AS15544 — DATAWAYS DATAWAYS S.A.

Network type: hosting

AS15544 announces 5 IPv4 prefixes covering 4,608 addresses and 3 IPv6 prefixes.

About this network

The single answering address is a core router, named down to the sub-interface.

What it's used for

• An internet and hosting provider. Six IPv4 prefixes and three IPv6 /36 prefixes announced from Greece, nearly five thousand addresses, across seventeen observed BGP neighbours.

Notable

• The one address that answered names a network layer, the word core, a gigabit interface number and a sub-interface number, all in one label.
• The three IPv6 prefixes are the same size and sit at evenly spaced offsets in one range, leaving a fourth slot of equal size unannounced.
• Five netnames carry the country code, the company and one of two allocation dates fifteen years apart; the sixth names an unrelated services brand.
• Seventeen addresses of eighteen returned nothing, so the only public name in this network belongs to its own infrastructure.
• Eighteen addresses were queried for reverse DNS and one returned a name.

Interesting

• Naming a core router with its interface and sub-interface numbers is useful to operators tracing a path and useful to anyone mapping where the network's spine sits. It is the one thing here that did not need to be public.
• Three evenly spaced IPv6 blocks with a gap at the fourth position looks like a plan for four sites where three were built.
• Seventeen neighbours for five thousand addresses is dense interconnection, and it is what a provider in a single national market buys instead of long-haul transit.
