I have set up a classic hybrid network between my on prem network and Azure network. The azure net has AD and file servers and the cloud services in which they reside are configured with my on prem DNS servers and all servers work fine.
My on prem DNS servers are forwarding DNS requests properly for zones/hosts that they do not own, like google.com, cnn.com, etc... but they are also trying to resolve a number of hostnames that include stuff like:
***************
wpad.cs-aaaa.j9.internal.cloudapp.net |
wpad.cs-bbbb.j6.internal.cloudapp.net |
wpad.cs-cccc.j10.internal.cloudapp.net |
*.l.google.com |
outlook.office365.com |
sl1.sal.avaya.com |
isatap.cs-aaaa.j9.internal.cloudapp.net |
isatap.cs-cccc.j10.internal.cloudapp.net |
teredo.ipv6.microsoft.com.nsatc.net |
***************
where aaaa, bbbb, cccc are my cloud service names.
These requests are being sent to my external DNS resolvers, but I don't understand why or which server or part of Azure is making this request. It seems like those are Azure internal names that should be resolved internally and not by my on prem DNS or their external forwarders, neither of which can resolve the requests.
Can anybody help me understand why this is occurring or how to rectify it?
Thanks,
Brit
