Definition

A registry is the technical operator of a domain name extension (TLD). It maintains the central database of all domains registered under that extension and resolves DNS queries at the TLD level.

Examples

• Verisign: .com, .net
• Afnic: .fr and overseas extensions
• PIR: .org
• Nominet: .uk
• Donuts/Identity Digital: hundreds of new gTLDs

Registry vs registrar

A registrar is the commercial interface; the registry is the technical operator of the TLD. You buy a domain from a registrar, but the registry maintains the official records and signs the DNS zones.

Why it matters for brand protection

• Registration policies vary across registries (proof of use, geolocation, sector)
• Some registries offer advanced protection services (domain lock, brand blocks)
• ICANN accredits gTLD registries and sets common rules
• In severe disputes, the registry can be escalated to as last resort
