How to Use DNS Audit to Investigate and Troubleshoot DNS
The article “How to Use DNS Audit to Investigate and Troubleshoot DNS” is shown for our perusal here.
We are all aware that each and every device that is linked to the Internet possesses an IP address, and that this IP address, in essence, serves as the device’s identification. Therefore, whenever another device, such as your computer, wishes to interact with or access a particular device, all you need is the IP address of the device in question, as well as any credentials necessary if the device in question is remote.
In this post, as a result, we will demonstrate how to do a DNS audit and how to troubleshoot any DNS issues that may occur inside your IP range.
The DNS Audit Tool is available for download.
The DNS Audit Tool can be downloaded at your convenience.
Solarwinds is a well-known and highly-respected company in the field of system and network administration, and we will be utilising a product developed by this company. The Solarwinds Engineers Toolset is a collection of networking tools that may be readily utilised by you to carry out your day-to-day networking tasks. You can get it here.
After you have downloaded the programme, you will need to follow the directions that appear on the screen in order to install it on your computer.
What is the DNS Audit Tool, and how does it work?
In order to assist you in locating problems with the DNS database, the DNS Audit application will examine a range of IP addresses and conduct reverse DNS lookups for each address. When DNS Audit obtains a DNS answer for an address, it next conducts a forward DNS query. This is done to verify that the forward lookup successfully resolves to the IP address that was initially scanned.

DNS Errors in an IP Range Troubleshooting
You should begin by gaining access to the Engineer’s Toolset as your first order of business. To accomplish this, open the Start Menu and conduct a search for it; alternatively, if you have only recently installed it, open the menu item labelled Recently Added and select the option labelled Toolset Launchpad.
After you have gained access to the Toolset Launchpad, proceed to the IPAM/DNS/DHCP section on the left side of the screen, and then click the DNS Audit Launch button.
After the tool has been started up, you will be prompted to enter the beginning IP address and the ending IP address. Therefore, go ahead and enter the range of IP addresses that you want to scan, and then click the Scan button when you are finished.
The IP address range will be scanned after the application is activated, and the results will be displayed in a table.
You can make the results presented more relevant to your search by using the Filter drop-down option. If you simply want to view DNS issues, select the Forward DNS Errors option from the drop-down menu.
When you are finished, you have the option of exporting the data from the table into any one of the numerous formats that are accessible. To accomplish this, go to the drop-down menu labelled File and select Export with your pointer.
You also have the option to print the table by going to the File menu and selecting Print from there.
