AS14921 announces 31 IPv4 prefixes covering 61,440 addresses and 0 IPv6 prefixes.

About this network

Two addresses four apart in the same block claim to be in different states.

What it's used for

• A consumer broadband network inherited through a chain of acquisitions. 61,440 addresses across 31 IPv4 prefixes, with one observed BGP neighbour and no IPv6 announced.

Notable

• Every netname reads CENTURYLINK-LEGACY-EMBARQ-BKL- followed by a number, and several different numbers appear across the 31 prefixes.
• Every one of them is registered to CenturyLink Communications, LLC.
• All eighteen sampled addresses returned a name, every one under embarqhsd.net, in three zones: dyn, dhcp and sta.
• Two of them are fl-67-237-100-0.sta.embarqhsd.net and or-67-237-103-255.sta.embarqhsd.net.

Interesting

• Those two sit inside the same /20, and their names give different states. A block that small does not span a country, so at least one label is wrong. The state code is written when a range is provisioned and never checked again, so a reassigned block keeps whichever code it was born with.
• The netname says LEGACY out loud. A carrier that has absorbed several others keeps the old brand in the record precisely so its own engineers know which acquisition a block came from.
• Eighteen of eighteen addresses answering is unusual in this range. Consumer broadband names every line whether anything is listening or not, because the naming is generated from the provisioning system rather than from what exists.
• One neighbour holding 31 prefixes: this is a piece of a much larger carrier rather than a network in its own right.
