• TCP control can be used to implement standard upper-layer protocols (such as WHOIS and Time), as well as any custom protocols you want to develop.
• UDP control can likewise be used to implement standard upper-layer protocols (such as Network Time Protocol), as well as custom protocols that use datagram-level communications.
• Daemon control accepts incoming connections, then TCP controls can be created on new threads, implementing custom multi-threaded server applications.
• DNS control is implemented directly (does not use Winsock services), so you can do address look-ups, reverse address look-ups, and mail address look-ups (from MX records).
• RAS control provides complete control over dial-up IP services.
• Ping control checks if a host is reachable.
• Supports COM+ Component Services.
• Can be used in a multi-threaded environment.
• Includes a royalty-free license.
• Wrapper classes included for convenient integration into Visual C++.
• 100% .NET compatible using .NET COM interop, samples included.
