AS14721 — LAYER-7-NETWORKS

AS14721 announces 2 IPv4 prefixes covering 2,048 addresses and 0 IPv6 prefixes.

About this network

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

• 208.91.152.0/22 and 208.86.116.0/23 carry the netname LAYER-7-NETWORKS and are registered to the consultancy.
• 208.86.118.0/24 is registered to Monroe Capital and 208.86.119.0/24 to MBF 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.
