An open [[tld|TLD]] is one with unrestricted registration policies, meaning any person or entity worldwide can register a domain name under it without needing to prove eligibility, nationality, or organizational affiliation. .com is the quintessential open TLD. Open TLDs contrast with [[restricted-tld|restricted TLDs]] (like .edu or .gov) and [[stld|sponsored TLDs]] that enforce eligibility rules. Many [[new-gtld|new gTLDs]] launched as open TLDs to maximize registration volume, though some open TLDs later introduced additional verification requirements to combat abuse.
Example
.com, .net, .org, .xyz, and .online are open TLDs — anyone can register a domain under them without providing eligibility documentation.
