AS10196 — HNCBWORLD-AS-KR KOOKMIN BANK
AS10196 announces 5 IPv4 prefixes covering 1,280 addresses and 0 IPv6 prefixes.
About this network
HNCBWORLD-AS-KR is registered to Kookmin Bank, the largest retail bank in South Korea and the core subsidiary of KB Financial Group.
What it's used for
- The bank's own public network edge: internet and mobile banking, the certificate and authentication services Korean online banking depends on, card and payment gateways, corporate mail, and the transit links between its data centres and interbank clearing.
Notable
The routing table settles this as an enterprise network. RIS observes 5 announced IPv4 prefixes totalling 1,280 addresses, no IPv6, and just 3 observed neighbours. Three peers is a multi-homed corporate edge — enough upstreams that no single carrier failure takes online banking down, and nothing like the hundreds of neighbours a wholesale carrier accumulates. The address count is equally telling: 1,280 addresses would not number a single suburb of broadband subscribers, but it comfortably covers a bank's load balancers, VPN concentrators, mail gateways and DMZ.
The five prefixes are all /24s drawn from five unrelated parent blocks (210.179.238.0/24, 115.21.22.0/24, 203.248.188.0/24, 218.55.246.0/24, 1.224.38.0/24). For an operator that is scattered; for a decades-old bank that has absorbed other institutions and taken assignments from several upstreams over time, it is exactly what you would expect. They are announced by the bank itself, which is what distinguishes accretion from address brokering.
Interesting
HNCB is Housing & Commercial Bank — a separate institution that merged into Kookmin Bank in 2001. The bank is long gone; its AS handle is still here, a reminder that handles outlive holders.
