The following is a list of functioning Korean IDNs (Internationalized Domain Names). They all belong to the same Computer Repair Company. The TLD (Top Level Domain) used is 닷컴 which is Verisign's new Korean language equivalent to their com TLD. Each IDN contains 컴퓨터수리 which means Computer Repair. The only difference between these IDNs is the first two characters which are the names of South Korean cities. I think this is clever and creative use of IDNs!
The last two IDNs below are structured differently. The first two characters are, I think, a neighbourhood and the first two characters after the hyphen are the city.
The cities are: 시흥 Siheung, 부천 Bucheon, 창원 Changwon, 마산 Masan, 평택 Pyeongtaek, 오산 Osan, 진해 Jinhae, 김해 Gimhae, 부산 Busan.
Update 9th March 2017: Here is another family of Computer Repair 컴퓨터수리 IDNs with a different registrant.
