AS14638 — LCPRL

AS14638 announces 56 IPv4 prefixes covering 333,824 addresses and 3 IPv6 prefixes.

About this network

Every address that answers gives the same name back, and the company's initials are transposed in one of its own netnames.

What it's used for

• A cable ISP. 333,312 addresses across 309 IPv4 prefixes plus 39 IPv6 prefixes, with nine observed BGP neighbours.

Notable

• Most blocks carry the netname LCPRL, but 24.42.0.0/19 carries LCRPL.
• Other netnames in use are SJCL-1, SJCL-2, CHOICE-CM10 and LIBERTYPR.
• 24.42.32.0/20 registers to Liberty Cablevision - Humacao rather than to the parent company.
• The registrant name itself is written two ways, with and without the word "of".
• Five of eighteen sampled addresses returned a name, and all five returned exactly dynamic.libertypr.net.
• The IPv6 announcement covers two /33s, 2604:b000::/33 and 2605:ba00::/33, plus smaller pieces of each.

Interesting

• LCRPL transposes two letters of LCPRL. Both records are live, both are authoritative for their own block, and nothing in the registry marks one as the typo. Netnames get typed once and read forever.
• Five different addresses answering with one identical name is a wildcard: a single record covering a whole zone, saying only that the address is dynamic. It is the least an operator can publish while still publishing something, and it defeats any attempt to tell one customer's address from another's by name.
• 309 prefixes for 333,312 addresses averages barely a thousand addresses each. A cable network assembled from hundreds of small acquisitions announces them the way it received them.
