JAS Global Advisors/simMachines Study
Please find attached version 1.0 of the joint JAS/simMachines study regarding namespace expansion. In this study, we analyze nonexistent domain (NXD) responses issued from the Root Nameservers in response to queries for names within proposed new Generic Top Level Domains (gTLDs). We focus our analysis on the Second Level Domain (SLD) strings in these queries and, where available, the IP addresses making the queries to the Root. The Study provides statistics concerning the entire population of queries resulting in NXD responses, as well as details for each of the proposed new gTLDs. The data is based on the "Day In The Life" (DITL) data collected by the DNS-OARC.
