Summary

BancFirst

United States of America · AI-generated

business banking corporate

BANCFIRST is the autonomous system for BancFirst, a regional bank headquartered in Oklahoma City.

What it's used for

  • The address space carries internal corporate infrastructure, as indicated by the registrant BANCFIRST and netnames NETBLCK-OK-CB-24-248-117-0 and NETBLK-OK-CB-24-248-243-0.
  • The AS announces 512 IPv4 addresses across 2 prefixes and maintains 2 observed neighbours, a ratio consistent with a small, self-contained corporate network rather than a transit or access provider.

Notable

  • The RDAP registrants for both announced prefixes are BANCFIRST, which aligns perfectly with the AS holder.
  • BancFirst operates three subsidiary banks: BancFirst, Pegasus Bank, and Worthington Bank, all based in the United States.
  • The inventory consists of two /24 blocks, representing a modest and finely subdivided address estate typical of a single corporate entity.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 454 networks and 1,854 prefixes, as published 2026-11-06. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
