About this network

Netnames that are literally the address range written out, and two Dutch companies holding blocks inside a Mexican cable network.

What it's used for

• A cable operator's network. 57,088 addresses across 36 IPv4 prefixes plus one IPv6 prefix, 2806:240::/32, with 23 observed BGP neighbours.

Notable

• Several netnames are the range itself, such as 201.149.64.0 - 201.149.95.255 and 131.161.56.0 - 131.161.59.255, registered to Megacable Comunicaciones de Mexico, S.A. de C.V.
• 45.65.92.0/22 carries NL-LEGACO-20181113, registered to Legaco Networks B.V.
• 45.144.188.0/22 carries NL-PANQ-20190823, registered to Panq B.V.
• Six of eighteen sampled addresses returned a name, all of the form service-static-149.23.254.mcm-telecom.com.mx.

Interesting

• A netname that repeats the range is a registry declining to name anything. The field is required, so the software fills it with the only fact it already has, and the record ends up saying the block is the block.
• The two Dutch entries are dated in the name and prefixed with a country code, which is the European registry's convention. Space registered in one region and announced from another is routine now: addresses are traded, and the registry that issued them keeps the paperwork.
• The reverse names drop the first octet and keep the rest, so the hostname is not quite the address. They also carry a brand that is not the holder's, which is what happens when an operator buys another and keeps its zone.
