AS11330 BANKPLUS-NETWORK-01

BANKPLUS-NETWORK-01 belongs to BankPlus, a community bank headquartered in Ridgeland, Mississippi with branches across the state. It is one of the smallest possible real ASes: RIS sees exactly 1 IPv4 prefix, 256 addresses, no IPv6, and 2 observed neighbours.

What it's used for

A single bank's internet edge. The one announced block, 64.32.45.0/24, is registered in ARIN to BankPlus itself under the matching handle BANKPLUS-NETWORK-01. The bank runs its own AS number rather than sitting on provider space for the ordinary reason a regional financial institution does: it wants two upstreams and a portable prefix so that online banking and branch connectivity survive the loss of either carrier without renumbering. Two observed neighbours is precisely that arrangement — dual-homed, not multi-homed at scale.

Notable

Everything about the inventory is first-party and consistent. There is no third-party registrant, no cross-registry space, and no sign of address blocks being announced on someone else's behalf. A /24 is also, in practical terms, the smallest prefix the global table will accept, which tells you this AS exists for resilience, not for capacity.

Interesting

Do not read the address count as a measure of the institution. A bank of this size has hundreds of internal hosts and dozens of branch sites, but they live on private RFC 1918 addressing and reach the internet through NAT; the public /24 only has to hold the public-facing pieces — VPN concentrators, mail, the perimeter of the online-banking stack, and whatever the bank exposes to its core-processing vendors. None of the two addresses we sampled returned a PTR, which is unremarkable and supports no inference in either direction. Financial-sector edge blocks like this are frequently stricter about what they publish than a typical enterprise.
