Open Source C 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.

SmartDNS is a local DNS server. SmartDNS accepts DNS query requests from local clients, obtains DNS query results from multiple upstream DNS servers, and returns the results with the fastest access speed to clients, improving network access speed. At the same time, it supports the designation of specific domain name IP addresses, and high-quality matching to achieve the effect of filtering advertisements. Different from all-servers of dnsmasq, smartdns returns the resolution results with the fastest access speed. Supports Raspberry Pi, openwrt, ASUS router, windows and other devices. Supports domain name suffix matching mode, simplify filtering configuration, filter 200,000 records in less than 1ms. Supports domain name shunting, different types of domain names are queried to different DNS servers. Support standard Linux system (Raspberry Pi), various firmware of openwrt system, and native firmware of ASUS router. And support for Windows 10 WSL (Windows Subsystem for Linux).

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.

MyDNS-NG is the Next Generation DNS Server for fast and scalable sql based DNS services.

It is a versatile DNS Proxy server with DNS firewall which filters DNS traffic between local computer and DNS servers with flexible rules, supports blocking by IP geography, caching, import/export rules into XML. With a click of a button acts as a DNS proxy (or DNS server), supports multiple client authentication methods, calculates statistics for DNS servers and proxy clients, supports load balancing between multiple upstream DNS servers.

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.

InjectSOCKS is an open source utility for Microsoft Windows. It forces foreign software to create any TCP connection through a SOCKS V5 tunnel like Tor. It also covers DNS requests of the foreign software in a way that they aren't leaked. The implemented technology is independent from the used protocols on TCP, so it works for HTTP, HTTPS, passive FTP, SMTP, etc.

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.

Heyoka is an advanced tool to perform DNS tunneling in a flexible and reliable way. It uses binary encoding in order to speed up the data transfer, and spoofs the DNS requests in order to be harder to detect. Currently in alpha state.

The Dynamic DNS project aims to provide a free and open dynamic dns server and a suite of multi-language api tools for integrating dynamic dns services into applications.

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

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.

This is an enhanced version of the original pgsqldb interface which is included with the BIND-9.x

Objective: To add capabilities to Bind 9 that will allow Bind backend databases to support adding and removing zones without interrupting normal server operation.

Software for reliable url cloaking system using low q.o.s hosts and lines such as home PC's and dsl or cable connections. CDUCK combined DNS-server and webserver functionality and strict security for the creation of reliable domain web cloaking.

CartoReso intends to facilitate enterprise computer network mapping.
