Simple yet Powerful. 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.
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.
USER interface can be run on a desktop computer connecting to a remote Simple DNS Plus server, making it easy and fast to manage the server without Remote Desktop, VNC, or similar. You can even remote manage a Simple DNS Plus service running on Windows Server Core (no GUI on server)
Direct support for dynamic IP clients
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.
Full support for IDNs (internationalized domain names)
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.
Cache snapshot viewer
Browse the current DNS cache with this intuitive explorer style tool.
Detailed log files
Optionally writes all DNS queries and answers to a log file which you can then analyze at your convenience.
Remote logging to Syslog server
Log data can be sent to a remote syslog server using the standard syslog protocol (RFC3164). This can be useful centralize logging and/or take advantage of various alerting features of syslog server software.
Raw log files for incoming request data
This can be used analyze DNS request traffic for security review or for example to compile usage statistics for domain names, customers, etc.
Protects against DNS spoofing (a.k.a. "cache poisoning")
Restrict recursion by client IP address
You can specify exactly which clients (by IP address/subnet) that you want the server to perform recursion for
Response Filtering stops "DNS rebinding attacks"
"Stealth DNS" option
DNS Plus has a special "stealth" option which makes it invisible to hackers using DNS port scanners, by not responding to a DNS request unless it is for data in local zones or originates from a client offered recursion.
Secure Zone Transfers
Avoid revealing all your server addresses and other potentially sensitive data by limiting who can zone transfer your zones.
IP address blocking
Ignore packets from known offenders, and automatically add anyone making too many requests to quickly (DoS attack) to the list.
