There was discussion today on the newly forming work party about rogue behavior (a work party name change may occur, but I'm using the current one) about whether existing RSOs were serving data other than the root, arpa and
root-servers.net from their existing root server infrastructure. One of the questions was whether TLDs were being served authoritatively from some instances. I threw together a few quick bash scripts to do minimal checking of this and determined that based on advertised addresses and the root zone data, there are no RSOs currently advertising TLD service within the root zone data.
