A domain registry is the organization that operates a top-level domain. It keeps the authoritative master database of every name registered under that TLD, runs the TLD’s name servers, and sets the wholesale price that registrars pay. For example, Verisign is the registry for .com; Public Interest Registry is the registry for .org.
When you buy a domain, you deal with a registrar — the retail shop. But behind that shop stands the registry: the wholesaler that actually owns and runs the extension. Understanding the registry clears up a lot of confusion about who controls what.
What is a domain registry?
A registry is the single operator responsible for one or more top-level domains. Think of a TLD like .com as a giant ledger of names; the registry is the institution that owns and maintains that ledger. Nobody can register an example.com without it ultimately being written into Verisign’s .com registry.
The operator of a TLD. It holds the master database of all domains under that extension, runs the extension’s name servers, and sets wholesale pricing — working through registrars rather than selling to the public directly.
What does a domain registry do?
A registry has a focused but critical set of jobs:
- Maintains the master database. It records every registered name under its TLD, who holds it, and which name servers the domain uses.
- Runs the TLD’s authoritative name servers. These answer the question “where do I find
example.com?” by pointing resolvers to the domain’s name servers. - Sets wholesale pricing. Registrars pay the registry a per-domain fee; that wholesale price (plus the registrar’s margin) becomes your retail price.
- Enforces TLD policy. Any eligibility rules, reserved names or dispute procedures for the extension are administered by the registry under its agreement with ICANN.
Examples of registries by TLD
| Registry operator | Example TLD(s) |
|---|---|
| Verisign | .com, .net |
| Public Interest Registry (PIR) | .org |
| Google Registry | .dev, .app, .page |
| Radix | .tech, .online, .store, .site |
| GMO Registry | .shop |
| Country ccTLD operators | .us, .uk, .de — each run by a national registry |
Notice that one organization can run many TLDs, but each TLD has exactly one registry. The authoritative list of which organization sponsors each extension lives in the IANA Root Zone Database.
Registry, registrar, registrant: the chain
Three roles work together every time a domain is registered:
The three Rs
Registry = operates the TLD and holds the master list. Registrar = the retailer you buy from. Registrant = you, the person or organization that holds the domain. The registrar takes your order and writes it into the registry.

Where does ICANN fit?
Above the registries sits ICANN, the non-profit that coordinates the whole namespace. ICANN decides which TLDs exist, contracts with each registry to operate its extension, and accredits the registrars that may sell domains. Its IANA function maintains the root zone — the master file that points to every TLD’s registry. See who controls TLDs for the governance picture.
Why does the registry matter to you?
Even though you never deal with it directly, the registry shapes your experience: it sets the wholesale price (a major reason some extensions cost far more than others), defines any eligibility rules for the TLD, and ultimately guarantees that your domain resolves worldwide. When you choose an extension, you are choosing to live under that registry’s pricing and policies.
★ Key takeaways
- A registry operates a TLD and holds the master database of every name under it.
- It runs the TLD’s name servers and sets wholesale pricing.
- You buy through a registrar; the registry records the registration.
- Each TLD has one registry; ICANN coordinates them all via contracts and the IANA root zone.
Frequently asked questions
What is the difference between a registry and a registrar?
A registry operates an entire TLD and holds the master database of every name under it (wholesale). A registrar is the retail company that sells individual domains to the public and submits them to the registry. You buy from a registrar; the registry records the result.
Who is the registry for .com?
The registry for .com is Verisign, which also operates .net. Verisign maintains the authoritative .com database and runs the name servers that make every .com resolvable.
Can I register a domain directly with a registry?
Usually not. Most registries operate on a wholesale, “thick” model and do not sell to the public — they sell through accredited registrars. You register your domain with a registrar, which then records it in the registry on your behalf.
Does each TLD have its own registry?
Yes. Every top-level domain has a designated registry operator. One organization may run several TLDs — Verisign runs .com and .net; Radix runs .tech, .online and others — but each TLD has exactly one registry responsible for it.
What does a registry actually run?
A registry runs the authoritative database of registrations for its TLD and the TLD’s name servers — the servers that tell the world which name servers each domain uses. It also sets wholesale pricing and enforces the TLD’s policies under its ICANN agreement.
Why do some extensions cost so much more than others?
Largely because each registry sets its own wholesale price for its TLD. A legacy extension like .com has a low, stable wholesale rate, while a scarce, trendy or descriptive extension can be priced far higher by its registry. That registry-level price — plus the registrar’s margin — is why identical-looking domains differ so much in cost.
