difference between forward and reverse lookup dns query

Azure DNS Private Zones (An internal DNS Service in Azure which can provide DNS lookup within a virtual network, allows you to manage records in Azure).DNS Proxy (Having a virtual machine or service which can provide DNS services for services in Azure but authoritative DNS servers are outside of Azure).DNS Server running IaaS (Provides full flexibility, but requires that you have virtual machines that running to deliver DNS services).

Azure built-in DNS (Does not provide any ability to change or update record).When it comes to providing DNS Servces in Azure, there are a couple of options. You can also change the DNS Server scope on a virtual network, but this will not affect other virtual networks that are peered or otherwise connected to the virtual network using VPN or ExpressRoute. This IP address is an internal VIP address by Microsoft (Which is only available internally from wtihin Azure) ( Traffic should not be blocked to this IP address, this address is static and will not change) When you setup a virtual machine within this VNET it will automatically get assigned IP by a DHCP service and DNS lookup services by an internal IP address 168.63.129.16. Now as you might know within each subnet Azure also reserves the first 4 IP addresses to Azure related services, so for instance if we have a 10.0.0.0/16 subnet the x.x.x.2, x.x.x.3: Is reserved by Azure to map the Azure DNS Server IPs to the VNet space. When setting up a virtual network it will by default use the internal Azure DNS service. How does DNS lookup work within Microsoft Azure?Īzure provides internal name resolution for VMs and role instances (including app services) for all services that reside within a virtual network. With the latest addition of DNS Proxy to Azure Firewall ( ) and looking at some of the questions I get on this blog I guess it was time to write a bit about how DNS lookup works within Microsoft Azure.
