Summary

Intrado Life & Safety

United States of America · AI-generated

business public-safety enterprise

INTRADO is the autonomous system for Intrado Life & Safety, Inc.

What it's used for

  • The address space carries corporate infrastructure for a public safety technology provider, evidenced by netnames like INTRADO, INTRAFINITY-20, and BELL-9878800.
  • The AS announces 6912 IPv4 addresses across 13 prefixes and 7 IPv6 prefixes, maintaining 6 observed neighbours, a ratio consistent with an internal corporate estate rather than a transit or access network.

Notable

  • Registrants for the majority of prefixes are Intrado Life & Safety, Inc., while 199.84.136.0/23 is registered to Positron Industries Inc. and 208.71.176.0/23 to ConneXon Telecom, indicating acquired or leased space.
  • The inventory includes legacy netnames such as INTRAFINITY-20 and POSITRON-QC-CA, reflecting the company's history of mergers and acquisitions in the communications sector.
  • The address inventory is finely subdivided into multiple /23 and /24 blocks, typical of site-by-site segmentation for a large enterprise.

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: 453 networks and 1,854 prefixes, as published 2026-11-06. 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.
