OpenDNSSEC is software that manages the security of domain names on the Internet. The project intends to drive adoption of Domain Name System Security Extensions (DNSSEC) to further enhance Internet security.

Domain Technologie Control (DTC) is a Web-based control panel for hosting that can delegate the task of creating subdomains, email, and FTP accounts to users for the domain names they own. It has support for many programs, including bind 8 and 9, MySQL, Apache, PHP 4, qmail, Postfix, Courier, Dovecot, ProFTPD, Webalizer, and mod-log-sql. It can also generate backup scripts, calculation scripts, and config files using a single system UID/GID, and monitor all traffic accounting per user and per service. It is fully skinnable and translated into several languages.

Knot DNS is a high performance authoritative-only DNS server. It supports all key features of the domain name system including zone transfers, dynamic updates, and DNSSEC.

With a small codebase, the PowerDNS Recursor is an advanced resolver currently serving the DNS resolving needs of over 80 million Internet connections. Besides high performance (using kqueue or epoll, over 100 thousand qps on commodity hardware), it provides advanced anti-spoofing measures. In addition, the program caches server performance and timeouts, making it both network and user friendly. It also has built-in hooks for making graphs with rrdtool, providing insight into nameserver performance.

gPXE is a network bootloader. It provides a direct
replacement for proprietary PXE ROMs, with many
extra features such as DNS, HTTP, iSCSI, and more.

Dual DHCP DNS Server is a DHCP server combined
with a caching DNS server that is sensitive to the
names that were allocated by the DHCP server. It
has built in dynamic updates, and also supports
BOOTP PXE network booting and client specific
options. It is self-configuring, doesn't require
the creation of zone files, and uses little memory
and CPU time. Either one of the two services can
be turned off.

pdnsd is a Proxy DNS server for Linux and FreeBSD that is designed to cope with unreacheable nameservers (e.g. because the dial-in link is not up) in a graceful manner to prevent DNS-dependent applications like Netscape from hanging. It has a permanent disk cache (i.e. the cache contents are saved in a file on exit) and supports parallel query and a wide variety of link uptests. It also has the ability to serve some types of locally defined records.

Admin4 is a tool for server maintenance via several plugin modules, running on Windows, Mac OS X, Linux, and many more platforms. Currently, plugins for BIND DNS, LDAP, and PostgreSQL are included. It is designed as a framework, using Python for fast development of plugins and custom modifications. The DNS plugin should be able to query (axfr) any type of server, and performs updates via DDNS, which ensures that it won't interfere with other DDNS clients (DHCP, SAMBA4). For BIND 9.7 and up, statistics are supported as well and used to retrieve the server's zones automatically. The LDAP plugin features browsing and generic editing of all types of LDAP entries with schema support. In addition, high-level editing of objects like users, groups and samba domains is supported. Custom objectClasses and attributes can easily be added. The PostgreSQL module features a query tool with centrally stored snippets, a data tool with filter presets and a database object browser.

dnstracer determines where a given Domain Name
Server (DNS) gets its information from, and follows
the chain of DNS servers back to the servers which
know the data.

MyDNS is a free DNS server for Unix. It was implemented from scratch and is designed to serve records on-the-fly, directly from a MySQL or PostgreSQL database.

Addns.pl is a self-contained DynDNS update client for DynDNS.org (and possibly others). It supports a variety of IP detection methods including external webcheck/router pages. It also supports multiple configurations and hostnames, smart abuse prevention, and custom/static/dynamic DNS, and can run as a daemon, commandline options only, or with a configuration file.
