About this network

Every netname says legacy, every reverse name starts with a state code, and three different domains serve one small network.

What it's used for

• A regional slice of a national carrier's broadband network. 22,272 addresses across 18 IPv4 prefixes, with a single observed BGP neighbour and no IPv6 announced.

Notable

• The AS handle is CENTURYLINK-LEGACY-EMBARQ-VACHVL, and every block that resolved carries a netname of the form CENTURYLINK-LEGACY-EMBARQ-BKL-10, numbered 2, 6, 7, 10 and 14.
• All twelve resolved registrations read CenturyLink Communications, LLC with no variation.
• All eighteen sampled addresses returned a name, across three domains: va-76-4-84-0.dhcp.embarqhsd.net, va-184-2-132-0.sta.centurylinkservices.net and 184-2-139-254.dia.static.centurylink.net.
• The labels distinguish dhcp, dyn, sta, dia and static as separate categories.

Interesting

• Carving one AS number per legacy region and naming it after the acquired company is how a carrier absorbs a purchase without renumbering anything. The handle ends in a place code, so the AS is a geographic shard.
• The state abbreviation on the front of nearly every label is provisioning metadata that will outlive its accuracy. Addresses get reassigned; the two-letter prefix does not follow.
• Five words for two ideas. Whether a line is dynamic or fixed is expressed as dhcp, dyn, sta, static or dia depending on which era and which platform turned it up, and all five answer from the same estate.
• One neighbour is what an internal shard looks like from outside: it reaches the world through the carrier's own backbone and nowhere else.
