Summary
Layer 7 Consulting
business finance hosting
Half its address space is registered to its clients, and both of them are finance firms.
What it's used for
- A managed-services consultancy's network. 2,048 addresses across four IPv4 prefixes, with five observed BGP neighbours and no IPv6 announced.
Notable
208.91.152.0/22and208.86.116.0/23carry the netnameLAYER-7-NETWORKSand are registered to the consultancy.208.86.118.0/24is registered toMonroe Capitaland208.86.119.0/24toMBF Clearing Corp., each with its own netname.- Those two client blocks sit immediately after the consultancy's own in the same range.
- Twelve addresses were queried for reverse DNS and none returned a name.
Interesting
- The address plan is visible in the numbering: one allocation, the first half kept, the next two pieces handed to clients who then filed their own registry records. That last step is what makes this arrangement worth doing, because a client with its own record can take the addresses with it if the relationship ends.
- Both clients are in finance, which is the market that most often outsources the running of a network while refusing to give up the addresses. Trading firms hard-code addresses into counterparty configurations, and renumbering means renegotiating with everyone.
- Five neighbours for four blocks is a lot of connectivity for a small estate, and the right amount when the traffic on it is somebody else's order flow.
- Nothing published in reverse DNS, which for this clientele is the expected answer.

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 2026-10-19, 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 1,783 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.
