About this network

Reverse DNS labels every address user plus its last octet, published on an investment firm's own domain.

What it's used for

• An investment management firm's network. 512 addresses across two IPv4 prefixes, 63.71.3.0/24 and 64.74.248.0/24, two observed BGP neighbours, and no IPv6 announced.

Notable

• 63.71.3.0/24 is netname UU-63-71-3, registered to the firm under a carrier's initials.
• 64.74.248.0/24 is netname INAP-NYM-TELCODIGITAL-2337, registered to a different company.
• Three sampled addresses answered as user64, user127 and user190 under the firm's domain.
• The firm's name appears three ways across the AS object, the address object and the domain, with different punctuation each time.

Interesting

• Naming addresses user plus a number is the opposite of a host inventory. It says these are people rather than servers, which is more than an outsider needs to know, and it makes counting the desks behind the block a matter of probing.
• The second netname packs a carrier's initials, a metro market code, the customer name and a four-digit ticket number into one field. That last number is an order reference that escaped into a public registry and stayed there.
• Announcing a block registered to another company usually means that company is a provider, a subsidiary or a tenant. The registry does not say which, and the routing table does not care.
