Summary

Vantive Health

United States of America · AI-generated

healthcare business corporate us

The AS handle VANTIVE-HEALTHCARE is held by Vantive Health.

What it's used for

  • The address space carries corporate infrastructure for a healthcare organization, as indicated by the consistent netname VANTIVE and registrant Vantive Health across all prefixes.
  • The AS announces 5376 IPv4 addresses across 9 prefixes with only 3 observed neighbours, a ratio that implies an internal corporate estate with site-by-site segmentation rather than a transit or access network.

Notable

  • All registrants agree with the announcer, consistently listing Vantive Health as the registrant for every prefix in the inventory.
  • Vantive is a late-stage company based in Redwood City, founded in 1990, operating as a vital organ therapy company.
  • The address inventory consists of nine contiguous blocks within the 159.198.128.0/18 range, subdivided into /22, /23, and /24 prefixes.

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: 442 networks and 1,772 prefixes, as published 2026-10-15. 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.
