About this network
SKNET-AS-KR is registered to SK Co., Ltd. — SK Inc., the holding company at the top of Korea's SK Group, whose C&C business division is the group's IT arm. SK Inc. C&C does systems integration, IT outsourcing and data-centre operation, historically for SK Group affiliates and increasingly for external enterprise and cloud customers.
What it's used for
- The SK Group corporate network and the systems SK C&C runs on its affiliates' behalf: managed enterprise applications, outsourced back-office and ERP estates, and the data centres those workloads sit in.
Notable
- The evidence points to a large enterprise / IT-outsourcing network rather than a carrier, and the two figures have to be read together. RIS observes 28 IPv4 prefixes carrying 131,072 addresses — a substantial estate — but only 6 observed neighbours.
- Six adjacencies against 131k addresses is decisive. A wholesale transit provider holding that much space would peer with hundreds of ASes; six is what a large end customer buys for redundancy. So this space is consumed by SK's own and its clients' systems, not resold.
- The footprint is anchored by a legacy 168.154.0.0/16 — a class-B-era block, the kind only an early corporate registrant holds — plus a set of /19s and /20s from Korean ranges (49.50.32.0/19, 211.45.32.0/19, 203.235.224.0/19, 203.242.64.0/21). Large aggregates rather than scattered /24s is the shape of a real operator's allocation history.
Interesting
- Beware the name. "SK" spans dozens of legally distinct companies; this AS is the holding company's IT network, not SK Telecom's or SK Broadband's consumer networks, which are separate ASNs entirely.
