Unclassified RIPE
Summary
ASPA-INVALID (Antonios A. Chariton)
research legacy
A small personal network run by Antonios A. Chariton, transferred into the RIPE
region in 2024 and deliberately configured to be RPKI ASPA Invalid. The
RIPE object is literally named ASPA-INVALID.
What it's used for
- A live routing-security experiment. Its ASPA object declares that only AS0 may be its upstream, while in reality it is announced behind a real transit AS — so any validating network should reject its routes.
- Announcing a single IPv4 /24 (
193.5.19.0/24) and one IPv6 /48.
Notable
- Not an eyeball or hosting network. AS4492 exists to be wrong on purpose, as a measurable canary for ASPA deployment.
- The stated expectation is that as ASPA validation spreads, the visibility of this AS's prefixes should fall toward zero — making it a slow-moving, real-world adoption gauge.
Interesting
- The low AS number is not early-internet pedigree. This one was reissued and moved between registries in 2024; the current holder is a modern operator who put it to a very unusual use.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
No IC3 indicators Nothing from the FBI IC3 feed.
Threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
