Summary
A5.COM, LLC
hosting enterprise legacy
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.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 443 networks and 1,784 prefixes, as published 2026-10-19. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
