Network type: hosting

AS14586 announces 14 IPv4 prefixes covering 3,840 addresses and 1 IPv6 prefixes.

About this network

Every sampled address answered, and the hostnames say whether the machine is physical, virtual, or a broadcast address.

What it's used for

• A server hosting provider. 3,840 addresses across 14 IPv4 prefixes plus 2605:6ac0::/36 of IPv6, with four observed BGP neighbours.

Notable

• The netnames run NFOSERVERS-CHI-1 through NFOSERVERS-CHI-14, with NFOSERVERS-DAL-7 sitting inside the sequence under a different site code.
• All eighteen sampled addresses returned a name.
• Hostnames come in two forms: c-74-91-124-128.premium-chicago.nfoservers.com and v-74-91-113-127.unman-vds.premium-chicago.nfoservers.com.
• One address is named broadcast.premium-chicago.nfoservers.com; two others return customer domains, including one under a privately run pseudo-suffix.

Interesting

• The single leading letter is the whole product catalogue. One marks a physical machine, the other a virtual one, and the virtual ones sit under a label announcing that nobody is administering them for you. A customer can read what they are paying for out of their own hostname.
• Numbering the second city's block seven in the middle of the first city's run means the counter is per company, not per city. The site code was added later, once there was a second site to distinguish.
• Naming the broadcast address is unusual and useful. Every block reserves its last address, and labelling it explicitly stops anyone from wondering why it never answers.
• Fourteen blocks totalling less than four thousand addresses is what growth looks like after address space ran out: a /24 at a time, from wherever it can be bought.
