Although the information displayed below, received from an authoritative server, it is not itself authoritative in this case. To compare, all the same queries were made on the server where the forward and reverse zones were not configured:.

Here, the machine assigned itself as a default DNS server. The DNS server domain name is displayed as unknown because there are no resource records for the IP address For the same reason, the 2nd query returns an error Non-existent domain.

Application Load Balancing When you have deployed multiple instances of an application at different locations, you can use DNS policy to balance the traffic load between the different application instances, dynamically allocating the traffic load for the application.

Geo-Location Based Traffic Management. You can use DNS Policy to allow primary and secondary DNS servers to respond to DNS client queries based on the geographical location of both the client and the resource to which the client is attempting to connect, providing the client with the IP address of the closest resource. Filtering You can configure DNS policy to create query filters that are based on criteria that you supply. Time of day based redirection You can use DNS policy to distribute application traffic across different geographically distributed instances of an application by using DNS policies that are based on the time of day.

For instance, a bot net can send requests to your DNS server using the IP address of a third computer as the requestor. When you use RRL, you can configure the following settings:. We need to configure how the DNS server will work before adding any actual records. There are three options here. You can either: configure a forward lookup zone only, create forward and reverse lookup zone, or configure root hints only. A forward lookup zone allows you to do the standard DNS function of taking a name and resolving it into an IP address.

A reverse lookup zone allows you to do the opposite, taking an IP address and finding its name. For example, if a user is set up to print to a printer with an IP address of Why you give me so much trouble?

Root hints only will not create a database of name records for lookups, but rather will just have the IP addresses of other DNS servers where records can be found.

If you already have DNS setup on your network, you’ll probably want to continue using the same configuration you already have. If not, use forward and backward for most situations. Backup zones typically don’t hurt anything, and they are nice to have when the need arises. Now, you choose whether this server will maintain the zone, or if this server will have a read-only copy of the DNS records from another server. Next enter your zone name.

If this is your first DNS server, then this needs to be the root zone name for your entire organization. For example, my zone name might be arcticllama. If however, this server will be authoritative only for a subset, and other DNS servers will be responsible for other zones, then the name will need to reflect that.

For example, us. On which port DNS Server runs? Answer the above mentioned question in the comment section given below before you start reading more of this article. It is primarily used for name resolution. As computer understands only numbers and not names but it is difficult for human minds to remember numbers. Therefore DNS comes in the picture, it is used to convert the Domain name i. How many of you have visited Google.

It is highly unlikely administrators will ever need to change the Root Hints servers :. Root Hints. Our next tab, Monitoring is also worth exploring. You can also configure automated test that will run at a configured time interval to ensure the DNS server is operating correctly:.

Next, click on the Event Logging tab. Here you can configure options to log DNS events. By default, all events are logged. Event Logging. When Event Logging is enabled , you can view any type of logged events in the Event Viewer Administrative Tools console.

The Debug Logging tab is next up. Debug Logging allows us to capture to a log file any packets sent and received by the DNS server. Think of it as Wireshark for your DNS server. You can log DNS packets and filter them by direction, protocols , IP addresses , and other parameters as shown below. You can setup the log file location and set the maximum file size in bytes:.

Each Zone or Domain has a specific set of properties which can be configured as shown in figure 15 below. In our example, firewall. Furthermore the zone’s status is shown at the top area of the window — our zone is currently in the running state and can be paused by simply clicking on the pause button on the right:.

Zone Properties. Right below, you can change the zone type to primary , secondary or stub. You can also setup dynamic updates to be secure or not.
