domainnimet

Domainnimet, or domain names, are identifiers used on the Internet to locate resources. A domain name provides a human-friendly address that maps to an Internet protocol (IP) address via the Domain Name System (DNS).

Domains are organized hierarchically: a top-level domain (TLD) such as .com, .org, or a country-code TLD like .fi; beneath it is a second-level domain chosen by the registrant. Together they form a fully qualified domain name (FQDN).

Registration and management are performed through registrars accredited by the governing bodies (for gTLDs, ICANN; for ccTLDs, national registries). Each domain is unique and can be registered for a fixed period, typically one to ten years, with renewal and transfer options. The registration data are publicly accessible via WHOIS in many jurisdictions, though privacy rules vary.

DNS translates domain names into IP addresses using records such as A (IPv4), AAAA (IPv6), CNAME, MX for mail, and TXT for various validations. DNSSEC adds cryptographic protection to prevent tampering with responses.

Domain names support branding and digital identity but are subject to policies on trademark, cybersquatting, and dispute resolution. Security best practices include enabling DNSSEC, using strong registrar authentication, and monitoring expiry dates to avoid unintentional loss.
