New Root Operator Representative Appointed to OARC Board

After more than 4 years of service to DNS-OARC, Matt Larson of Verisign recently took the decision to stand down as the Root Operator's representative to the OARC Board. After deliberation, OARC's Root Servers Advisory Committee has decided to appoint John Crain, representing ICANN/L-Root, as his replacement. DNS-OARC would like to congratulate John on his appointment and to thank Matt for his contribution and commitment.

Names Without Dots

ICANN's Security and Stability Advisory Committee recently solicited input (again) on the issue of "Dotless Domains." A fellow OARC member asked me if I could generate a list of the top 50,000 dotless domains seen at the root name servers. This type of data is available in the annual Day in the Life of the Internet (DITL) collections that OARC performs annually. I ran the analys is for the April 2012 data. Out of 30.1 billion queries in the data set, 1.76 billion (5.8%) were queries for single-label names. Here are the top 20:
