Open Source BSD DNS Software

This is a command line utility to resolve DNS requests via a SOCKS tunnel like Tor or a HTTP proxy.

A client for automaticly updating your EZ-IP.net, justlinux.com, dhs.org, dyndns.org, ods.org, gnudip.cheapnet.net, tzo.com, easydns.com dynamic hostname parameters. Includes daemon support that only sends updates if your IP address changes.

Blocky is a fast, lightweight DNS proxy and network-wide ad blocker designed for home labs and small networks that want Pi-hole-like filtering with more flexible DNS routing and modern protocol support. It blocks DNS queries using external deny lists while also supporting allow lists, and it can scope policies by client groups so different devices or households can have different rulesets. Unlike a single-purpose blocker, it supports advanced DNS behavior such as conditional forwarding and custom resolution for specific domains, letting you shape traffic in ways that fit split-horizon DNS, internal services, or privacy-focused upstream strategies. Performance is a major focus, with configurable caching, prefetching, and the ability to use multiple upstream resolvers simultaneously to reduce latency and avoid single points of failure.

Self Integrated DNS DHCP Server Open Source Freeware Windows/Linux. Works as DHCP or DNS Server or both. Using both services automatically adds DHCP allotted hosts automatically to DNS Server. Support Relay Agent, PXEBOOT, BOOTP, Zone Trasfer, DHCP Range Filters. Download.

A DNS server for Unix and Windows platforms, supporting authoritative service (master/slave) as well as caching. Also featuring a graphical master file editor (mfedit), a graphical DNS query tool (dnsquery) and a DNS programming library for C++ (poslib).

Poweradmin is a web-based DNS administration tool for PowerDNS server. The interface has full support for most of the features of PowerDNS. It has full support for all zone types, for supermasters, full support for IPv6 and multi-language support.

MaraDNS is a fully open-sourced DNS server that strives to be secure. It is written in C (no C++) and is suitable for embedded systems.

Ddclient is a Perl client used to update dynamic DNS entries for accounts on 'Dynamic DNS Network Services' free DNS service. It currently supports a lot of different routers and a few different services. The project moved to github. See https://www.github.com/ddclient/ddclient for support.

dnswalk is a DNS debugger. It performs zone transfers of specified domains, and checks the database in numerous ways for internal consistency, as well as accuracy.

ISPMan is a system to design massive ISPs using LDAP as the backend. ISPMan provides a web front end and a command line interface to create virtual domains and manages users, dns information, email infos and httpd setup data for these vhosts.

Moved to GitHub → https://github.com/yoctobyte/visualsynapse --- Visual Synapse are component wrappers around the Synapse tcp/ip libraries. It wraps a few common internet protocols, like HTTP, UDP, DNS, ICMP, TCP and SMTP to multi-threaded components that can be used with Delphi, Kylix, Freepascal and C++ Builder.

Passive network application response time monitor utilising libpcap packet capture. Maintains session state tracking host response, network round-trip times and end-point/network congestion. Can be configured for many protocols such as http, telnet...

Zeroconf networking allows easy connection of hosts without needing to setup DHCP servers or assign static IPs. This project is intended to provide support for Zeroconf (http://www.zeroconf.org) networking for Linux and Unix machines.

This project is to enhance the python DNS library initially written by Guido van Rossum, then extended by Anthony Baxter, Michael Ströder and others.

Dynamic DNS update tool for DynDns services. Features: Stateful memory, a complete activity log, configuration file, and cross-platform portability.

NSTX - An IP-over-DNS implementation. Creates a bi-directional IP-tunnel through (valid) DNS-requests.

An implementation of the DNS protocol in Java. dnsjava includes a set of classes that can be used within other programs and several user tools.

The dnsutl package is a collection tools to make administering DNS easier. These include reverse map generation, validation, and much more. All of these programs are robust when faced with all the peculiar semantics of DNS resource files.

The internet storage name service (iSNS) is used to register iSCSI and iFCP storage devices in the network. The iSNS allows dynamic discovery of available storage targets by storage initiators. The iSNS specification is located at http://www.ietf.org/
