Hosting ARIN
Summary

hosting infrastructure business
This number announces no IPv4 at all, only a single IPv6 prefix.
What it's used for
- A colocation provider's network. No IPv4 prefixes and one IPv6 prefix announced from the United States, through one observed BGP neighbour. The inventory holds no IPv4 blocks whatsoever.
Notable
- The AS handle joins two company names with a hyphen: a parent brand and a second brand written as a lower-case letter in front of the word for colocation.
- The holder line gives only the second of those two names, so the handle preserves a history the holder field has already dropped.
- With no IPv4 blocks in inventory there were no addresses to sample, and the reverse DNS section is empty for want of anything to ask.
- One observed neighbour carries the whole announcement.
Interesting
- An AS number that carries only IPv6 is almost always transitional: either the address space moved to another number in the same group and the newer protocol was left behind, or a prefix was put into service ahead of its counterpart.
- Two company names in the handle where the holder gives one is the cheapest possible record of an acquisition. Nobody rewrote the handle, and the handle is the part that remembers.
- A single upstream on a colocation provider's number means this is not the routing identity the business runs on.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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 1,779 prefixes, as published 2026-10-22. 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.
