A domain marketplace — also called a domain aftermarket — is a platform where registered domain names are listed for resale by their current owners. Unlike 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 DNSChkr 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.
DNSChkr 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 — DNSChkr does not act as an intermediary and does not take commissions on sales.

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:
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.
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.
