Infoblox dns resolution in hybrid environment

balumunikumar

Hi team,

I have a hybrid setup from on-prem to Azure.

I have private DNS zone (azure-api.net)in Azure and Private DNS resolver . I setup a forward zone in on-prem infoblox named azure-api.net and configured forwarder as Azure private DNS resolver inbound ip. Now on-prem systems able to resolve the records which exist in private DNS zones in Azure , but they are unable resolve public DNS records with azure-api.net

Could you help me to resolve this.

The "fallback to internet" setting for Azure DNS Private Link zones should solve this. https://learn.microsoft.com/en-us/azure/dns/private-dns-fallback. It let's you relsove the private endpoints via the private zone, then allows for recursive resolution of endpoints not in your private zone.

You have two options:

1. Enable Azure to publicly recurse queries for azure-api.net that its local resolver cannot resolve locally. https://learn.microsoft.com/en-us/azure/dns/private-dns-fallback
2. Use local RPZ on NIOS to redirect individual FQNDs to Azure Private DNS resolver as required (so everything else resolves using public DNS)
