TLD Reference for Domain Investors

Every TLD has its own registry, its own renewal economics, and its own rules for what happens when a domain expires. The differences are not trivia: a .com in redemption behaves nothing like an expiring .ai, and renewal prices range from about $10 to well over $100 per year depending on the extension.

These pages collect the facts investors actually need per TLD — who runs the registry, what renewals really cost, how the expiration lifecycle works, and when a dropping name becomes available. Policies change; where rules vary by registrar we say so, and the registry’s published policy is always the final word.
