AS10181 KRS-AS-KR Korea Register of Shipping

KRS-AS-KR belongs to the Korean Register of Shipping, the national ship

classification society. KR surveys and certifies vessels against class rules and

international maritime conventions, and it is headquartered in Busan. It is a

non-profit technical body, but its network behaves like any other enterprise.

What it's used for

• KR's own services: surveyor and client portals, rule and certificate databases, e-learning, and the corporate systems that tie its Busan office to its worldwide network of survey stations.

Notable

• The kind is business (an enterprise network), and the evidence is first-party reverse DNS on its own space. Sampled addresses resolve to eclass.krs.co.kr and m.krcon.krs.co.kr — KR's e-learning and mobile service hostnames, on IPs KR announces itself. rDNS only ever tells you what space carries, not who holds it, but when the PTRs are the holder's own domain, the network is clearly being used for its registrant's own services rather than resold or leased out.
• The routing is small and coherent: RIS observes 4 IPv4 prefixes, 1,024 addresses and a single neighbour. Four consecutive /24s (103.12.248.0/24–103.12.251.0/24) from one APNIC allocation, behind one upstream. That is an organisation announcing its own contiguous block and buying transit from one provider.

Interesting

• The 103.12.248.0/22 range is a comparatively recent APNIC allocation, so unlike most of its neighbours in this ASN range, KR did not inherit a big legacy KRNIC block. It runs a modern, right-sized footprint.
