gTLD (generic Top-Level Domain)

The internet's top-level domains split into two camps:

• gTLDs (generic): not affiliated with any country. .com, .org, .net, .info, .biz were the original set; ICANN's 2012-2014 New gTLD Program expanded this to 1000+ including .app, .shop, .bank, .law, .io, .ai (the last two are technically ccTLDs but used as gTLDs in practice).
• ccTLDs (country code): two-letter codes corresponding to ISO country codes. .us (United States), .uk (United Kingdom), .de (Germany), .ca (Canada), etc. Each ccTLD registry sets its own rules (residency requirements, pricing, dispute policies).

Modusdom sells both. We have inline ccTLD rules built into checkout (e.g., .us requires a US Nexus declaration; .nyc requires NY residency and disallows P.O. boxes).
