Address King is a Korean link-directory site that organizes websites into popular categories and helps visitors find relevant destinations from one place. Its listings span entertainment, drama, nightlife, online communities, live sports, webtoons, torrents, site-verification services, betting, AI, shopping, finance, jobs, search engines, and other topics. Category pages feature ranked links, with popularity counts and recommendations intended to help users explore frequently visited sites.

A central service is keeping access information current. Address King says it responds quickly when listed websites change their addresses, using its own system to update links so users can more readily find sites they can no longer access. The site also presents recent link information, invites users to share recommendations, and provides search and favorites features. Visitors can browse the directory by category or review its featured top-ten lists, which cover everything from dramas and sports streams to communities, webtoons, and online stores. Address King positions itself as a convenient, continuously updated guide to popular Korean and international websites.
