About this network

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.
