Summary

Lifeline Systems, Company

United States · AI-generated

enterprise legacy

LIFELINE-ASN is the network of Lifeline Systems, Company of Marlborough, Massachusetts — the medical alert service (the personal emergency response pendants and monitored help buttons) marketed simply as Lifeline.

What it's used for

  • Lifeline's own corporate and service infrastructure, announced from a contiguous set of prefixes in 199.36.96.0/22.
  • Backing an always-on monitored service: subscriber devices, the 24/7 response centres that answer them, and the business systems behind both.

Notable

  • An enterprise ASN in a fairly unusual line of work: this is life-safety monitoring, so the network exists to keep an alerting path continuously available rather than to move bulk traffic.
  • The company has changed hands over the years (it spent a long stretch as Philips Lifeline), but the ARIN organisation record has carried the Lifeline Systems name since the late 1990s.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
