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.

Frequently Asked Questions

Why do renewal prices differ so much between TLDs?

Each TLD is operated by a different registry that sets its own wholesale price, and registrars add their margin on top. Legacy TLDs like .com have price caps rooted in ICANN agreements, while country-code TLDs like .ai and .io set prices independently — which is why they cost several times more to renew.

Do all TLDs have the same expiration process?

No. The common pattern for gTLDs (auto-renew grace, then ~30-day redemption, then 5-day pendingDelete) comes from ICANN policy, but country-code TLDs like .ai, .io, and .co follow their own registry rules, with different grace windows and drop mechanics.
