cqueues is a comprehensive event and networking library for Lua 5.2 and LuaJIT using modern Unix O(1) polling facilities. It includes libraries for buffered socket I/O, SSL/TLS sockets, DNS querying, signal handling, threading, file change notification, and X.509 key management. It natively supports Linux, *BSD, OS X, and Solaris systems without third-party dependencies, and is interoperable with any event loop that accepts plain descriptors, or is usable standalone.
ext-Dns is a core library, an extensible forward DNS server, and some additional tools designed to create DNS server solutions which are able to do any additional operation at the resolution level (running commands, rewritting replies, gathering stats, and so on), without any limit. It provides a ready-to-use solution in case you want to build a DNS server which takes additional actions at the resolution level in an easy way. That is, its design is focused on allowing people to implement whatever they like when a request is received, freeing them from most of the details which involves handling DNS protocol.
Unnamed un-names unwanted DNS entries. It was written to solve the problem of upstream DNS servers inserting bogus records for NXDOMAINs. It can be used to filter unwanted domain names like ads, porn, time wasters, etc. It is modular, so extensions are easy. Extensions can be written in Lua or compiled as shared objects.
DNSCrypt OSX Client is a user interface to conveniently start/stop dnscrypt-proxy and change DNS settings. It was specifically designed to use DNSCrypt with the OpenDNS public DNS resolvers. It includes a preference pane, a menu bar indicator, and a set of scripts for interacting with the system.
Collax Business Server is an all-in-one Linux server for small- and medium-sized businesses. It delivers all the important network services within a heterogeneous business environment for communication, infrastructure, compliance, groupware, and storage, all in a reliable and secure way which is easy to manage. It also provides essential security functions such as firewalling and virus and spam filtering, to protect against hacker attacks, viruses, and unsolicited email messages.
OpenNIC Wizard simplifies the process of switching over to using the OpenNIC DNS (Domain Name System) resolver pool in order to gain access to OpenNIC domains (.geek, .oss, .free, etc.) as well as continuing to be able to resolve legacy ICANN domains (.com, .org, .net, etc.). Using OpenNIC Wizard means you can switch over to OpenNIC without knowing anything about DNS or about configuring custom DNS settings.
The Dynamic Router Lite II project is a router project by the Dutch national police agency that allows Web-based client-control over the next-hop router for the client. A Dynamic Router Lite II system is placed as a default gateway between one or more client networks and a router network with multiple gateway-routers on it. The Dynamic Router Lite II system does policy-based routing with policy-based DNS to match the routing policy. By default a client will have no active gateway, and any attempted HTTP traffic to any domain will lead the user to the router's Web interface, where the user can then pick an appropriate next-hop router. Once picked, all traffic for the client including DNS will be forwarded to the next-hop router the user picked.
