Finding Expired Domains by TLD: .com, .io, .ai, ccTLDs
Where you find expired domains depends almost entirely on the letters after the dot. The .com machine is enormous, standardized and brutally contested. The .io world runs through a handful of specialist catchers. The .ai registry abolished free drops entirely and auctions everything. And country-code TLDs answer to their own registries, some of which delete names with no safety net at all. This guide maps the sources and the quirks, extension by extension, so you hunt each pool with the rules that actually govern it.
Which sources cover which TLD?
| TLD | Where expired inventory surfaces | Key quirk |
|---|---|---|
| .com / .net | Aggregators, registrar expiry auctions, daily drop lists, backorder services | Drops daily around 2:00 pm US Eastern; the largest and most contested pool |
| .io | park.io and rival catchers, aggregator .io tabs | $99 flat backorder, pay only on catch, 10-day auction if contested |
| .ai | Official Namecheap expiry auctions, registry DropZone for unsold names | Never free-drops; 2-year minimum registration and renewal |
| .uk | Nominet-governed release after suspension, UK catcher services | Roughly 90-day suspension, then rate-limited, equal-chance catching |
| .de | DENIC deletions, local catchers and monitors | No standard redemption; deletes can be near-instant |
| Other ccTLDs | Registry deletion lists, local registrar auctions, aggregator ccTLD filters | Every registry sets its own lifecycle; read the policy before spending |
.com and .net: the firehose
Scale first: Verisign's Q4 2025 Domain Name Industry Brief counts 161.0 million .com registrations out of 386.9 million domains worldwide, and daily expired inventory runs from roughly 100,000 listed expiring names to 200,000+ deletions depending on what you count. Deleting .com and .net names release daily around 2:00 pm US Eastern, and the whole ecosystem is built for that moment: GoDaddy adds 35,000+ new expiring domains to its auctions every day with closeouts from about $5, Dynadot walks unsold names down its closeout ladder of roughly $30, then $15, then $5, and DropCatch sells backorders at $13-59 backed by 1,200+ registrar accreditations for the drop itself. Since GoDaddy retired its own backorder product on October 7, 2025, catching a .com at the drop belongs entirely to the specialist services, and GoDaddy's February 2026 terms update removed some bidder protections besides, a reminder that auction-side rules shift and deserve a reread every season. The volume is unreadable raw, which is why .com hunting is really filter craft; our ranking of nine discovery methods applies to this pool most directly.
.io: the catcher's TLD
.io runs on Identity Digital registry infrastructure and has a drop ecosystem of its own, anchored by park.io, the classic .io catcher: $99 flat per backorder, you pay only if the catch succeeds, and contested names go to a 10-day auction among the backorderers. Demand stays structural because developer culture adopted the extension, with roughly 18% of Y Combinator startups using a .io as of recent counts. Supply events happen too: in June 2025 the registry auctioned a tranche of held-back premium .io names through GoDaddy. Treat .io like .com with a smaller, more specialized catcher pool, and expect the good short names to be contested.
.ai: no free drops, ever
.ai is the extension where normal hunting instincts fail hardest. Expired .ai names never free-drop. After a grace window of roughly 31 days, with no guaranteed redemption period, they route into official expiry auctions run daily through Namecheap since February 2025, and whatever goes unsold enters the registry's DropZone system. Registrations and renewals carry a 2-year minimum, so holding costs are double what a .com hunter budgets. The market justifies the attention: .ai grew from about 40,000 registrations in 2020 to roughly 859,000 by August 2025, expired .ai auctions have cleared $600,000+ in a single month, and the extension accounted for around 29% of 2025's top-100 public sales. Hunt it through the official channel and never place a conventional backorder waiting for a public drop that will not come. The registry has every incentive to keep it this way: Anguilla collected roughly US$85 million from .ai in 2025, so the professionalized expiry pipeline is policy, not accident.
ccTLDs: read the registry before you spend
Country codes are 145.6 million domains of the global total, and no two registries age their names identically. .uk names pass through a Nominet-governed suspension of roughly 90 days after expiry before release, and catching happens through rate-limited polling that gives every registrar tag a roughly equal chance, so no service can simply buy dominance. .de sits at the other extreme: DENIC has no standard redemption safety net and deletions can be near-instant once submitted, which makes monitoring matter more than drop-second speed. Other registries publish daily deletion lists, run their own auctions or release names on fixed schedules. The rule that generalizes: before hunting any ccTLD, read its lifecycle policy, because assuming the .com timeline is how hunters waste backorders on names that were never going to drop.
The prize for doing that homework is real. NameBio's 2025 full-year data showed ccTLD sales dollar volume up 61% year over year, the fastest-growing slice of a market that logged about 190,300 recorded sales overall, so the extensions with the most awkward rules are also where value is compounding quickest. Thin catcher pools plus rising demand is the classic setup for patient hunters willing to read registry policy in a second language.
One dashboard or many tabs?
Catching stays per-TLD: park.io for .io, Namecheap for .ai, national services for ccTLDs. Discovery is where you can centralize. ExpiredDomains.net tracks 676 TLDs free once registered, which makes it the widest single net; our free methods roundup shows how far that goes. DomCop aggregates drops and auction streams across extensions with Majestic and Moz metrics for filtering, from roughly $68 per month as of mid-2026 with a 2-day money-back guarantee and no free trial. And when a contested name spans ecosystems, Catch.Club routes a single backorder through 10+ catching platforms at once, while Gname brings 500+ registrar accreditations of its own to the catching side. Niche-specific filtering works the same across all of them, a craft covered in niche filters that work.
Frequently asked questions
Do expired .ai domains ever drop for free?
No. Since the Namecheap deal took effect in February 2025, expired .ai names go to official daily expiry auctions, and unsold names enter the registry DropZone. Budget for auction prices plus the 2-year minimum registration.
Where do I find expired .io domains?
park.io remains the anchor: $99 flat per backorder, paid only on success, with a 10-day auction if several people backordered the same name. Aggregators and ExpiredDomains.net both carry .io filters for the discovery side.
Are ccTLD drops less competitive than .com?
Usually, because the catcher pool is thinner and language barriers filter out casual hunters. The trade-off is registry risk: .de has no standard redemption and some registries delete with little warning, so the discount comes with sharper rules.
Which TLD should a beginner hunt first?
.com. The lifecycle is standardized, the tooling is mature, every guide applies to it, and liquidity is unmatched if you later sell. Specialize into .io, .ai or a ccTLD once the fundamentals are boring.
