About this network

The AS handle SK2 is held by Rackspace Germany GmbH.

What it's used for

• The address space carries Rackspace infrastructure, evidenced by the reverse DNS record dnscorea.nsmon.arn1.rackspace.net and the netname ARN1.
• The AS announces 1024 IPv4 addresses and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, self-contained hosting or internal corporate estate rather than a transit provider.
• Traffic from this AS consists of Rackspace's cloud and managed hosting services, specifically supporting DNS monitoring and core network operations for its German operations.

Notable

• The RDAP registrant for the announced prefix 166.86.196.0/22 is listed as RXT Sweden AB, which differs from the AS holder Rackspace Germany GmbH, suggesting the address space may be leased or historically allocated to a related entity.
• The inventory consists of a single /22 IPv4 block and a /32 IPv6 prefix, representing a compact and specific allocation for the operator's infrastructure.
