.core
Is .core a real TLD? Who’s applying to run it?
.core is contested: 3 applications for it are on ICANN’s Reveal Day list, as of 7 October 2026. They are Identity Digital, ShortDot and Link Freedom Group. .top (Zhongze) named .core as a backup string for its .pop application. ICANN deactivated it, because another applicant applied for the same string or named it as a backup.
A real tech word that fits software and infrastructure projects, but likely a budget alternative to established endings, not a standard.
developer-tool, platform, and infrastructure teams naming an engine, SDK, or backbone service; secondarily brandable-name hunters who want a short techy suffix when the obvious endings are taken.
In LFG's published list of 300+ strings submitted before the ICANN window closed on 2026-08-12. Their catalog tagline: “The heartbeat of your project.”
One of the 80 strings ShortDot published for the ICANN 2026 round. ShortDot states it has submitted 40 applications, but publishes the 80 strings without revealing which 40 are applications and which 40 are designated replacements. The submission claim is therefore applicant-level, not string-level: nothing in the source says ShortDot applied for THIS string. Catalogued, not announced.
Named on the ICANN gTLD application list, 7 October 2026 as a replacement (backup) string of the applicant's .pop application, shown as deactivated: another applicant applied for the same string or named it as a backup
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: an abstract English quality word meaning "essential/first-rate" with no built-in registrant class, so it only works if sold as a brandable modifier to anyone wanting to signal primacy rather than to a defined industry.
Same bet in the positional-noun register - a generic word for the hub/middle that must earn registrations as the right half of descriptive compounds rather than from a community that already calls itself by that name.
Same bet as a short, semantically empty primacy word: no natural owner, value resting entirely on universal brandable appeal and left-of-dot pairing.
What a .core domain is
.core is not a TLD yet. It is a string on our record of the ICANN 2026 new gTLD round, in our Infrastructure category. 3 applications for it are on ICANN’s Reveal Day list.
Is the .core domain extension real yet?
.core is not yet a domain extension you can register: nothing resolves under it, and no registrar sells names in it. It is a string applicants have put forward in the ICANN 2026 new gTLD round, the process that decides whether it becomes one.
When can you buy a .core domain?
You can’t yet. A .core name can only be registered once the string is delegated (added to the DNS root) and its registry opens. Last round's closest parallel to .core was .prime, delegated on 7 June 2016.
Is .core a real TLD?
Not yet. .core is not in the DNS root, so nothing resolves under it. It’s here because .core is on ICANN’s Reveal Day list of applied-for strings. Every entry on this page links to its source.

“.core · Infra · “The heartbeat of your project.””Link Freedom Group
- Band chosen: usable but limited (30-49). The string is a genuine, widely used English tech word: software teams routinely name their central engine or base library the 'core' of the product, so 'name.core' parses instantly for an infra or dev-tools identity, and it also reads cleanly for AI-model and chain-infrastructure branding. It is not in the band above (strong niche, 50-69) because there is no visible category where projects currently reach for a core-flavored ending as a primary identity; 'core' is a modifier word, not a destination category buyers search for, and by analogy (flagged as analogy) comparable single-word tech generics from earlier new-gTLD rounds tended to sell at volume on price, with weak renewal-quality brand signal and thin aftermarkets, rather than becoming a default anyone had to own. It is not in the band below (vanity/joke, 10-29) because the semantic fit for serious software projects is real, volume registration demand is plausible, and a subset of infra products could credibly adopt it as a primary identity rather than a novelty. Applicant facts, stated neutrally: the applicant, Link Freedom Group, filed more than 300 strings in the ICANN 2026 round (the round's largest applicant per its voluntarily published list, press-corroborated 2026-08-13), and its catalog entry positions .core as category 'Infra' with the tagline 'The heartbeat of your project.'; a large-portfolio applicant implies .core would likely be marketed as one string among many rather than with dedicated category-building investment, which tempers adoption likelihood within the 5-year window. Main market uncertainty: whether developer and infra teams, whose naming habits are anchored to a small set of trusted incumbent endings, will treat any new generic suffix as acceptable for a primary production identity in the next 5 years, or keep new strings like .core in redirect and side-project roles.
