About this network

SKYWOLF-AS-AP is Skywolf Technology LLC, trading as Skywolf Cloud — a small cloud and VPS provider. The company is registered in Sacramento, California, but its network is run out of leased datacentre space in Santa Clara and Hong Kong.

What it's used for

• VPS and cloud hosting. Its APNIC block is registered with the netname SKYWOLF-CLOUD in Hong Kong; its ARIN /24 is registered as SKYWOLF-BACKBONE. Both are in the company's own name, and it publishes a looking glass and BGP community documentation.
• Small-scale transit. Despite holding under a thousand IPv4 addresses of its own, it has upstreams from a tier-1 carrier and appears as the upstream for several dozen small downstream networks — the low-cost BGP transit that hobbyist and micro-ASNs buy to get their prefixes routed.
• IPv6 is where most of the network lives: it announces considerably more IPv6 prefixes than IPv4, drawn from both ARIN and APNIC ranges.

Notable

• PeeringDB types this network as "Cable/DSL/ISP". The inventory does not support that. There are no subscriber pools, no consumer-style reverse DNS, and no eyeball footprint anywhere in the space. It is a hosting and transit operation. Where a self-description and the announced prefixes disagree, the prefixes are the honest witness.
• Its prefixes span two RIRs, but unlike an address-brokering shape they are registered to Skywolf itself, not to unrelated third parties — so this is a genuine, if small, operator.
• Do not read the low AS number as early-internet pedigree. Skywolf is a recently built commercial network; the number long predates the company.

Interesting

• The IPv4 footprint is tiny while the customer cone is not. That inversion — a few hundred addresses, dozens of downstreams — is characteristic of the modern "cheap transit for small ASNs" niche, where the product is routing, not addresses.
