The following is a list of functioning Korean IDNs (Internationalized Domain Names). The TLD (Top Level Domain) used is 닷컴 which is Verisign's Korean language equivalent to their com TLD.
This family of Korean IDNs are concerned with Computer Repair 컴퓨터수리. The first two characters of the first 6 IDNs are names of Korean cities: 김포 Gimpo, 안양 Anyang, 용인 Yongin, 대구 Daegu, 파주 Paju, 성남 Seongnam. I think the first 2 characters of the next 2 IDNs are districts or neighbourhoods of 서울 Seoul: 용산 Yongsan, 종로 Jongno. The last one 일산 Ilsan, is a 동 neighbourhood of 고양 Goyang.
The following family of Korean IDNs all resolve to Fun Design website. I discovered this family at newly.domains/20171128-229 홈페이지제작 means home page creation. The first 2 Korean characters of the first 9 IDNs are Korean cities: 과천 Gwacheon, 광주 Gwangju, 대구 Daegu, 대전 Daejeon, 부산 Busan, 서울 Seoul, 수원 Suwon, 울산 Ulsan and 인천 Incheon.
