    Generic top-level domainsIDNDNSSEC

    Overview

    .SINA is a brand generic top-level domain (gTLD) applied for and operated by Sina Corporation. It was created to provide Sina with a top-level namespace for brand protection, recognition, and hosting of Sina-related services and properties. The TLD is categorized as a brand gTLD and is intended primarily for use by Sina and related entities.

    History

    • Applied for as part of ICANN's New gTLD Program (application revealed 13 June 2012).
    • Delegated to the DNS Root Zone on 30 March 2016.
    • Registry/operator information in source material lists Sina Corporation as the registry operator; the registry infrastructure/provider is listed as Afilias and the TLD status is Delegated.

    Usage and Audience

    • Primary audience: Sina Corporation and its affiliated entities (subsidiaries, business units, channels and services).
    • Target communities: users of Sina's online media, mobile value-added services (MVAS), and global Chinese communities reached by Sina properties.
    • Relevant Sina properties mentioned include SINA.com, Weibo.com, and SINA Mobile, reflecting the company's focus on online news, microblogging, MVAS, media streaming, and other internet services.

    Registration Rules

    • Initial restriction: Registrations under .sina are initially restricted so that only Sina itself can register (defensive, exclusive use by the brand).
    • Planned exclusivity period: Sina planned to maintain exclusive registration for approximately three years after launch, with the approach to be regularly evaluated.
    • Potential phased rollout: After the initial exclusivity period, Sina may consider a phased commercial rollout depending on market demand and other factors.
    • Eligible registrants (as described by the applicant) may include:
      • subsidiaries or branch companies
      • official or frequently used names of departments or business units
      • channels, services, products, events, or campaigns
      • members of the board, staff, affiliated persons, partners or collaborators
      • other entities, sub-groups, or personnel as further defined by Sina
    • Registrant capabilities: Eligible registrants are expected to be able to register one or multiple second-level .sina domain names and act as users or administrators; specific roles and responsibilities are to be defined prior to launch.

    SEO and Brand Impact

    • Purpose: The .sina gTLD was positioned primarily as a tool for trademark protection, brand recognition, and to preserve user experience at the top-level of the DNS for Sina-owned properties.
    • Brand positioning: The registry's approach is defensive and conservative, intended to minimize operational and marketing risks while maintaining control of the Sina namespace.
    • Trust and governance: Sina emphasized providing registry services in a "safe and trusted environment" and planned to issue clear registration policies and guidance to its registrants.
