Summary

hosting isp
A small network with 14 neighbours, two IPv6 /32s, and a /23 the registry still lists as its own.
What it's used for
- Hosting and connectivity. 768 addresses in two IPv4 prefixes, two IPv6
/32s, and 14 observed BGP neighbours.
Notable
23.161.32.0/24is netnameVC-DEN-V4-01, registered to Vertical Computers.23.187.0.0/23looks up as netnameNET23, registrantAmerican Registry for Internet Numbers— the registry's own parent record rather than an assignment.- Two IPv6
/32s from different ranges,2604:d2c0::/32and2620:1df::/32. - 14 neighbours against 768 addresses.
Interesting
- When a lookup returns the registry as the registrant, what it usually means is that no more-specific record covers that block, so the query falls through to the
/8the registry holds for itself. The prefix is announced and routed either way; it is the paperwork underneath that has a gap in it. 2620::/23is the range reserved for direct assignments to end-user organisations rather than to providers, so holding a/32from it alongside one from ordinary provider space means the two were obtained by different routes, years apart.DENin the netname is Denver, andV4distinguishes it from the address family the company clearly expected to be labelling next.

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: 442 networks and 1,778 prefixes, as published 2026-10-20. 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.
