I am wondering if someone can advise me on backup DNS techniques? I have bascially got two servers, one hosted with EV1 and a backup hosted on a business broadband connection. I have setup a backup mailserver on the backup server, along with backup DNS. I have MX records in each domain with a priority of 10 for my primary mail server and 30 for my backup.
My question is this:
Is it possible to prioritise other DNS records? For example, for one of my domains, the name servers are:
Where "ns2.mynameserver.net" is my backup DNS server. For some reason however, some ISPs are going to "ns2.mynameserver.net" for resolution first?
I'd like to be able to put a "www" host entry for all domains in my backup DNS pointing to itself with a standard 'SORRY, THIS WEBPAGE IS CURRENTLY UNAVAILABLE' message but obviously can't if some request are going to resolve usin the backup DNS first.
Thanks in advance
