What about System.Net.Dns?
The DNS classes built into Microsoft .NET platform fall woefully short of complete DNS support. The System.Net.Dns class can only perform forward and reverse DNS lookups. If you need to resolve a host name into an IPAddress or find a host name for a given IPAddress, then the system DNS classes will do everything you need. The shortfalls of the system classes become apparent when you need to contact a different DNS server, you need other DNS record types, or you want to do real-time queries and not depend on host files or cached entries.
