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:
Certainly it is no surprise to see some of these names (such as local, localhost, and wpad) in the list. We've seen them before when looking at invalid TLDs. And speaking of TLDs, a few valid TLDs appear in this list. Some of those query counts are likely due to DNSSEC (i.e., querying for the zone's keys). The list gets boring pretty quickly, but one interesting pattern keeps appearing. Note that "\032" represents the space character:Rank Count Query ==== =========== ===================== 1 287,650,115 local 2 31,698,784 localhost 3 16,562,544 wpad 4 13,367,843 com 5 12,983,976 ru 6 8,970,691 _nfsv4idmapdomain 7 5,490,837 net 8 4,416,080 \032 9 4,187,822 org 10 3,372,632 mail 11 2,776,746 de 12 2,658,933 uk 13 1,940,390 unifi 14 1,795,716 jp 15 1,725,496 yotaaccessinterface 16 1,679,345 mybooklive 17 1,507,665 pl 18 1,406,996 http 19 1,294,151 arpa 20 1,264,372 helvetica,
