AS15570 — INAP-LON Internap European Autonomous System

AS15570 announces 27 IPv4 prefixes covering 17,920 addresses and 1 IPv6 prefixes.

About this network

One reverse name has the whole zone suffix stuck on the end, from a missing full stop.

What it's used for

• A network and connectivity provider. Twenty-seven IPv4 prefixes and one IPv6 /34 announced from the United Kingdom, seventeen thousand addresses, across eleven observed BGP neighbours.

Notable

• One answering address returns a name that ends with the reverse zone's own suffix appended after the domain, which is what happens when a record is written without its trailing full stop and the zone origin is added automatically.
• A second address uses the same scheme without the fault, labelling itself as a broadcast address with a four-character site code.
• A third names a router under a fourth company's domain entirely.
• The AS handle and most netnames carry two retired brands, neither of them the current holder's name.
• One block is registered to a third brand and one lists only an abuse contact.
• Eighteen addresses were queried for reverse DNS and three returned a name.

Interesting

• The doubled suffix is the most common mistake in DNS zone files and one of the least noticed, because the record still resolves. It just resolves to a name nobody meant to write.
• Four brand names across the registry and reverse records trace a business sold at least twice, with each layer of naming left where it was.
• Twenty-seven routes for seventeen thousand addresses, most of them /23 and /24 blocks, is a transit network built from whatever space each acquisition brought with it.
