Summary

government legacy

MASSACHUSETTS is the network of the Commonwealth of Massachusetts, administered by the state's central IT organisation in Chelsea, Massachusetts.

What it's used for

  • Statewide government connectivity: executive-branch agencies, state services and the judiciary. The AS announces roughly 230,000 IPv4 addresses across a dozen-odd prefixes, including several legacy /16s.
  • The netnames are unusually descriptive for a government network and reveal the functions directly: MASSCOURTS for the judicial system and MASS-DR for disaster-recovery addressing.

Notable

  • A US state government running its own AS with six figures of address space is a substantial public-sector network, comparable in size to a mid-tier enterprise or a small ISP, and it consolidates many agencies behind one origin.
  • The ARIN organisation record dates to 1991 and the ASN to 1996, so this is a genuine early allocation rather than a reissued low number.

Interesting

  • Dedicating registry-visible address space to disaster recovery is a continuity-of-government artifact. Most enterprises do not label their DR estate in public whois.

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 1,784 prefixes, as published 2026-10-19. 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.
