AS15525 — MEO-EMPRESAS

AS15525 announces 26 IPv4 prefixes covering 155,136 addresses and 2 IPv6 prefixes.

About this network

The registrant field says which blocks are the business arm and which are residential.

What it's used for

• A national carrier's business division. Thirty-four IPv4 prefixes and two IPv6 prefixes announced from Portugal, a hundred and fifty-five thousand addresses, across twenty-seven observed BGP neighbours.

Notable

• Most registrant entries end in a word for business, but one ends in a word for residential, so a block belonging to the consumer side is announced by the business network's number.
• Netnames carry two retired brands rather than the current one, each with an allocation date, and one of those dates uses a two-digit year where the rest use four.
• One block is registered to an unrelated party entirely, with a short code in place of a company name.
• The holder's name is written in capitals with the accents stripped out, so several words are missing the marks they normally carry.
• Eighteen addresses were queried for reverse DNS and two returned a name, both under a domain unrelated to the operator.

Interesting

• Business and residential arms sharing one AS number while keeping separate registrant labels is how a carrier splits its commercial reporting without splitting its routing.
• Thirty-four routes covering blocks from a /17 down to a /24 is what a national network looks like after two decades of acquiring space in whatever sizes were available.
• Two retired brands still naming the address space is the most durable kind of corporate history. The marketing changed twice and the registry did not.
