Summary

Masonic Charity Foundation of New Jersey

United States · AI-generated

business enterprise

Three ways of writing one organisation's name, in three fields of the same record.

What it's used for

  • A charitable foundation's network. 256 addresses in a single IPv4 prefix, one observed BGP neighbour, and no IPv6 announced.

Notable

  • The block is 198.163.95.0/24, registered to MASONIC CHARITY FOUNDATION OF NEW JERSEY in capitals.
  • Its netname is MCFNJ, the initials of that name.
  • The AS handle is AS-MH001, a two-letter code with a zero-padded counter.
  • Three addresses were queried for reverse DNS and none returned a name.

Interesting

  • The handle is padded to three digits, which is a promise of up to a thousand of something. One number was ever issued, so the padding describes an expectation rather than an inventory, and it costs nothing to have been wrong.
  • Initials as a netname work while somebody remembers what they stand for. Five letters compress a seven-word name to the point where the record is findable only by the address it covers.
  • A foundation holding its own AS number and its own block is unusual at this size. It is what remains when an organisation was given space early and kept it through every change of provider since.

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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
