enterprise business infrastructure

A netname in a format the registry stopped issuing decades ago.

What it's used for

  • A hospital system's network. 1,024 addresses in a single IPv4 prefix, with two observed BGP neighbours and no IPv6 announced.

Notable

  • The entire footprint is 198.72.0.0/22, carrying the netname NETBLK-NMMC.
  • The four letters after the prefix do not match the initials of the organisation on the same record.
  • Three addresses were queried for reverse DNS and none returned a name.
  • The AS first appeared in routing on 2001-01-18.

Interesting

  • The prefix on that netname marks an era. Records created when address space was still handed out by a single central authority carried it as a matter of course, and it survives only on blocks nobody has had cause to refile. Finding one is a reliable way to date a record without a date field.
  • The initials belong to a slightly different name than the one on the record, which is the ordinary fate of a hospital that has merged, rebranded or dropped a word. Nobody updates a netname for a change of letterhead.
  • A health system publishing nothing in reverse DNS is behaving correctly. Patient portals and clinical systems have no reason to be findable by scanning address space, and everything patients touch is reached through names held elsewhere.
  • One block and two upstreams is a small and unremarkable public footprint for an organisation of this size, with the interesting traffic staying on private links.

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 1,852 prefixes, as published 2026-10-27. 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.
