 Tips
Cyclops detects cases where prefixes are announced out of the normal lenghts, i.e. shorter than /8 and longer than /24 for v4 and shorter than /32 and longer than /64 for v6, excluding cases where prefixes are explicited listed by IANA or RIRs. If you are ASN X announcing any of these prefixes, Cyclops will generate an anomaly that you can lookup querying for ASN X.
