Simple DNS Plus

Oi
Simple DNS Plus is a DNS server software product that runs on x86 and x64 editions of Windows operating system.

All options and settings are available directly from a Windows user interface. It provides wizards for common tasks such as setting up new zones, importing data, making bulk updates, etc.

It has full support for IPv6. 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.

It has full support for internationalized domain names (IDNs). 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.

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 a full .NET/COM programming API.

Simple DNS Plus is based on the Microsoft .NET Framework 4.8 and is 100% managed code, protecting it from common security issues such as buffer overruns, and making it run natively on both 32 bit and 64 bit CPUs and Windows versions, including Windows Vista.
