Section I: Description, Explanation, and Purpose

Consistent with the Name Collision Occurrence Management Framework [PDF, 926 KB] approved on 30 July 2014, the Board New gTLD Program Committee directed staff to provide each registry operator a Name Collision Occurrence Assessment ("Name Collision Assessment"), issued on 4 August 2014. Per the Name Collision Occurrence Assessment, for names included on the SLD Block List of the registry's Alternate Path to Delegation Report and recorded in the Trademark Clearinghouse that the registry withheld from allocation during its Sunrise Period or Claims Period, the registry must continue to withhold these names from allocation while ICANN consults with the community. This paper [PDF, 114 KB] examines operational and other considerations for several approaches regarding the appropriate Rights Protection Mechanisms for release of SLD Block List names.

Section II: Background

The Name Collision Assessment requires certain measures to be implemented for each top-level domain. In particular, it provides that for gTLDs delegated prior to 18 August 2014 who have activated names, the registry must ensure that second-level domain names desired to be activated from its SLD Block List after the 90-day controlled interruption period have been subject to applicable Rights Protection Mechanisms as required under Specification 7 of theRegistry Agreement.

Based on feedback and discussion to date in the community regarding appropriate Rights Protection Mechanisms for names in the SLD Block list, several possible approaches are described in this paper for the handling of these names. ICANN is requesting community feedback on these alternatives, or proposals for additional measures.

Currently, names released from the SLD Block List after a TLD's Sunrise period has occurred are subject to the Trademark Claims service on release. Various stakeholder groups have provided feedback suggesting alternatives, for example, a required Sunrise period, or a similar period incorporating some elements of the Sunrise process.

  1. <The following description is a gross simplification, but hopefully will suffice for the purposes of this comment.>

    Enterprises often deploy private name spaces which can be resolved only within their corporate network. Prior to the release of new gTLDs, if those addresses were used on the open Internet (such as when traveling), they would not resolve in the public DNS. With the deployment of many new gTLD, it is possible that a private address, when used outside the enterprise, could now resolve, sending the user (or e-mail) to the wrong place. This is called a "name collision". There are other scenarios which can also cause name collisions.

    To address the problem, some TLDs which are commonly used as the TLD in private namespaces (.CORP, .HOME, .MAIL) will not be delegated for the foreseeable future. For other less common TLDs, the TLD may be delegated, but 2nd level names that are commonly used in private namespaces will be reserved. These reserved names will be monitored, and if usage does not actually occur, the 2nd level name could be released at some later date.

    The problem is that when names are made available when a TLD starts operation, certain trademark and other rights protection mechanisms are used (Trademark Clearinghouse, Sunrise periods). Names released later might not be subject to these same protections.

    The purpose of this Public Comment is to solicit input on how 2nd level names released after TLD startup should be protected.

    I see no reason that the ALAC needs to submit a comment.
