The domain name system (DNS) is one of the core services in today's network
structures. In local and ad-hoc networks DNS is often enhanced or replaced by
mDNS. As of yet, no simulation models for DNS and mDNS have been developed for
INET/OMNeT++. We introduce DNS and mDNS simulation models for OMNeT++, which
allow researchers to easily prototype and evaluate extensions for these
protocols. In addition, we present models for our own experimental extensions,
namely Stateless DNS and Privacy-Enhanced mDNS, that are based on the
aforementioned models. Using our models we were able to further improve the
efficiency of our protocol extensions.Comment: Published in: A. F\"orster, C. Minkenberg, G. R. Herrera, M. Kirsche
