What is MaraDNS ?

MaraDNS is a free open-source computer program written by Sam Trenholme.

MaraDNS implements the Domain Name System (DNS), an essential internet service. MaraDNS is open source software: This means that anyone is free to download, use, and modify the program free of charge, as per its license.

People like MaraDNS because it’s small, lightweight, easy to set up, and remarkably secure. It’s also cross platform — the program runs both in Windows and in UNIX clones.

More information describing MaraDNS is on the overview and summary page.
