About this network

KASIKORNBANK-AS-AP is Kasikornbank Public Company Limited (KBank), one of Thailand's largest commercial banks. AS7630 is the bank's own corporate network.

What it's used for

• Around 14 /24s spread across 203.146.x, 203.148.x, 210.1.x, 210.86.x, 49.231.x, 58.137.x, 103.151.x and 110.170.x, plus one IPv6 /48 — roughly 3,500 addresses.
• Reverse DNS is unmistakably the bank's own: names such as outbound20.kasikornbank.com mark mail and egress systems, and ucenteruat.kasikornbank.com is a user-acceptance-testing environment. No subscriber pools, no hosting tenants.

Notable

• Financial-sector enterprise space. Traffic from these addresses is bank systems and bank staff. It should not be geolocated to a datacentre pool or a consumer network.
• The registry contact is the KBTG Building in Pak Kret, home of KASIKORN Business-Technology Group, the bank's in-house technology arm — which is consistent with the bank running its own routed network rather than sitting behind a provider.

Interesting

• The presence of a publicly reachable, publicly named UAT host on a bank's production ASN is the kind of detail that only reverse DNS reveals. Non-production environments on internet-routable bank space are common and are worth knowing about, but they are not evidence of anything other than how the network is laid out.
