Summary

Premera Blue Cross

United States of America · AI-generated

healthcare business corporate

PBC-WA is operated by Premera Blue Cross.

What it's used for

  • The space carries corporate infrastructure for a health insurance provider, evidenced by the netname PBC-199-187-64 and registrant Premera Blue Cross.
  • The AS announces 512 IPv4 addresses within a single prefix (199.187.90.0/23) and maintains 3 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.

Notable

  • The RDAP registrant Premera Blue Cross matches the registry holder and AS handle, confirming consistent ownership.
  • The address inventory consists of a single contiguous /23 block, typical of a corporate estate segmented for internal use.

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 1,779 prefixes, as published 2026-10-24. 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.
