Use the Dns control to integrate domain name resolution into any COM application, allowing your application to easily resolve domain names, host addresses, and email addresses. Features include:
- The Dns control bypasses Winsock system services, so you can query ANY Domain Name Server on the Internet.
- Resolve a domain name to a dot address (forward lookup)
- Resolve a dot address to a domain name (reverse lookup)
- Resolve an email address to the mail server responsible for the mail server (mx lookup)
- The Dns control comes complete with extensive samples.

' Specify the DNS server to use to resolve the request
Dns1.ServerName = "Dns1.nameserver.com"
' Get the IP address for a url
' show the result to the user
MsgBox "Address of dart.com: " & Dns1.Addresses(1)
