Summary
Angelo Gordon
finance business enterprise
Reverse DNS labels every address user plus its last octet, published on an investment firm's own domain.
What it's used for
- An investment management firm's network. 512 addresses across two IPv4 prefixes,
63.71.3.0/24and64.74.248.0/24, two observed BGP neighbours, and no IPv6 announced.
Notable
63.71.3.0/24is netnameUU-63-71-3, registered to the firm under a carrier's initials.64.74.248.0/24is netnameINAP-NYM-TELCODIGITAL-2337, registered to a different company.- Three sampled addresses answered as
user64,user127anduser190under the firm's domain. - The firm's name appears three ways across the AS object, the address object and the domain, with different punctuation each time.
Interesting
- Naming addresses
userplus a number is the opposite of a host inventory. It says these are people rather than servers, which is more than an outsider needs to know, and it makes counting the desks behind the block a matter of probing. - The second netname packs a carrier's initials, a metro market code, the customer name and a four-digit ticket number into one field. That last number is an order reference that escaped into a public registry and stayed there.
- Announcing a block registered to another company usually means that company is a provider, a subsidiary or a tenant. The registry does not say which, and the routing table does not care.

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 2026-11-13, 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: 455 networks and 1,849 prefixes, as published 2026-11-13. 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.
