    About .dclk domain

    .dclk is a brand gTLD (generic Top-Level Domain) operated exclusively by Google through its registry entity, Charleston Road Registry Inc. It was delegated to the root zone on 24 January 2015 as part of ICANN's New gTLD Program. The extension was established to provide a dedicated, closed namespace for Google's use, specifically for its DoubleClick advertising services. As a brand TLD, it is not intended for public registration or commercial sale.

    Who can register .dclk domain

    Registration of .dclk domain names is strictly restricted. Only Google and its controlled affiliates can register second-level domains under this extension. The general public, businesses, and other organizations cannot purchase or register .dclk names through any registrar. Charleston Road Registry, the registry operator, also acts as the sole registrar for this TLD, managing all registrations internally for Google's exclusive use.

    How to register .dclk domain

    This TLD is not allocated through commercial registrars. Domain names under .dclk are delegated through an internal process controlled by Google and its registry entity, Charleston Road Registry Inc. All registration decisions are made by Google for its own operational use, primarily related to its DoubleClick advertising platform. There is no public application or purchase process; the namespace is entirely closed and reserved for the registry operator's exclusive purposes.

    Typical uses of .dclk domain

    The .dclk extension is used exclusively by Google for its DoubleClick digital advertising services. Domains under this TLD typically host internal platforms, tools, and services related to ad serving, campaign management, and reporting for the DoubleClick ecosystem. This dedicated namespace allows Google to brand and structure its advertising technology infrastructure distinctly, separating it from its other consumer-facing .google or .youtube brand TLDs. It serves as a secure, branded environment for its enterprise advertising products.

    Tips for registering .dclk domain

    • All domains are registered and maintained indefinitely by Google for its exclusive use; there is no concept of registration terms, renewals, or public pricing.
    • WHOIS privacy, transfer policies, and grace periods are not applicable, as the registry is the sole registrant and registrar.
    • There are no premium domain sales or public auctions, as the entire namespace is privately operated.
    • The registry operates under an exemption from ICANN's Registry Operator Code of Conduct due to its closed, single-registrant model.

    Frequently asked questions about .dclk domain

    Who operates .dclk domain?The registry for .dclk domains is Google Registry, administered by Charleston Road Registry Inc..
    Who can register a .dclk domain?

    Registration is completely closed to the public. Only Google, through its registry entity Charleston Road Registry Inc., can register and use .dclk domain names. This restriction is enforced at the registry level, and no external registrars are authorized to sell these domains. The TLD was specifically applied for and delegated as a closed brand TLD for Google's internal operational use.

    Can I transfer a .dclk domain between registrars?

    Inter-registrar transfers are not possible for .dclk domains. Since Google is both the registry operator and the sole registrant, all domains remain under its control. There is no mechanism for transferring a .dclk domain to a different registrar or to a third party, as the entire TLD operates on a closed, single-entity model exempt from standard transfer policies.

    Can I buy a .dclk domain name from Google?

    No, .dclk domain names are not for sale to the public under any circumstances. The TLD is a closed brand extension, meaning Google reserves all second-level domains for its own internal use. There is no marketplace, registrar, or reseller through which these domains can be purchased, as the registry's application to ICANN explicitly stated it would not make domains available to the general public.

    What dispute policies apply to .dclk domains?

    Standard dispute resolution policies like the Uniform Domain-Name Dispute-Resolution Policy (UDRP) do not apply, as there are no third-party registrants. Since Google is the sole entity that can register domains, any potential naming conflicts or trademark issues are handled internally by the company. The closed nature of the TLD means external parties cannot file claims against domain registrations.

    Why did Google create a .dclk TLD?

    Google created the .dclk TLD to establish a dedicated and secure namespace for its DoubleClick advertising technology services. This allows for clear branding and organization of its ad-serving platforms, tools, and related infrastructure. A separate TLD helps Google innovate and manage these services within a specialized environment, distinct from its other online properties and consumer products.
