites DNS.
so i have:
- site1.company.com
- site2.company.com
- site3.company.com
- ...
- site99.company.com
but i also have:
so I could have the local server authoritative for central.company.com, but then any single update in central.company.com is magnified by the number of sites.
I was thinking I could use RPZ to forward central.company.com requests to a name server in the centralized environment, but you don't seem to be able to do that with RPZ
I cannot just sub-domain it - because it isn't a subdomain, and if i did (make it a sub-domain) the same server would be named differently in every site (i.e. fred.central.site1.company.com and fred.central.site2.company.com) which doesn't make a lot of sense.
I am not sure if i could make each of the sites a slave for central.company.com (as well as being a master for siteX.company.com), and have a master in the centralized environment and then each of the sites would be caching the data in the site, and it would only need to be managed from the centralized master DNS server in central.company.com?
any help or pointers appreciated
thanks c
