Summary

Dennis Group

United States of America · AI-generated

business enterprise food beverage

DENNIS-GROUP is the autonomous system for Dennis Group, a US-based design-build firm specializing in food and beverage manufacturing facilities.

What it's used for

  • The address space is registered under the netname DENNIS-GROUP for both announced IPv4 prefixes, indicating a corporate internal network rather than a public service provider.
  • The AS announces 1280 IPv4 addresses across 2 prefixes and 8 IPv6 prefixes, while maintaining only 5 observed neighbours. This low neighbour count relative to the address inventory suggests an internal corporate estate with limited external peering, consistent with a private business network.

Notable

  • The RDAP registrants for both the 142.249.168.0/22 and 23.184.184.0/24 prefixes align perfectly with the AS holder, Dennis Group.
  • The address inventory consists of one /22 block and one /24 block in IPv4, alongside a set of IPv6 prefixes under the 2602:819::/32 space, reflecting a standard corporate allocation.

Reputation

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 1,781 prefixes, as published 2026-10-16. 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.
