How to Use DNS Audit to Investigate and Troubleshoot DNS

Here we can see, “How to Use DNS Audit to Investigate and Troubleshoot DNS”

Every device connected to the Internet has an IP address, as we all know, and this IP address essentially serves as the device’s identity. So, whenever another device, such as your computer, wants to interact with or access a certain device, all you need is the IP address and any credentials if it’s a remote device.

As a result, we’ll show you how to do a DNS audit and troubleshoot any DNS issues in your IP range in this article.

The DNS Audit Tool is available for download.

We’ll be using a product from Solarwinds, a well-known and well-respected business in the field of system and network administration. Solarwinds Engineers Toolset (download here) is a bundle of networking tools that you can easily use to do your daily networking activities.

After you’ve downloaded the software, follow the on-screen instructions to install it on your computer.

What is the DNS Audit Tool, and how does it work?

The DNS Audit application scans a range of IP addresses and performs reverse DNS lookups for each address to help you find DNS database issues. When DNS Audit receives a DNS answer for an address, it does a forward DNS query to ensure that the forward lookup resolves to the IP address that was originally scanned.

DNS Errors in an IP Range Troubleshooting

  1. First and foremost, you must access the Engineer’s Toolset. To do so, go to the Start Menu and search for it, or if you just installed it, go to Recently Added and click on the Toolset Launchpad option.
  2. After you’ve accessed the Toolset Launchpad, navigate to IPAM/DNS/DHCP on the left-hand side, and then hit the DNS Audit Launch button.
  3. Following the tool’s startup, you’ll need to enter the starting and finishing IP addresses. So, go ahead and enter the IP address range you’d like to scan, then hit the Scan button.
  4. The utility will begin scanning the IP address range and display the results in a table.
  5. By using the Filter drop-down option, you can narrow down the results displayed. Select the Forward DNS Errors option if you only want to view DNS errors.
  6. After you’ve finished, you can export the table data in one of the many formats available. To do so, choose the File drop-down menu and then Export with your pointer.
  7. You may also print the table by selecting File > Print from the menu bar.
