Here are a few items to note about aspNetDns to help you get more familiar with its functionality.

What is aspNetDns?

 
aspNetDns is a .NET DNS component, also known as an assembly. It is written in 100% C# for speed and efficiency. It does not have any dependencies on any unmanaged code. aspNetDns only requires the .NET framework to be installed on the computer.
 

Can I use aspNetDns in windows applications?

Absolutely! You can use aspNetDns from a Windows Form application, XML Web Services, ASP.NET web pages, and any other .NET supported application.

What can aspNetDns do for me?

aspNetDns allows you to programmatically perform DNS record lookups.  aspNetDns can be used from ASP.NET web pages, to windows forms, to web services. The only limitation to using aspNetDns is your programming imagination.

What’s the difference between aspNetDns and System.Net.Dns found in the .NET Framework?

The System.Net.Dns namespace only returns IPHostEntry values. Basically this means that it can only perform Address record lookup and Reverse Lookups. However, because windows can employ netbios and wins, sometimes these methods actually return Netbios and Wins database information, instead of the actual information found in the DNS Servers, resulting in fault results.

 

aspNetDns can perform over 20 different queries. It can perform all of these synchronously or asynchronously. It also has the capability of using different DNS servers for Fail over capabilities. aspNetDns also has the capability to specify timeouts and return all records that belong to a DNS class.  For a tabular comparison, view the table below.

 

Here is a list of aspNetDns in table format.
