The software implements a DNS Server for all Windows platforms.

The server can run as Primary or Backup name server and supports dynamic DNS updates based on RFC 2136.
The server operates as a so called "recursive DNS forwarder" with caching. Requests for non local domains are answered from the cache or forwarded to external nameservers.

in Version 2.0:
DNS over TLS as specified in RFC 7858

The installer contains the 32bit software and native x64 versions of the server programs.

The DNS Server is implemented for Windows XP/VISTA/20xx/7/8/10/11 as native service for background operation. A Control Panel applet provides interactive access to the service.

The DNS Server is also provided as portable application.

The software is shareware.
