The DNS involves resolving client’s queries with multiple hosts across different regions. Multiple servers help many organizations by increasing response rate and network efficiency for clients. But, some organizations have special demands that require a specific server to resolve queries for a particular domain name. DDI Central can solve this problem with its domain view feature.
Restricting domain name resolution to certain hosts based on their subnets
Let’s look at a scenario where a domain name—zylkerstores.com—is linked to three different DNS servers. The organization wants the queries from three subnets—subnet one (172.169.158.0/24), subnet two (172.169.159.0/24), and subnet three (172.168.160.0/24)—each from a different department and to be resolved by server1, server2, and server3, respectively.
DDI Central can help in this scenario in both Linux-based ISC-Bind9 DNS/DHCP servers and Microsoft Windows DNS/DHCP severs.
How DDI Central helps in Linux
DDI Central can help you configure a customized DNS response for specific domain names to certain departments in Linux with the domain view feature.
This feature allows you to direct the queries of clients within an IP address range to a specific host for DNS resolution.
Here’s a step-by-step guide on how to configure DNS domain views:
1. Log in to DDI Central. From the dashboard, hover over the left pane and click DNS.
2. Click Views on the left. On the page that appears, click the Add View button in the upper-right.
3.Provide a name for the view, i.e., view1, for the domain name (zylkerstores.com).Provide each view with a match client input as a specific client subnet network address.
4.Click Save.
Repeat step two for two additional views, i.e., view2 and view3.
Associate them with the selected domain name (zylkerstores.com) for resolution.
How DDI Central helps in Microsoft Windows
DDI Central provides zone scopes in Windows for seamlessly customizing DNS responses for different segments. This feature allows network administrators to modify the responses at a minor level for each record in the scope.
Here’s a step-by-step guide on how to configure DNS zone scopes:
1. Create or update the domain and add more than one zone scope based on the number of departments.
2. Add DNS records with IP address values in each scope and apply configurations.
3. Create new named client subnets by specifying the subnet network address.
4. Create a DNS query resolution policy and associate the client subnet with it.
