About this network

Some reverse names carry a transit provider's brand inside the label, on addresses this ISP registered itself.

What it's used for

• A regional ISP's network. 15,360 addresses across eight IPv4 prefixes plus one IPv6 prefix, 2607:6900::/32, with two observed BGP neighbours.

Notable

• All eight blocks come from 65.19, all carry the netname CYBERMESA-COM, and all list a Cyber Mesa Network Operations Center contact.
• Nine of eighteen sampled addresses returned a name, in several forms: dynamic-qwest-65-19-55-254.cybermesa.com, static-qwest-65-19-10-128.cybermesa.com, 65-19-6-128.wifi.cybermesa.com, tosc-wifi.cybermesa.com and ms1.tristate.cybermesa.com.

Interesting

• Naming a wholesale supplier in the customer-facing hostname is unusual and useful. Support staff can tell which upstream circuit an address rides without opening a ticket system, and the label records a commercial relationship that outlived the supplier's own name.
• The same zone holds generated labels, service labels and customer labels. A wireless access point, a mail server and a plain address all answer from one domain, which is what happens when an ISP small enough to know every customer names things by hand where it matters.
• Eight announcements out of one range, none of them adjacent, is a network that carved its allocation into pieces for internal reasons and advertises each separately.
• Two neighbours on 15,360 addresses, and one of the two is visible in the reverse names. There is very little hidden about how this network reaches the internet.
