Unclassified ARIN
Summary
NYCPM
business enterprise
Five letters, repeated in every field the registry offers.
What it's used for
- An institutional network. 256 addresses in a single IPv4 prefix, one observed BGP neighbour, and no IPv6 announced.
Notable
- The block is
207.90.250.0/24, netnameNYCPM, registered toNYCPM. - The AS handle is also
NYCPM. - Routing was first seen in 2000.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- The holder name, the handle, the netname and the registrant are the same five characters. That is rare. Most records disagree with each other somewhere, because they are filled in by different people at different times, and total agreement means one person filed everything at once.
- What the letters expand to is not in any of those fields. An acronym that never appears alongside its expansion is only legible to people who already know the organisation, which was a perfectly reasonable assumption when internet registries were mostly read by the institutions in them.
- A single
/24behind one upstream, unchanged since 2000, is a network that has needed nothing since it was set up. Continuity like that is invisible from the outside precisely because nothing about it ever changes.

Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-25, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 2026-10-24. 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.
