About this network

Two addresses out of eighteen answer, and one of them answers with a customer's own company name.

What it's used for

• A legacy transit network. 146,944 addresses across 25 IPv4 prefixes, with 30 observed BGP neighbours and no IPv6 announced.

Notable

• The AS handle is UUNET-SA, the netnames are UUNET-BR1 and UUNET-BR2, and the registrant is Verizon.
• Twenty-three of the 25 prefixes fall inside 64.116 and 64.117, in every size from /17 down to /24.
• 200.58.0.0/18 is the one block carrying UUNET-BR1.
• Two of eighteen sampled addresses returned a name: 21Cust254.tnt3.sju2.da.uu.net and unilever0.unilever.com.
• The registry lookups for 64.116.224.0/19 and 64.117.192.0/20 failed.

Interesting

• One address in this network answers under a completely different company's domain. That happens when a provider assigns space to a customer and delegates the reverse zone with it, so the customer names their own addresses. It is the clearest evidence available from outside that a block is in use by someone other than the holder.
• The other name reads as a dial-up era access server: a customer number, a terminal server number, and a site code, under the provider's own domain. Both records still resolve.
• Three different labels describe one network: SA in the handle, BR in the netnames, and every prefix attributed to the United States. The registry, the routing and the naming were each filled in by someone with a different idea of where this was.
