Summary

Two blocks share a netname that is a provider's name and a single letter.
What it's used for
- An energy trading software company's network. Four IPv4 prefixes announced from the United States, no IPv6, and four observed BGP neighbours.
Notable
- Two of the four blocks are registered to a transit provider under one netname: the provider's name followed by a single letter, with nothing to distinguish the two assignments from each other.
- One block is registered to the company itself, with a netname that appends the block's address to the company name and a registrant that adds an operations centre after a semicolon.
- One block's registry lookup failed, so nothing can be said about who holds it.
- Twelve addresses were queried for reverse DNS and none returned a name.
- Two thousand addresses across four announcements and four upstreams.
Interesting
- A netname of a provider's name plus one letter is the least specific label that still parses. It says which provider and nothing else, and it appears on blocks in different ranges, so it cannot be used to tell assignments apart.
- Half the space here belongs to the provider and half to the company, which is what a network looks like partway through moving to its own address space. The provider's blocks go back when the contract does.
- Four upstreams for two thousand addresses is a company that treats connectivity as the product's dependency rather than an office utility, which fits software that sits between energy markets.

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 2026-10-21, 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: 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.
