I propose a poster to accompany my proposed talk (of the same title). The poster will summarise my efforts to update the DNS components of Twisted and discuss some of the things I've learned along the way. I'll demonstrate the EDNS0, DNSSEC and DANE client support which I have been working on and show how these new Twisted Names components can be glued together to build novel DNS servers and clients.
Twisted is an event-driven networking engine written in Python and licensed under the open source MIT license. It is a platform for developing internet applications.
