Independent Submission J. Levine Request for Comments: 7085 Taughannock Networks Category: Informational P. Hoffman ISSN: 2070-1721 Cybersecurity Association December 2013 Top-Level Domains That Are Already Dotless Abstract Recent statements from the Internet Architecture Board (IAB) and the Internet Corporation of Assigned Names and Numbers (ICANN) Security and Stability Advisory Committee have focused on the problems that the DNS is likely to experience with top-level domains (TLDs) that contain address records (so-called "dotless domains"). In order to help researchers determine the extent of the issues with dotless domains, this document lists the current dotless TLDs and gives a script for finding them. This document lists data about dotless TLDs but does not address the policy and technology issues other than to point to the statements of others.

Introduction In the past few years, well-respected groups have issued documents about top-level domains in the DNS that contain address records (so-called "dotless domains"). The Security and Stability Advisory Committee (SSAC) of the Internet Corporation for Assigned Names and Numbers (ICANN) issued a report called "Report on Dotless Domains" [SAC053] in February 2012. The Internet Architecture Board (IAB) issued a statement called "Dotless Domains Considered Harmful" [IAB-DOTLESS] in July 2013. The New gTLD Program Committee of the ICANN Board of Directors (NGPC) approved a resolution on dotless domains [NGPC-DOTLESS] in August 2013. (The authors of this document note that they are not on the SSAC, the IAB, or the ICANN Board.) All of these documents consider the effects of dotless domains without describing the extent of their current deployment. In order to help researchers determine the extent of the problems with dotless domains, this document lists the known dotless domains at the time of publication and shows how researchers can find them in the future. In this document, we consider any TLD with an A, AAAA, and/or MX record at the apex to be dotless. This document is meant to provide current data to the Internet community but does not give advice. Levine & Hoffman Informational [Page 2] RFC 7085 Already Dotless TLDs December 2013 Many people have expressed a belief that ICANN prohibits all TLDs from being dotless. That belief is not true; ICANN's policies apply only to their contracted TLDs. This document shows the extent to which dotless domains exist today. 2.
