AS15465 — SIEMENSDE peering with providers in
AS15465 announces 8 IPv4 prefixes covering 4,864 addresses and 2 IPv6 prefixes.
About this network
A netname with underscores, and a registrant that contains the words trading as.
What it's used for
- An industrial conglomerate's network. Eight IPv4 prefixes and two IPv6 /48 prefixes announced from Germany, nearly five thousand addresses, through two observed BGP neighbours.
Notable
- Five blocks use a netname of country code, company and allocation date, with dates from the early and mid-nineties, four of them identical.
- One netname is a subsidiary's full name with underscores between the words and ordinary capitalisation, both unusual for this field.
- That subsidiary's registrant runs to a dozen words, naming one company trading as another, with two different corporate forms and an ampersand.
- Another block's netname names a town in a neighbouring country, and a third is a four part code ending in an abbreviation for a group of continents.
- Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- Five thousand addresses is a small public footprint for a company of this size, and that is the point: an industrial group's networks are mostly not on the internet at all.
- The trading as clause is a legal restructuring written into a technical database. Somebody had to decide which name belonged in a field with no space for two.
- Allocation dates from the early nineties mark this as address space from before the registry system took its current shape, held continuously ever since.
