Same internal and external zone

[Sarath]

Hi All,

I have a situation where the same domain for example xyz.example.com is both internal and external.

The internal xyz.example.com is on an internal host (private address ) which is the default DNS server for all internal hosts (all hosts use this DNS server in their resolve.conf ) And the external xyz.example.com is on another public ip server (aws route 53 ).

The problem is i have a hostname for example xyz.xyz.example.com which is on the public DNS server..and my local network hosts cannot
Resolve that hostname which is on the public DNS server (route 53)

The reason is because local DNS server is also authoritative for xyz.example.com, and as it does not find xyz.xyz.example.com on the local zone it gives no reply..

I cannot add the record of xyz.xyz.example.com on my local DNS server (which is bind )because that host is DNS load balanced using route 53 health checks..

Is there any other solution to get this done in bind, like adding a cname also won't work..

Please let me know if there is some solution or workaround for this.... 

Thanks 
Sarath
