.kernel
Is .kernel a real TLD? Who’s applying to run it?
Nobody has applied for .kernel in its own right, as of 8 October 2026. Identity Digital named .kernel as the replacement string of its .journey application. Identity Digital named .kernel as the replacement string of its .fix application. Identity Digital named .kernel as the replacement string of its .agent application.
A narrow developer-flavoured word: memorable for OS and systems projects, but most will keep .dev or .com as their main address.

No applications recorded for this TLD yet.
The 2012 applications making the most similar bet. Chosen by AI from every string in that round, without being told what happened to any of them.
Same bet as .kernel: a short piece of insider engineering vocabulary with no community or trademark owner behind it, sold on the premise that technical builders will put their primary identity on a word only their own trade uses fluently.
Same open-generic category bet aimed at the computing industry itself, but one rung broader and more marketable than a precise component noun, so it needs far less insider recognition to work.
Closest structural analogue for the narrowness: a precise technical-product noun whose plausible registrant pool is a handful of specialist vendors, meaning it must win a small expert audience rather than a mass market.
What a .kernel domain is
.kernel is not a TLD yet. It is a string on our record of the ICANN 2026 new gTLD round, filed under AI & tech. Nobody has applied for .kernel in its own right. It is named on ICANN’s list as part of an application for another string.
Is the .kernel domain extension real yet?
.kernel is not yet a domain extension you can register: nothing resolves under it, and no registrar sells names in it. Nobody has applied for it on the public record; the ICANN 2026 new gTLD round is the process that would decide whether it becomes one.
When can you buy a .kernel domain?
You can’t yet. ICANN publishes every applied-for string on Reveal Day, 7 October 2026 at 18:00 UTC. A .kernel name can only be registered after that, once the string is delegated and its registry opens. Last round's closest parallel to .kernel was .dev, delegated on 18 December 2014.
Is .kernel a real TLD?
Not yet. .kernel is not in the DNS root, so nothing resolves under it. It’s here because ICANN’s list names .kernel as part of an application for another string. Every entry on this page links to its source.

- Band chosen: 10-29 (vanity/narrow), at its top. .kernel is a real technical word with a clear developer connotation, so it is not a joke string, but its meaning is narrow: it points at operating-system internals and low-level systems work, plus a secondary 'core of something' metaphor and the grain/popcorn sense. Developer-facing generic TLDs that are broad (by analogy: .dev, .io) have become primary identities for serious projects; narrower descriptive tech strings run by the same kind of portfolio registry (by analogy: .software, .systems, .codes, .technology) have registered mainly at volume or on price with weak brand signal and a thin aftermarket. .kernel is narrower still than those, which is why it is not in the 30-49 band: I expect shallow, launch-driven interest from systems hobbyists, a handful of OS-adjacent projects, and defensive or playful registrations, with most developers keeping .dev, .io or .com as their main address and using a .kernel name as a redirect or side project at best. It is above the 1-9 band because the word is memorable, short to type, and has a genuine (if small) community that would understand it without explanation. On the record: a single standard (not brand/community/geographic) application by Identity Digital, filed as a replacement string for its .agent application, with no contention recorded; a portfolio operator of this kind generally brings wide registrar distribution, which supports reaching the niche but does not widen it. Main market uncertainty: whether the 'kernel' metaphor spreads beyond OS work into AI-agent and platform branding (a 'kernel' as the core of an agent runtime or product), which would broaden the buyer pool toward the usable-but-limited band.
