AS15969 — SYSTEMIA-AS

AS15969 announces 5 IPv4 prefixes covering 5,632 addresses and 2 IPv6 prefixes.

About this network

Two separate provider-sized IPv6 allocations from different ranges, on a network of five thousand IPv4 addresses.

What it's used for

• A hosting and connectivity company. Five IPv4 prefixes and two IPv6 /29s announced from Poland, five thousand six hundred and thirty-two addresses, across six observed BGP neighbours.

Notable

• Both IPv6 prefixes are /29s, the size given to a provider to hand out, and they come from ranges that are nowhere near each other.
• Three netnames follow a country code, the brand and a date, spanning eight years.
• The other two blocks belong to different companies: one a network business with its own operations contact, the other registered to a private individual trading under a brand.
• Six of fifteen queried addresses answered. Six are the third and fourth octets hyphenated, then a two-letter label for an address, then the brand's domain.
• The seventh sits on the block held by the other company and uses a fourth party's domain entirely, with a three-letter prefix before the octets.

Interesting

• Holding two provider allocations rather than one usually means the second was inherited with a business rather than requested. Registries hand out one and expand it; two disconnected ones is the signature of a merger.
• Keeping only the last two octets in a reverse name works because the zone already fixes the first two. It costs nothing until somebody pastes a name into a ticket without the block it came from.
