AS13591 — Mexico Red de Telecomunicaciones, S. de R.L. de C.V.

AS13591 announces 149 IPv4 prefixes covering 492,440 addresses and 67 IPv6 prefixes.

About this network

Reverse names built from only the last octet, so the same hostname answers for addresses in different subnets.

What it's used for

• A telecommunications carrier. 492,440 addresses across 226 IPv4 prefixes, 102 IPv6 prefixes, and eight observed BGP neighbours.

Notable

• 170.25.0.0/16 is registered to a financial group, not to the carrier announcing it.
• The carrier's own netnames are the address range written out with a hyphen between its endpoints.
• 148.246.208.0, 148.246.72.0 and 148.246.136.0 all answer as customer-cc-0.static.metrored.net.mx.
• 177.232.208.0 answers as host-177-232-208-1, and 187.186.80.0 as customer-mred-1.
• Fourteen of eighteen sampled addresses answered.

Interesting

• A reverse name that encodes only the final octet is not unique. Three addresses in three different ranges return the identical string, so anything that treats a hostname as an identifier, including log analysis and access rules, will merge networks that have nothing to do with each other.
• Two addresses ending in zero answer with names ending in one. The generator counts from one while the subnet counts from zero, and the mismatch only shows at the boundary.
• A bank's /16 carried inside a carrier's announcements is ordinary wholesale: the financial group owns the space and buys the transit, and the routing table records the arrangement.
