The simple yet powerful DNS server for Windows.
Thanks to DNS servers we surf the Internet using names such as "www.simpledns.com" instead of impossible to remember IP addresses.
DNS servers translate these domain names into machine readable IP-addresses needed to locate the requested web-server on the Internet.
With Simple DNS Plus you can hosts your own domain name, or simply speed up Internet access by running your own DNS server.
Simple DNS Plus can easily be integrated with your web-site for ISP customer signup etc., or even a full web-based DNS solution.
Simple DNS Plus is also a DHCP server, it comes with a DNS Look Up tool, and many other features

Features
Simple yet Powerful
What makes Simple DNS Plus "simple" is its easy-to-use user interface and automation features.
All options and settings are available directly from the intuitive Windows user interface.
It provides wizards for common tasks such as setting up new zones, importing data, making bulk updates, etc.
You never need to mess with cryptic configuration files or registry settings.
Novice users can have their DNS server up and running correctly and securely in no time.
But make no mistake - Simple DNS Plus is a very capable and full featured DNS server, and it has plenty of options for expert users to tweak it just the way they want.
Authoritative and Recursive (resolver and cache) DNS server
All the DNS server features and functionality you need to host DNS for domain names, assign domain name to computers and devices for easy access, create and delegate sub-domains, resolve other domain names on the Internet, speed up Internet access with centralized DNS caching, etc.
High performance DNS server engine and user interface
Great for hosting and managing anywhere from a few domains to +100,000 domains.
The user interface is optimized to handle really large domain name portfolios.
Highly configurable
Simple DNS Plus has options to configure all aspects of the DNS services, including many unique but important options not found in competing products such as the ability to limit recursion by IP address. Options are well organized and easy to manage in a central Options dialog available directly from first toolbar button in the main program window.
Of course the software comes preconfigured with settings that are appropriate for most users.
Direct support for dynamic IP clients
Simple DNS Plus supports TSIG authenticated dynamic DNS updates.
This update method is more efficient than the HTTP based and other proprietary update methods typically used because it happens directly via the DNS protocol.
Several dynamic IP updater applications can be used with this.
Setup tutorials are provided for DynSite and DirectUpdate.
Simple DNS Plus can also function as a dynamic DNS service for more generic HTTP based update clients by using a web-server front-end. ASP.NET and classic ASP sample code for this is available here.
Full support for IDNs (internationalized domain names)
In Simple DNS Plus you can enter domain names with native characters directly (no punycode conversion needed), and have an option to display native character or punycoded domain names anywhere in the user interface, and quickly switch between these modes.
Full support for IPv6
Simple DNS Plus v. 5.0 has full support for IPv6 - the next Internet Protocol version.
It has an option to control protocol preference (IPv4 / IPv6) on dual-stack computers, and it can even act as IPv6-to-IPv4 or IPv4-to-IPv6 forwarder.
Easy to integrate with other applications
You can create DNS records or entire zone files from other applications or web-sites and prompt Simple DNS Plus to dynamically load and use this through command line options, a simple HTTP API, and our full .NET/COM programming API.
The included help file contains a complete description of these features.
Simple DNS Plus also allows you to connect with other applications and data from different sources through various plug-ins and can be extended through an open plug-in architecture.
100% .NET 2.0 managed code
This provides great performance - also on 64 bit computers where Simple DNS Plus runs in native 64 bit mode.
And it is very secure because common security issues such as buffer overruns simply cannot happen.
