A domain registrar is a company authorized to register domain names, such as yourcompany.com, on behalf of customers and to manage their renewal, transfer and settings. Each domain extension, such as .com, .org or a country code, is run by a registry that keeps the master list of names. Registrars sit between the registry and you, the registrant: they sell the registration, record your contact details, and let you choose which name servers answer Domain Name System (DNS) queries for the domain. Your domain underpins your website, email and many cloud services, so who controls the registrar account matters.
At a glance
- Registries run domain extensions; registrars sell and manage registrations; registrants hold the right to use the name.
- For generic extensions such as .com, registrars are typically accredited by ICANN; country-code extensions set their own rules.
- The registrar account controls renewals, contact details, transfer locks and which name servers the domain uses.
- Registration is not the same as DNS hosting, though many registrars offer both.
- Losing control of a domain, through expiry or account takeover, can take down email and websites.
What problem it solves
Domain names have to be unique and consistently recorded worldwide. Registrars provide the system for claiming, paying for and maintaining names without every organization dealing with every registry directly. They handle billing, renewals, contact verification and transfers, and they publish the name servers that tell the internet where to find your DNS.
For businesses, the registrar is also where domain risk concentrates. If a domain expires, is registered under a former employee’s personal account, or is hijacked through a weak login, email and websites can stop working or be redirected. Bringing domains under a company-owned registrar account with proper controls closes those gaps.
How it works
Registration. You search for an available name, choose a term (often one year or more), and provide registrant contact details. The registrar submits the registration to the registry and records you as the registrant.
Name servers and DNS. In the registrar account, you set the name servers for the domain. These may be the registrar’s own DNS service or another DNS provider. Records such as website addresses, mail servers and email authentication records (DMARC, SPF and DKIM) live with whoever hosts DNS.
Renewal and expiry. Registrations must be renewed before they expire. Many registrars offer auto-renew. After expiry, extensions and registrars typically have grace or redemption periods, with fees that vary.
Transfers. Moving a domain to a new registrar usually requires unlocking it and providing an authorization code. Some extensions block transfers for a period after registration or a previous transfer.
Security and privacy. Registrars commonly offer multi-factor authentication, transfer locks and, for some extensions, registry lock for extra protection. Public registration data may be redacted or offered with privacy services, depending on the extension and jurisdiction.
Treating domains as governed company assets, with named owners, access reviews and renewal records, fits naturally into a governance, risk and compliance program.
When it matters for buyers
- Ownership audits. Find every domain the business uses and confirm the registrant is the company, not an individual or agency; scattered registrations are a form of shadow IT.
- Mergers and acquisitions. Domains need to move to the acquiring company’s accounts, often with DNS and email cut-overs.
- Email deliverability and security projects. DNS changes for email authentication require access to the DNS host, which may be at the registrar.
- Staff or agency changes. When the person who set up the account leaves, make sure access and renewal notices move with the role.
Questions to ask vendors
- Is the account owned by the company, with role-based access and multi-factor authentication for every user?
- Are auto-renew and renewal notifications set up, and do notices go to a shared mailbox?
- Do you support transfer locks and registry lock for our key domains and extensions?
- Is DNS hosted here or elsewhere, and who has access to change it?
- What are renewal, transfer and redemption fees for each extension we hold?
- How do you handle support requests and verify identity for high-risk changes?
How it differs from DNS hosting
The registrar records who holds a domain and which name servers are authoritative for it. A DNS host runs those name servers and answers queries with your records, such as where your website and mail servers are. One company can do both, or you can register with one and host DNS with another. Problems at either can take a domain offline, but changes to the registrar account, such as name servers and ownership, carry the highest risk.
