AS13999 — Mega Cable, S.A. de C.V.

AS13999 announces 600 IPv4 prefixes covering 1,952,512 addresses and 273 IPv6 prefixes.

About this network

Nearly two million addresses whose reverse names announce which city each customer is in and whether they share an address.

What it's used for

• A national cable broadband network. 1,970,176 addresses across 962 IPv4 prefixes plus 327 IPv6 prefixes, all announced from Mexico.

Notable

• The largest blocks are 177.226.0.0/16, 187.240.0.0/16 and 187.242.0.0/16.
• Netnames are the address ranges themselves, in the form 177.224.0.0 - 177.231.255.255.
• Every sampled address returned a name. They take the form customer-GDL-PUBLIC-CGN-32-0.megared.net.mx, with a three or four letter city code, an optional PUBLIC, and the last two octets.
• The routing status lookup failed, so neighbour count and first-seen date are unknown.
• The registry lookup for 177.224.192.0/18 failed.

Interesting

• CGN marks addresses shared between many subscribers rather than assigned to one. Publishing that in reverse DNS tells anyone querying an address whether it identifies a household or a few hundred of them, which matters enormously to anyone trying to act on an address.
• The word PUBLIC appears alongside CGN on some names and not others, so the same naming scheme distinguishes shared space from dedicated space within one city. That distinction is usually invisible from outside a provider.
• The netnames are the first and last address of each range. Where other registries take a short label, this one records the boundaries, which makes the field useless as an identifier and perfect as a description.
• Eighteen sampled addresses gave eleven different city codes. A provider that labels every address with its location has built its reverse DNS from the same inventory that tracks where the equipment physically is.
