There is nothing that precludes you from having the same zone on different DNS servers. You make each "authoritative" so that any look up that hits that DNS server gets that server's records. You can then have separate entries for some items and the same for others.
We do that here with at least one domain where our internal Windows servers keeps track of internally USED IPs and our external facing DNS servers keep track of externally reachable IPs. For the few records where we want to have the internal user use the externally reachable IP we just add the record to both. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Joshua Smith Sent: Friday, February 14, 2014 1:03 PM To: Sarath Cc: [email protected] Subject: Re: Same internal and external zone Can you not delegate xyz.xyz.example.com to route 53 on your internal name server? -- Josh Smith KD8HRX Email/jabber: [email protected] Phone: 304.237.9369(c) Sent from my iPhone. > On Feb 14, 2014, at 12:53 PM, Sarath <[email protected]> wrote: > > 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 > ------------------------ > Powered by BigRock.com > > _______________________________________________ > Please visit https://lists.isc.org/mailman/listinfo/bind-users to > unsubscribe from this list > > bind-users mailing list > [email protected] > https://lists.isc.org/mailman/listinfo/bind-users _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list [email protected] https://lists.isc.org/mailman/listinfo/bind-users Athena(r), Created for the Cause(tm) Making a Difference in the Fight Against Breast Cancer --------------------------------- CONFIDENTIALITY NOTICE: This e-mail may contain privileged or confidential information and is for the sole use of the intended recipient(s).
