.ion
Is .ion a real TLD? Who’s applying to run it?
.ion is contested: 4 applications for it are on ICANN’s Reveal Day list, as of 7 October 2026. They are XYZ Registry, XServer, Identity Digital and Link Freedom Group. Qaten named .ion as a backup string for its .bit application. ICANN deactivated it, because another applicant applied for the same string or named it as a backup.
Who is applying, and what they run today
Two of the five already run TLDs, 26.76M names between them. One runs one of .ion's closest 2012 strings: Identity Digital .bio. DNRater, Link Freedom Group and XServer run none.
Will names sell?
A clever word-ending domain (vis.ion, mot.ion) with science-y charm, but a wordplay gimmick more than a serious home for most projects.
Last round the AI scored the 2012 strings blind to their fate. Strings it scored 60 or more hold a median 27,168 names today; those under 30, a median of 30. .ion’s closest 2012 strings hold .one 284K and .bio 69K.
The nearest 2012 strings, and how many names each holds today
The closest 2012 string, .one, held 283,638 names, June 2026. .bio held 69,202. Chosen by AI from every string in the 2012 round, without being told what happened to any of them.
- .est
Both bet that a short English word-ending is worth more as a suffix completing the second-level label (opt.ion, sess.ion / b.est, hon.est) than as a standalone category, so the buyer is any registrant hunting a clever short name rather than an industry.
Same bet on a tiny abstract English word with no vertical attached: value comes from brevity and tone, and the registry has to manufacture demand from startups and brand projects rather than harvest an existing category.
Also a three-letter scientific morpheme that reads as both a real word and a bound word-part, sold as an open generic whose registrants come for the science flavor plus short-string appeal, not because they belong to a defined trade.
Where they meet elsewhere
Identity Digital and XYZ Registry face each other in 77 contests this round, .ion included.
- Identity Digital × XYZ Registry
- Identity Digital × Link Freedom Group
- XYZ Registry × Link Freedom Group
- Identity Digital × XServer
- Link Freedom Group × XServer
wordplay-driven brands and startups wanting a name like vis.ion or fus.ion, plus battery, energy, and physics-adjacent companies; the applicant's crypto/web3 framing is a secondary crowd at best
What a .ion domain is
.ion is not a TLD yet. It is a string on our record of the ICANN 2026 new gTLD round, in our AI & tech category. 4 applications for it are on ICANN’s Reveal Day list.
Is the .ion domain extension real yet?
.ion 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 .ion domain?
You can’t yet. A .ion name can only be registered once the string is delegated (added to the DNS root) and its registry opens.
Is .ion a real TLD?
Not yet. .ion is not in the DNS root, so nothing resolves under it. It’s here because .ion is on ICANN’s Reveal Day list of applied-for strings. Every entry on this page links to its source.

“.ion · Crypto & Web3 · “Building blocks for big dreams.””Link Freedom Group
- Band chosen: 30-49, usable but limited. The string's core asset is the '-ion' suffix, one of the richest word-ending hacks in English (vision, motion, fusion, station, nation and many more), plus a genuine dictionary meaning (a charged particle) that gives it a science/energy brand flavor. By analogy, suffix-hack TLDs have produced real but shallow demand: .ly and .io showed hacks can seed adoption, but newer hack-oriented gTLDs have tended toward one-off vanity registrations and redirects rather than sustained primary-identity use, and I flag that as analogy since .ion has no market history of its own. It is not in the 50-69 band because there is no evident category where .ion would be a self-explanatory identity: the applicant files it under crypto/web3, but the string carries no inherent crypto meaning, and hack buyers are dispersed across categories, which caps sustained demand and aftermarket depth. It is above the 10-29 band because the hack surface is unusually large and the science/energy read gives non-gimmick registrants (batteries, propulsion, physics-adjacent tech) a plausible reason to use it as a real address, so demand should exceed pure joke/event TLDs. Applicant context, stated neutrally: the string was filed by Link Freedom Group, which filed more than 300 strings in the ICANN 2026 round and published its catalog ahead of Reveal Day; a very large portfolio suggests marketing attention per string may be spread thin, which tempers adoption likelihood but not the string's intrinsic quality. Main market uncertainty (launch assumed): whether hack-style registrations translate into primary-identity use and renewals, or remain redirect-and-lapse vanity buys, which is the difference between the top and bottom of this band over the next 5 years.
