Search and browse millions of domains listed for sale across Afternic, Sedo, Dan.com, Porkbun, and more. Filter by TLD, marketplace, price, and domain length.
A domain marketplace — also called a domain aftermarket — is a platform where registered domain names are listed for resale by their current owners. Unlike ICANN-accredited registrars that sell new, unregistered domain names at standard registration prices, aftermarket platforms facilitate the secondary market for domains that someone already owns. Domain aftermarket prices are set by sellers based on factors like domain length, keyword value, TLD desirability, existing traffic, and comparable sales history. Prices range from under $10 for bulk inventory to millions for premium one-word .com domains — the most expensive publicly reported sale was Voice.com at $30 million in 2019. The DNS Checker Domain Marketplace aggregates listings from 16 aftermarket platforms into a single searchable interface, currently indexing over 12 million domains for sale with daily updates sourced from DNS zone file analysis of 240 million domain records.
How Does the DNS Checker Domain Marketplace Work?
DNS Checker identifies domains listed for sale by processing DNS zone file data from over 1,900 TLDs daily. The system cross-references nameserver patterns, marketplace API feeds, and registrar data to detect which domains are currently offered on aftermarket platforms. Search results can be filtered by TLD, marketplace source, price range (where EPP status codes and marketplace APIs provide pricing), and domain character length. All buy links point directly to the original marketplace listing — DNS Checker does not act as an intermediary and does not take commissions on sales.
Domain Marketplace Comparison
Each aftermarket platform serves different segments of the domain market. The following comparison covers the 16 platforms tracked by DNS Checker:
Domain aftermarket prices are set by sellers based on a combination of objective and subjective factors. The most significant pricing factors, according to industry data from NameBio (which tracks over 1.5 million historical domain sales), include:
Brandability — pronounceable, memorable, easy-to-spell names with no trademark conflicts.
Existing traffic and backlinks — domains with type-in traffic or backlink profiles from authoritative sites are valued higher.
Comparable sales — historical sales of similar domains establish market expectations. Tools like NameBio and DNJournal publish verified sale prices.
What Is the Difference Between Buy Now and Make Offer?
A Buy Now (BIN) listing has a fixed price set by the seller — the buyer pays the listed amount and the domain transfer initiates immediately under ICANN's Inter-Registrar Transfer Policy (IRTP). Make Offer domains allow price negotiation, with transactions typically settling at 10–30% of the initial asking price. Some platforms like Dan.com also support lease-to-own arrangements where buyers pay in monthly installments over 2–60 months. Expired domain auctions — offered by platforms like DropCatch and Aftermarket.com — allow competitive bidding for domains whose registration has lapsed and entered the deletion cycle. Closeout auctions (expiring domains without bids) can yield domains at $10–15, while competitive auctions for desirable expired names reach thousands.
Is It Safe to Buy Domains on Aftermarket Platforms?
Major aftermarket platforms provide buyer protection through escrow services and dispute resolution processes. Afternic, Sedo, and Dan.com all hold buyer funds until the domain transfer is verified complete. Before purchasing an aftermarket domain, it is advisable to verify that the domain is not subject to active UDRP (Uniform Domain-Name Dispute-Resolution Policy) proceedings at WIPO, check WHOIS history for clean ownership records, and confirm the domain is not flagged for spam, malware, or phishing activity. DNS Checker links directly to the original marketplace listing for each domain — the purchase transaction happens entirely on the marketplace platform with its buyer protection policies.
Frequently Asked Questions
What is a domain marketplace?
A domain marketplace (also called a domain aftermarket) is a platform where registered domain names are listed for resale by their current owners. Unlike registrars such as GoDaddy or Namecheap that sell new, unregistered domains, marketplaces facilitate the secondary market — selling domains that someone already owns. Major domain marketplaces include Afternic (owned by GoDaddy, the largest with 8.9 million listings), Sedo (established 2001, strong in ccTLDs), and Dan.com (acquired by GoDaddy in 2022, known for installment payments). Domain prices on aftermarket platforms range from under $10 for bulk inventory to millions for premium one-word .com domains. The most expensive publicly reported domain sale was Voice.com at $30 million in 2019.
How does the DNS Checker Domain Marketplace search work?
DNS Checker aggregates domain listings from 16 aftermarket platforms into a single searchable index updated daily. The system processes over 240 million DNS zone file records to identify which domains are currently listed for sale by cross-referencing nameserver patterns, marketplace API feeds, and registrar data. Search results can be filtered by TLD (.com, .net, .org, etc.), marketplace source, price range (where Buy Now pricing is available), and domain length. All buy links point directly to the original marketplace listing — DNS Checker does not act as an intermediary or take commissions on sales.
What is the difference between a domain marketplace and a domain registrar?
A domain registrar (accredited by ICANN under the Registrar Accreditation Agreement) sells new, previously unregistered domain names at standard registration prices, typically $8-15/year for a .com. A domain marketplace facilitates the resale of already-registered domains at prices set by the current owner, which can range from $10 to millions depending on the domain's perceived value. Some companies operate both: GoDaddy is both an ICANN-accredited registrar and owner of the Afternic marketplace, while Porkbun and Dynadot are registrars that also run their own marketplace listings. The key distinction is that registrar pricing is standardized by the registry operator (e.g., Verisign sets the .com wholesale price), while marketplace pricing is determined by supply and demand.
Which domain marketplace has the most listings?
As of March 2026, Afternic leads with approximately 8.9 million domain listings, making it the largest domain aftermarket platform by volume. Afternic is owned by GoDaddy and benefits from integration with GoDaddy's registrar platform and its Domain Discount Club. Porkbun follows with approximately 1.6 million listings, many offered through their registrar marketplace feature. Sedo, one of the oldest platforms (founded 2001 in Cologne, Germany), lists approximately 650,000 domains with particular strength in European ccTLDs. Dan.com (acquired by GoDaddy in 2022) lists approximately 265,000 domains and is known for its buyer-friendly installment payment option. DNS Checker tracks all 16 platforms simultaneously, allowing side-by-side comparison of listings across Afternic, Porkbun, Sedo, Dan.com, Atom, Efty, Squadhelp, BrandBucket, Bodis, Sav, Dynadot, DropCatch, Brandpa, Aftermarket.com, NameSilo, and BrandRoot.
How are domain aftermarket prices determined?
Domain aftermarket prices are determined by the seller based on several factors: domain length (shorter domains command higher prices — single-word .com domains regularly sell for $10,000-$1,000,000+), keyword commercial value (domains containing high-CPC keywords like 'insurance' or 'loans' are more valuable), TLD desirability (.com dominates at 70%+ of aftermarket sales by value), brandability (pronounceable, memorable names), existing traffic (domains with type-in traffic or backlinks), and comparable sales history. Platforms like NameBio and DNJournal track historical domain sales data for price benchmarking. Buy Now (BIN) prices are fixed by the seller, while Make Offer domains allow negotiation — typically settling at 10-30% of the initial asking price. Some marketplaces like Dan.com also support lease-to-own arrangements where buyers pay in monthly installments.
What are brandable domains?
Brandable domains are invented or creative domain names designed to serve as company or product names rather than targeting exact-match keywords. Examples include names like Squadhelp.com, Brandpa.com, or similar coined words that are short, memorable, and easy to spell. Platforms like BrandBucket (145,000+ listings) and Squadhelp (151,000+ listings) specialize exclusively in curated brandable domains, often including logo designs and brand identity packages. Brandable domains typically sell for $1,000-$10,000 and are popular with startups that need a unique, trademarkable name. Unlike keyword domains (e.g., CheapFlights.com), brandable domains have no inherent search traffic but offer stronger trademark protection and brand differentiation.
Is it safe to buy domains from aftermarket platforms?
Major domain aftermarket platforms provide buyer protection through escrow services and dispute resolution processes. Afternic, Sedo, and Dan.com all use escrow or escrow-like payment processing where the buyer's funds are held until the domain transfer is verified complete. ICANN's Inter-Registrar Transfer Policy (IRTP) governs domain transfers between registrars, requiring authorization codes (auth-EPP codes) and a 5-day transfer window. Buyers should verify that the domain is not subject to legal disputes (check UDRP/URS history at WIPO), is not on any trademark watchlists, has clean WHOIS history, and is not associated with spam or malware activity. DNS Checker links directly to the original marketplace listing for each domain — the purchase transaction happens entirely on the marketplace platform with their buyer protection policies.
What is the difference between a domain auction and a Buy Now listing?
A Buy Now (BIN) listing has a fixed price set by the seller — the buyer pays the listed amount and the transaction proceeds immediately. A domain auction allows multiple buyers to bid competitively over a set time period, with the highest bidder winning the domain. Some platforms support both: Sedo runs weekly domain auctions alongside fixed-price listings, DropCatch specializes in auctions for recently expired domains, and GoDaddy Auctions handles both formats. Expired domain auctions occur when a domain's registration lapses and enters the deletion cycle — registrars offer these domains at auction before they become available for new registration. Closeout auctions (domains expiring without bids) can yield domains at $10-15, while competitive auctions for desirable expired domains can reach thousands. DNS Checker currently indexes Buy Now listings and Make Offer domains; auction data is not yet tracked.
