Summary

First Interstate Bank

United States of America · AI-generated

bank business internal

FIBXTERNALIP is operated by First Interstate Bank.

What it's used for

  • The space carries internal corporate infrastructure, evidenced by the netname FIBNETWORK and the registrant First Interstate Bank.
  • The AS announces 512 IPv4 addresses within a single prefix (74.114.2.0/23) and maintains 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of office workers and internal systems for a community bank headquartered in Billings, Montana, serving customers across the Western and Midwestern United States.

Notable

  • The RDAP registrant First Interstate Bank and netname FIBNETWORK align directly with the AS handle FIBXTERNALIP, confirming consistent ownership.
  • The address inventory is compact, consisting of a single /23 block, which fits the profile of a corporate estate with limited external footprint.

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: 442 networks and 1,779 prefixes, as published 2026-10-23. 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.
