Summary

Shore Memorial Hospital

United States · AI-generated

enterprise business infrastructure

The netname substitutes a different word for the one in the hospital's name.

What it's used for

  • A community hospital's network. 256 addresses in the single IPv4 prefix 198.22.136.0/24, three observed BGP neighbours, and no IPv6 announced.

Notable

  • The block is netname SHORE-MEDICAL while the registrant reads Shore Memorial Hospital.
  • The two words share their first three letters and nothing else.
  • The AS handle is SMH, initials taken from the registrant rather than from the netname.
  • First seen in the routing archive on 2006-03-28, timestamped in the afternoon rather than the usual morning.
  • Three addresses were queried for reverse DNS and none returned a name.

Interesting

  • Swapping one word for another that starts the same way is the kind of substitution that happens when a name is entered from memory rather than copied. The netname is not wrong about who holds the block, only about what they are called, and it stays that way because nothing checks.
  • Three upstreams for a single /24 is more redundancy than most organisations this size buy. For a hospital, where the network carries records and imaging between sites, the extra path is worth more than the address count suggests.
  • A single small block with three paths into it and nothing answering a reverse lookup is a network built to stay up and stay quiet.

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: 443 networks and 1,779 prefixes, as published 2026-10-25. 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.
