Hosting ARIN
Summary
Serverel
hosting business infrastructure
Four different reverse naming conventions inside a single domain.
What it's used for
- A hosting provider. Eight IPv4 prefixes and one IPv6
/32announced from the United States, across four observed BGP neighbours.
Notable
- Seventeen of eighteen sampled addresses answered, and they use at least four formats.
- Some write the full address forwards before the domain, some write it backwards, some give only the last two octets, and two answer under a different domain entirely, marked as dynamic with the octets reversed.
- Two addresses in the same block can disagree: one gives all four octets and its neighbour gives two.
- All eight blocks carry the same netname, the company name with the protocol version and the word net, so the registry is entirely consistent while the DNS is not.
- Eighteen addresses were queried for reverse DNS and seventeen returned a name.
Interesting
- Four conventions in one zone is the signature of a zone assembled over years by different people and different scripts, each generating names for the block in front of it.
- The practical cost falls on anyone reading logs. A name here cannot be parsed by one rule, and the two octet form is ambiguous without knowing which block it came from.
- The second domain marking addresses as dynamic sits inside space registered to the hosting company, so some of this range is sold as consumer broadband under another brand.

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 2026-10-11, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
