域
U+57DF "域" CJK Unified Ideograph-# is a Chinese character that primarily means "region", "area", "territory", or "domain". It is composed of the radical "土" (earth or ground) on the left and a phonetic component "或" on the right, reflecting its original meaning related to a bordered or enclosed expanse of land. In modern usage, it appears in words such as "领域" (field or domain), "区域" (area or zone), and "地域" (district or locality), and it is also commonly used in technical contexts, such as the "域" in "域名" (domain name) for internet addresses.
