Businesses, brands, personal sites: general purpose

RDAP availability is taken from the IANA RDAP bootstrap file published on 2026-09-16; WHOIS server and delegation year from the IANA root zone database. Registry policies change: check the registry's own policy before relying on an eligibility rule.

What is .com?

.com is one of the original generic top-level domains added to the DNS root in 1985. It was meant for commercial organisations, but it has never been restricted in practice and became the default choice for businesses and personal projects alike. The registry is operated by Verisign under an agreement with ICANN.

Who can register it

Anyone can register a .com name through an ICANN-accredited registrar; there are no residency, company or documentation requirements. Names are allocated first come, first served.

WHOIS, RDAP and privacy

An RDAP service for .com (rdap.verisign.com) is published in the IANA RDAP bootstrap file. OrbitProbe reads registration data from it first, as structured JSON: registrar, creation and expiry dates, EPP status codes and nameservers. For gTLDs, personal contact data has been largely redacted from public output since the rules ICANN introduced in 2018 in response to the GDPR. In most lookups you will see redacted fields or the details of a privacy service instead of a registrant name. OrbitProbe only ever shows the organisation name and country.

FAQ

Who can register a .com domain?

Anyone can register a .com name through an ICANN-accredited registrar; there are no residency, company or documentation requirements. Names are allocated first come, first served.

How do I run a WHOIS lookup for a .com domain?

Type the name, in the form example.com, into the form on this page. OrbitProbe first queries the RDAP service of the .com registry (rdap.verisign.com). The result shows where the data came from and when it was observed.

Does .com support RDAP?

Yes. The IANA RDAP bootstrap file dated 2026-09-16 publishes rdap.verisign.com for .com. The classic WHOIS server is whois.verisign-grs.com.

Does .com support internationalised domain names (IDN)?

Yes, names containing non-ASCII characters can be registered under .com. Which characters are allowed is defined by the registry's IDN table. In the DNS such names are stored in Punycode form starting with "xn--"; OrbitProbe accepts either form.
