Recommendation DescriptionCurrent Phase

Recommendation 1

Dotless domains will not be universally reachable and the SSAC recommends strongly against their use.  As a result, the SSAC also recommends that the use of DNS resource records such as A, AAAA, and MX in the apex of a Top-Level Domain (TLD) be contractually prohibited where appropriate and strongly discouraged in all cases.
