Summary

Preferred Mutual Insurance Company

United States of America · AI-generated

business insurance corporate

PREFERREDMUTUALINSURANCECOMPANY is the autonomous system for Preferred Mutual Insurance Company, a property and casualty insurer.

What it's used for

  • The address space carries corporate infrastructure, with registrants including Verizon Business (netname FRONTIER-COMMUNICATIONS) and Centrilogic, Inc. (netname CENTRILOGIC-CANADA).
  • The AS announces 512 IPv4 addresses across 2 prefixes, with 3 observed neighbours, indicating a small-scale internal corporate estate rather than a transit or access network.

Notable

  • Registrants differ from the announcer, with Verizon Business and Centrilogic, Inc. holding the prefixes, suggesting leased space or post-acquisition history.
  • The address inventory consists of two /24 blocks, one in the 50.49.254.0/24 range and one in the 173.240.11.0/24 range, with no IPv6 prefixes announced.

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.
