AS10685 ASA5COM

ASA5COM belongs to A5.COM, LLC, a small IT infrastructure and data center company based in Peoria, Illinois. It is a compact network: RIS observes 6 announced IPv4 prefixes totalling around 12,288 addresses, no IPv6, and just 4 BGP neighbours.

What it's used for

A5.COM sells colocation, dedicated and cloud servers, storage, and managed services out of regional Illinois data centers, alongside IP connectivity for business customers. The routing evidence is consistent with that: the AS anchors two aggregates (209.251.96.0/19 and 216.201.112.0/20) and then deaggregates a handful of /24s out of them, which is what a provider does when it needs to steer individual customer or service blocks. Sampled reverse DNS resolves to first-party names — cache2.a5.com and cdns.a5.com — confirming the company both holds and operates the space rather than reselling it under someone else's naming.

Notable

Four observed neighbours is the profile of a multi-homed regional provider buying transit from a few upstreams, not a carrier selling it. Combined with an address count in the low five figures, this is a service-provider network at metropolitan scale: enough space to host customer infrastructure, nowhere near enough to be an eyeball ISP of consequence.

Interesting

The company traces its IP networking work to the mid-1990s, which is consistent with holding a low-numbered ASN and legacy-era 209.x and 216.x space from the pre-2000 allocation era.
