Summary

United States of America · AI-generated

retail grocery corporate st-louis

The AS handle DIERBERGS is held by Dierbergs.

What it's used for

  • The address space carries corporate infrastructure for a grocery retail chain, evidenced by the netname DIERBERGS-MARKETS and registrant Dierbergs.
  • The AS announces 256 IPv4 addresses within a single /24 prefix (205.151.113.0/24) 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 internal corporate communications, point-of-sale systems, and web endpoints for the St. Louis-based grocery retailer.

Notable

  • The RDAP registrant Dierbergs and netname DIERBERGS-MARKETS align directly with the AS holder and the operator's public identity.
  • Dierbergs is a long-standing grocery chain in the St. Louis metropolitan area, operating markets, pharmacies, and bakeries since 1854.
  • The inventory consists of a single contiguous /24 block, typical of a corporate estate managing its own IP space for store and headquarters connectivity.

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: 455 networks and 1,854 prefixes, as published 2026-11-09. 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.
