business insurance corporate internal

WELLMARK is the autonomous system for Wellmark Blue Cross and Blue Shield.

What it's used for

  • The address space is registered under the netname NETBLK-IABLUESNET for the registrant WELLMARK BLUE CROSS AND BLUE SHIELD.
  • The AS announces 2560 IPv4 addresses across 2 prefixes and maintains 2 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate communications, web services, and API endpoints for the health insurance company's operations in Iowa and South Dakota.

Notable

  • The RDAP registrants for both announced prefixes match the AS holder, confirming consistent ownership of the address space.
  • Wellmark Blue Cross and Blue Shield is a mutual insurance company serving over two million members in Iowa and South Dakota, operating as a single-state member of the Blue Cross Blue Shield Association.
  • The inventory consists of two contiguous IPv4 blocks: 198.245.32.0/21 and 198.245.40.0/23, with no IPv6 prefixes announced.

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 1,771 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.
