 Several years ago, I was hosting websites on a server in my garage. Back then, my ADSL modem was very basic, and I wanted to have a DNS server which would resolve to an internal IP address when the domain itself resolved to my public IP. Thus was born [RubyDNS]. This project [was originally built on](https://github.com/ioquatix/rubydns/tree/v0.8.5) top of [EventMachine], but a lack of support for [IPv6 at the time](https://github.com/ioquatix/rubydns/issues/45) and [other problems](https://github.com/ioquatix/rubydns/issues/14), meant that I started looking for other options. Around that time [Celluloid] was picking up steam. I had not encountered actors before and I wanted to learn more about it. So, [I reimplemented RubyDNS on top of Celluloid](https://github.com/ioquatix/rubydns/tree/v0.9.0) and this eventually became the first stable release.
 
-Moving forward, I refactored the internals of RubyDNS into [Celluloid::DNS]. This rewrite helped solidify the design of RubyDNS and to a certain extent it works. However, [unfixed bugs and design problems](https://github.com/celluloid/celluloid/pull/710) in Celluloid meant that RubyDNS 2.0 was delayed by almost 2 years. I wasn't happy releasing things with known bugs and problems. Anyway, a lot of discussion and thinking, I decided to build a small event reactor using [nio4r] and [timers], the core parts of [Celluloid::IO] which made it work so well.

The result is this project.
 
 In addition, there is a [similarly designed C++ library of the same name](https://github.com/kurocha/async). These two libraries share similar design principles, but are different in some areas due to the underlying semantic differences of the languages.
