The .mobi domain emerged in 2005 when ICANN approved this specialized top-level domain to address the growing need for mobile-optimized websites. Initially backed by tech giants including Google, Microsoft, Nokia, Samsung, and Vodafone, the domain was managed by mTLD global registry. In 2010, Afilias acquired mTLD Top-Level Domain Ltd., and by 2017, .mobi transitioned to an unsponsored generic top-level domain.

The .mobi extension serves as a dedicated namespace for mobile websites, distinct from traditional domain extensions. Its primary purpose is to ensure optimal user experiences on mobile devices. When you see a .mobi domain, it signals that the website is specifically designed and optimized for smartphones and tablets.
