Summary

Fishback Financial Corporation

United States of America · AI-generated

business finance corporate

FISHBACK is the autonomous system for Fishback Financial Corporation.

What it's used for

  • The address space carries corporate infrastructure, evidenced by netnames NET-96-2-250-0-24 and FIRST-BANK-AND-TRUST.
  • The AS announces 512 IPv4 addresses across 2 prefixes with 2 observed neighbours, indicating a small, self-contained corporate estate rather than a transit or access network.
  • Traffic from this AS consists of internal office workers and banking systems for a regional financial institution headquartered in Brookings, South Dakota.

Notable

  • Registrants align with the announcer, listing FISHBACK FINANCIAL CORPORATION for the 96.2.250.0/24 block and First Bank & Trust for the 216.249.217.0/24 block.
  • The inventory is finely subdivided into two /24 prefixes, consistent with site-by-site segmentation for a 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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
