About this network
DISC-AS-KR is registered to Daewoo Information Systems Co., Ltd., a Seoul-based IT services and systems integration company.
What it's used for
Daewoo Information Systems does systems integration, application development and IT operations for corporate customers. The AS carries the company's own network and the connectivity behind the systems it runs and hosts for clients, rather than consumer broadband.
Notable
The address footprint is large for a systems integrator, close to 96,000 IPv4 addresses, anchored on legacy space that predates the tight allocation policies of the modern APNIC era. Korean chaebol-affiliated IT arms picked up substantial address holdings in the 1990s when they were the group's in-house network builders, and those holdings largely persisted.
Interesting
The DISC handle is a fossil of the Daewoo Group, the conglomerate that collapsed in 1999. Several of its former subsidiaries continued independently, and the naming in the routing registry outlived the parent by decades.
