Summary

Lucile Packard Children's Hospital at Stanford

United States of America · AI-generated

hospital healthcare business us

LPCH-PA is operated by Lucile Packard Children's Hospital at Stanford.

What it's used for

  • The address space carries hospital infrastructure, with the primary netname LPCH-PALO registered to the hospital.
  • The AS announces 1280 IPv4 addresses across 2 prefixes and maintains 4 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal hospital systems, clinical data, and administrative endpoints for the pediatric and obstetric care facility in Palo Alto.

Notable

  • Registrants for the primary prefix 199.68.152.0/22 align with the announcer, while the secondary prefix 38.70.239.0/24 is registered to Cogent Communications, LLC.
  • The address inventory is finely subdivided into two distinct blocks, consistent with an internal corporate estate managing separate segments for different operational needs.

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: 454 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.
