AS11275 NBH-HOLDINGS-CORPORATION

NBH-HOLDINGS-CORPORATION belongs to National Bank Holdings Corporation, the Colorado bank holding company behind NBH Bank and its regional brands, including Community Banks of Colorado, Bank Midwest and Hillcrest Bank. This is a bank's own corporate network, not a provider.

What it's used for

RIS observes two IPv4 prefixes carrying 512 addresses — 63.76.132.0/24 and 72.166.82.0/24 — no IPv6, and four observed neighbours. Two /24s and four neighbours is the shape of a regulated financial institution multihoming its internet edge: it buys transit from several carriers so that no single provider outage takes down online banking, and it originates its own space so the addresses that partners, core processors and payment networks have allowlisted stay stable across a change of carrier. It sells connectivity to nobody, and 512 addresses could not support anything else.

Branch and ATM connectivity for a bank of this size runs over private circuits, not public routed space. What these two /24s carry is the internet-facing estate: public web and online-banking front ends, VPN termination for staff and branches, secure file transfer, and inbound mail.

Notable

The two prefixes come from two different eras and two different carriers. 63.76.132.0/24 sits under UU-63-76-132 — a legacy UUNET handle — with the org recorded as NBH Holdings Corporation itself. 72.166.82.0/24 is a CTL- handle, meaning CenturyLink provider-assigned space, SWIPed to an org recorded as COMMUNITY BANKSHARES INC CHERR. A carrier SWIP reassignment to a named bank customer is not a third-party registrant in the leasing sense: this is provider-assigned space with a bank's name on the paperwork, and NBH's own brand family is full of community-bank names. Two prefixes, two carrier lineages, one institution.

Interesting

The address estate is a fossil of banking consolidation. NBH was built by acquiring community banks across Colorado, Kansas, Missouri, Texas and Utah, and the network it announces still carries a block registered under an acquired institution's name rather than its own.
