AS9276 CHINAE-AS-KR JT Chinae Savings Bank

AS9276 (CHINAE-AS-KR) is held by JT Chinae Savings Bank, a South Korean mutual savings bank in the J Trust group. This is a corporate end-site AS: a bank routing its own internet-facing edge, with no service-provider, hosting or transit function of any kind.

What it's used for

The evidence here is about as simple as an AS gets. AS9276 announces exactly one IPv4 prefix — 211.44.27.0/24, 256 addresses — no IPv6 at all, and has just one observed BGP neighbour. A single /24 behind a single upstream is the minimum viable BGP presence. A network of this shape is not multihoming for resilience and is not selling anything; it is an enterprise that obtained an AS number and a /24 so that its own public services (internet banking front ends, VPN concentrators, mail and similar) sit in address space it controls rather than in a provider's. Everything else the bank does runs behind that /24 or off-net entirely. Because a /24 is the smallest globally routable IPv4 block, this AS will never grow into anything else without new allocations.

Notable

• The bank's current identity is much newer than an AS number in the 9200s would suggest: the JT Chinae brand dates from the mid-2010s, when J Trust consolidated its Korean savings-bank businesses. The registry object has carried at least one renaming, so do not read the handle as a founding-era name.
• Traffic sourced from 211.44.27.0/24 is corporate banking infrastructure. It should never look like consumer eyeball traffic or hosting.
