Companies that sell domain names fall into a handful of distinct types: accredited registrars that register available names, resellers such as web hosts and website builders that sell registrations on a registrar’s behalf, aftermarket marketplaces and brokers that sell names someone already owns, and expired-domain auction and drop-catch services that sell names as they lapse. A separate group sells blockchain-based names that sit outside the traditional domain system. Which kind of company you need depends on one question: is the name you want available to register, or does someone already own it?
The distinction matters more than most buyers realize. Each type of company plays a different role, follows different rules, and creates different risks. This guide explains what each one does, names representative companies in each category, and sets out what to check before you hand any of them your money or your brand.
How the Domain Market Is Structured
Every domain name lives in a top-level domain (TLD, the part after the last dot, such as .com or .org). Each TLD is run by a registry, the organization that keeps the authoritative list of names in that extension; Verisign runs .com, for example. Registries generally do not sell to the public. They sell through registrars, which are accredited by ICANN (the Internet Corporation for Assigned Names and Numbers) or, for country-code TLDs, by the national registry. Our guide to how domain name registrars work explains that relationship in detail.
The market is large. There were 386.9 million domain name registrations across all TLDs at the end of 2025, including 161.0 million .com names, according to Verisign’s Domain Name Industry Brief release of February 5, 2026. Most of the names people want in .com are already registered, which is why the aftermarket exists.
Registrars: Selling Names That Are Available
A registrar is the company that registers an available name in your name and manages it afterward. When you search for a domain and buy it new, you are buying from a registrar, directly or through a reseller. Well-known retail registrars include GoDaddy, Namecheap, Porkbun, Dynadot, Name.com, NameSilo, Hover and Cloudflare Registrar, and Squarespace took over the former Google Domains business in 2023. Corporate registrars such as CSC and MarkMonitor serve large brands with managed portfolios.
Registrars differ less in what they sell, since they all draw from the same registries, than in how they sell it and how they protect it. The differences that matter are renewal pricing, included WHOIS privacy, the strength of multi-factor authentication, availability of registry-level locks, the transfer process, and support when something goes wrong. Our comparison of the top domain name registrars sets those features side by side.
Resellers: Hosts, Builders and Agencies
Many companies that sell domain names are not registrars at all. Web hosts such as Bluehost, website builders such as Wix, Shopify and Squarespace, and many agencies and IT providers sell domains as resellers. They use a wholesale registrar’s accreditation and systems, set their own prices, and run their own dashboards. A lookup in RDAP (the Registration Data Access Protocol that replaced WHOIS for generic TLDs) shows the registrar of record, which may be a company you have never heard of.
Buying through a reseller is convenient, especially when a “free domain” comes with a hosting plan. The trade-offs are that the free period usually covers only the first year, renewal prices follow the host’s rate, and moving the domain later means working through the reseller’s process. When the reseller is a web developer or agency, the bigger risk is ownership: if the account is in their name, they control the domain.
Aftermarket Marketplaces: Selling Names Someone Already Owns
When the name you want is registered, the seller is its current owner, and marketplaces are where many owners list names for sale. Sedo, Afternic (owned by GoDaddy), Atom, GoDaddy Auctions and Flippa are among the best known. Listings are usually fixed-price (“buy it now”), make-offer, or auction. Many marketplaces syndicate listings to registrar search results, so a name marked “for sale” at checkout may be an aftermarket listing rather than a registry premium name.
Aftermarket pricing has a wide spread. In their Global Domain Report 2020, Sedo and InterNetX reported more than 19 million domains listed for sale at Sedo, an average 2019 sale of $2,284 and a median of $577.22, with .com accounting for 57% of sales. Those are 2019 figures, but the pattern holds: a small number of very expensive sales pull the average far above what a typical name sells for.
Escrow and Ownership Changes
A reputable marketplace holds the buyer’s payment in escrow until the domain has moved into the buyer’s control, either by a push to the buyer’s account at the same registrar or by a registrar transfer. Buyers should insist on that sequence and should not pay a private seller directly. Once the name arrives, change the registrant details, turn on multi-factor authentication, and remember that a new transfer generally triggers a 60-day lock against moving it again. Our guide to how to buy a domain that is taken covers the full process.
Brokers: Negotiating Private Sales
A domain broker represents a buyer or a seller in a private negotiation. Brokers are useful when a name is not listed, when the owner is hard to identify because registration data is redacted, or when the buyer does not want to reveal who is asking, since a known brand name tends to raise the price. Large marketplaces run brokerage desks, and independent brokers work on commission. A broker’s value lies in finding the owner, judging a realistic price, and closing through escrow. Ask how the broker is paid and whom it represents before you engage one.
Expired-Domain Auctions and Drop-Catch Services
When an owner fails to renew, a domain can be sold before or after it is deleted. Registrars often auction expiring names from their own customers, through platforms such as GoDaddy Auctions, NameJet and SnapNames. Names that reach deletion are caught by drop-catch services, which race to register them the moment they become available. Our guide to domain auctions explains how those sales work.
Drop-catching is an industrial business. A 2016 measurement found that drop-catch services control over 75% of accredited registrars, because each accreditation adds connections to the registry, and that 10.1% of deleted .com domains were re-registered on the day of deletion, according to Lauinger et al., WHOIS Lost in Translation (USENIX Security 2017). A separate nine-month study in 2017 found that only about 10% of dropped domains are caught at all, and that dropcatchers representing 0.03% of registrant clusters registered 60% of them, according to Miramirkhani et al., Panning for gold.com (WWW 2018). A valuable name that lapses is almost never available to its former owner by the time they notice.
Blockchain Naming Services
Companies such as Unstoppable Domains sell blockchain-based names, tied to cryptocurrency wallets, that are typically bought without annual renewal fees. These names are a different product. They do not resolve in standard browsers without additional software, they sit outside ICANN’s transfer and dispute policies, and control depends entirely on the wallet that holds them. They can complement a traditional domain but cannot replace one for a business website or email.
What to Check Before You Buy From Any Company
Whatever kind of company you buy from, the same checks protect you. These are the ones we recommend to every client.
- Confirm the domain will be registered in your organization’s own account and name, not a developer’s, agency’s or employee’s.
- Compare renewal prices, not first-year prices, and check whether a premium price applies at renewal.
- Turn on the strongest multi-factor authentication the registrar offers on the day you open the account.
- For an aftermarket purchase, use escrow and look into the domain’s ownership and usage history before you pay.
- Keep the account email on a monitored address so renewal and transfer notices reach a person.

Mistakes That Turn Into Recovery Cases
In the cases we handle, three mistakes recur. The first is buying a domain through a web developer who registers it in their own account; years later, the business discovers it does not control its own name. The second is buying an aftermarket domain without checking its history, only to find it was previously used for spam or malware, or was taken from its rightful owner. The domain history red flags are usually visible beforehand. The third is letting a name lapse in the assumption that it can simply be re-registered, when the drop-catch figures above show how little time that leaves.
How DNAccess Helps
DNAccess is not a registrar or a marketplace, and we are independent of the companies named in this article. If you own a domain name you want to sell, or want to approach the owner of one you want to buy, our domain name sales outreach service handles the outreach and negotiation. Before you buy a name on the aftermarket, our domain name background check reviews its ownership, registration and usage history so you know what you are acquiring. If a domain you own has been lost to expiration, theft or a developer dispute, we handle the recovery. More guides are in our Domain Name Basics section.
