  resolves: false
  note: NXDOMAIN as of 2026-09-04. Not a Seaboard Corporation domain; the catalog Website pointer that named it
    has been corrected to seaboardcorp.com.
note: Seaboard Corporation operates its subsidiaries on separate registrable domains. The corporate domain is seaboardcorp.com;
  www.seaboard.com (previously carried as the Website pointer) does not resolve at all. Subsidiary hosts are probed
  here because they are where any integration surface would live.
