AS15547 — NETPLUS

Network type: residential

AS15547 announces 37 IPv4 prefixes covering 133,376 addresses and 3 IPv6 prefixes.

About this network

One thousand four hundred observed neighbours, which is a different order of magnitude from everything around it.

What it's used for

• A cable and broadband operator. Thirty-seven IPv4 prefixes and three IPv6 prefixes announced from Switzerland, a hundred and thirty-three thousand addresses, across more than a thousand four hundred observed BGP neighbours.

Notable

• The neighbour count is orders of magnitude above what a network of this size normally shows, and above most national carriers.
• Almost every netname carries a retired brand with an allocation date; the dates run across more than a decade with several blocks a year in the busiest stretches.
• One block breaks the pattern entirely with a different retired brand of its own.
• The single answering address reverses its octets and then adds a label spelling out the word reverse before the domain.
• Eighteen addresses were queried for reverse DNS and one returned a name.

Interesting

• A count this high usually means the number sits behind a federation of smaller networks rather than a single operator, so what looks like one company's neighbours is really many companies' worth.
• Thirty-seven routes with dates spread over a decade is a network that grew by absorbing allocations rather than planning them, which fits a cable operator consolidating regional franchises.
• Spelling out the word reverse in a reverse record is the same redundancy seen elsewhere in this range, and it survives for the same reason: a template wrote it and nothing objected.
