The precise technical language often found in RFCs, while often providing consistency and clarity to technical communities, can sometimes be incomprehensible or misleading when used in a non-technical setting.

The purpose of this document is to increase the understanding of terms used commonly when discussing the root server system to the broader ICANN community. It is not to redefine or provide guidance to any technical communities on the correct use of these terms. This document and its terms should be useful to anyone discussing the DNS root server system. This includes RSSAC members, RSSAC Caucus members, ICANN staff, and the larger ICANN community. It will be updated by the RSSAC as the vocabulary used to discuss the root server system evolves.
