AS16466 AVAYA-ONECLOUD

Nine blocks, nine identical netnames, and the netname describes a parent block that is never announced.

What it's used for

• A communications vendor's network. Nine IPv4 prefixes announced from the United States, no IPv6, four thousand six hundred and eight addresses, through five observed BGP neighbours.

Notable

• Every announced block is the same size, and every one is registered to the same company under exactly the same netname.
• That netname is the brand, then the first two parts of the parent range, then two zeroes standing in for the parts that vary, then a single trailing letter. It names a range that is not itself announced.
• The trailing letter implies a sibling somewhere with a different letter, and nothing in this record shows one.
• The blocks are scattered through the parent range rather than contiguous, so the company holds pieces of a much larger allocation and routes only some of them here.
• The AS handle is the brand and a product name run together, which makes it the only field that says what the network is for.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• One netname across nine registrations means the registry entries were generated from a template, not written. The field stops being a name and becomes a category.
• A vendor that sells communications platforms to other companies keeps its own service addresses quiet. Five upstreams and no reverse names is a network built for reachability rather than for identification.
