AS7715 INET-GSB-TH - GSB

INET-GSB-TH belongs to GSB — the Government Savings Bank of Thailand, a state-owned retail bank supervised by the Ministry of Finance. The handle pairs the bank's initials with INET (Internet Thailand Company Ltd.), the provider that administers the ASN on its behalf.

What it's used for

• A single /24, 61.19.222.0/24, registered in APNIC as GSB-NET with the description "Government Saving Bank" and an abuse contact at gsb.or.th. That registration is what confirms the holder; the bare GSB in the AS description would otherwise be ambiguous.
• The AS is a leaf: it has one upstream and no downstream networks. It exists so the bank can multi-home or hold its own routing identity, not to provide service to anyone else.
• The /24 is an ALLOCATED NON-PORTABLE block, meaning it comes out of the upstream provider's larger allocation rather than being the bank's own portable assignment.

Notable

• This is corporate address space for a bank, not consumer or hosting space. There are no subscriber-style reverse DNS names anywhere on it, and no public reverse DNS at all on the addresses sampled — which is exactly what a locked-down financial network looks like.
• Do not read the "Government" in the name as a government agency network. GSB is a commercial retail bank that happens to be state-owned; it runs branches and savings accounts, not public administration.

Interesting

• The Government Savings Bank traces back to a 1913 royal act of King Vajiravudh that set up a "Savings Office" to introduce Thais to banking. It became the Government Savings Bank in 1947 and now runs over a thousand branches — all served, on the internet, from a network small enough to fit in a single /24.
