About Top-Level Domains
Generic TLDs (gTLD)
Open-registration extensions like .com, .net, .org, and newer ones like .io and .app, managed by ICANN-accredited registries.
Country-Code TLDs (ccTLD)
Two-letter extensions assigned to countries and territories — .uk, .de, .jp, .au. They signal geographic relevance and boost local SEO.
Sponsored TLDs (sTLD)
Restricted extensions for specific communities: .gov for US government, .edu for accredited institutions, .mil for military. Eligibility requirements apply.
Infrastructure TLD
.arpa is the sole infrastructure TLD, reserved for technical internet functions such as reverse DNS lookups and protocol address-to-name resolution.
Frequently Asked Questions
How many top-level domains exist?
As of 2025, ICANN's root zone database lists over 1,500 active TLDs — including legacy gTLDs like .com and .net, hundreds of new gTLDs introduced since 2013 (e.g. .app, .shop, .cloud), and around 300 country-code TLDs. This page lists all currently active delegations.
What is the difference between a gTLD and a ccTLD?
A gTLD (generic top-level domain) is generally open to anyone worldwide — examples include .com, .org, .net, .io, and .app. A ccTLD (country-code TLD) is a two-letter extension assigned to a specific country or territory (e.g. .uk for the United Kingdom, .de for Germany) and may have local residency or presence requirements.
Which TLD is best for SEO?
Google treats all gTLDs equally in global search rankings. Country-code TLDs (ccTLDs) may provide a geographic relevance signal for local searches. .com remains the most widely recognised and trusted extension internationally. Ultimately, content quality, backlinks, and site authority matter far more than TLD choice for SEO.
How can I look up WHOIS for a TLD?

Who manages TLDs and what is ICANN?
ICANN (Internet Corporation for Assigned Names and Numbers) is the non-profit that coordinates the global DNS and delegates each TLD to a registry operator. For example, Verisign operates .com and .net, while Public Interest Registry operates .org. Country-code TLDs are managed by designated national organisations.
