Anonymity is less discussed in the IETF than for instance security
[RFC3552] or privacy [RFC6973]. This can be attributed to the fact
anonymity is a hard technical problem or that anonymizing user data is
not of specific market interest. It remains a fact that 'most
internet users would like to be anonymous online at least
occasionally' [Pew]. This document aims to break down the different
meanings and implications of anonymity on a mediated computer network.
