DOMAIN EXTENSION GUIDE

.protocol Domain Names

Prelaunch; not yet delegated

The.protocol string is associated with a proposed generic top-level domain application context and a technical term that suggests protocols, infrastructure and systems design. Publicly announced information identifies Link Freedom Group as the applicant associated with.protocol. ICANN has said the 2026 new gTLD application window closed on 12 August 2026 and public application details will be revealed after administrative review, so this guide reflects a prelaunch status rather than live domain availability.

Illustrative uses

What could a .protocol domain be used for?

If delegated in future,.protocol could suit projects built around standards, connectivity and digital infrastructure.

Developer documentation hubsA natural fit for sites that organise protocol references, implementation notes and release information.
Infrastructure product pagesUseful for services built around networking, messaging, identity or interoperability tooling.
Standards and specification projectsWell suited to communities publishing technical standards, drafts and explanatory material.
Protocol testing and demosCould support test environments, sandboxes and proof-of-concept deployments.
Open-source protocol initiativesA clear match for collaborative software projects focused on network protocols or data exchange.
Systems architecture portfoliosAppropriate for architects, consultants and labs presenting infrastructure design work.
Technical community eventsCould host conferences, working groups, workshops and session archives.
Machine-to-machine servicesA relevant choice for platforms that emphasise APIs, automation and structured communication.

Frequently asked questions

Is.protocol live?

It should be treated as prelaunch unless and until ICANN publishes a delegated, live status for the string.

Who is associated with the.protocol application?

Publicly announced information identifies Link Freedom Group as the applicant associated with.protocol.

What kind of website suits.protocol?

It is a strong thematic fit for technical documentation, infrastructure products, standards work and protocol-related services.

Can I register a.protocol domain now?

Not from the evidence available here. Availability depends on delegation and launch status, not on the existence of an application alone.

Why would a technical project choose.protocol?

It can provide an immediate signal that the site relates to systems, interoperability, communications or technical standards.
