AS14653 announces 5 IPv4 prefixes covering 3,328 addresses and 0 IPv6 prefixes.

About this network

Half its published names are addresses written backwards; the other half are numbered telephone systems.

What it's used for

• A voice and connectivity provider's network. 3,328 addresses across five IPv4 prefixes, with two observed BGP neighbours and no IPv6 announced.

Notable

• The blocks split into two groups by netname, P360-1 and P360-2, each covering a different part of the address space.
• Eleven of fifteen sampled addresses answered, in two forms: 255-213-21-199.pulsar360.com and pbx1491.pbx.pulsar360.com.
• The AS carries a first-seen timestamp of 2000-08-18T08:00:00, the start of the routing archive.

Interesting

• The first form is the address with its parts in reverse order, generated automatically for everything with no better name. The second is assigned by hand to a hosted telephone system, one per customer, each with its own four-digit number. You can read the company's product line directly out of its reverse zone: unremarkable connectivity, and phone systems it runs on the customer's behalf.
• Those system numbers run into the thousands and are not sequential across the sample, so the counter is global and has been running a long time. Numbering customers rather than naming them is what you do when there are too many to remember.
• Both netnames are the brand shortened to four characters and a number, which is the tidiest scheme in this part of the range and still tells an outsider nothing.
• Voice traffic is why there are two upstreams and no IPv6: calls break visibly when a path fails, and nobody has ever demanded a phone system be reachable over the newer protocol.
