AS15533 — SASEUROPE
Network type: hosting
AS15533 announces 18 IPv4 prefixes covering 51,968 addresses and 1 IPv6 prefixes.
About this network
The one address that answers is a payment gateway host, named with a single blunt word.
What it's used for
- A managed services and hosting provider. Eighteen IPv4 prefixes and one IPv6 /31 announced from the United Kingdom, fifty-one thousand addresses, across four observed BGP neighbours.
Notable
- The single answering address returns a one-word host name under a domain about payment gateways, neither of which belongs to the provider.
- One block is registered to a financial data company and one to a news and information company, so customer identities sit in the registry as well as in DNS.
- That second customer block's netname is built from the prefix octets with a trailing index rather than from any name.
- Fifteen blocks share a netname stem with allocation dates spread across twelve years, the oldest and newest a decade and more apart.
- Eighteen addresses were queried for reverse DNS and one returned a name.
Interesting
- A payments host reachable by a memorable name is the finding worth acting on. Naming it at all narrows an attacker's search from fifty thousand addresses to one.
- An IPv6 /31 is unusually large, larger than most national carriers hold, and it sits against eighteen fragmented IPv4 routes.
- Two named customers in the registrant fields is what a managed hosting business looks like from outside: the addresses are the provider's, the names are whoever pays for them.
