    摘要: A system has tags communicating by means of low frequency (below 1 megahertz) with routers which in turn communicate with nameservers. The tags have IP addresses, either explicitly programmed into the tags or associated in a virtual way with the tags. Lookups analogous to domain lookups permit human-friendly inquiries of tag status and location. Static (battery-backed) RAM in a tag permits great versatility in the localized function of the tag.
