Summary

Westat

United States of America · AI-generated

business research corporate

WESTAT-AS1 is operated by Westat, Inc.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by reverse DNS entries such as trc-info.westat.com, meps-m3.westat.com, and nhatscaricodenatprd.westat.com.
  • The AS announces 2048 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, self-contained corporate network rather than a transit or access provider.

Notable

  • All registrants for the announced prefixes are listed as Westat, Inc. with the netname NETBLK-WESNET, fully consistent with the AS holder.
  • Westat is an employee-owned professional services corporation based in Bethesda, Maryland, providing research and data analysis services to government agencies and businesses.
  • The inventory consists of a single /22 block and three smaller /24 and /23 blocks, all under the same netname, reflecting a consolidated corporate estate.

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 1,782 prefixes, as published 2026-10-16. 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.
