Anomalies
   Transient Prefix Origins  Anomalous Depeerings  Bogus ASNs  Bogon Prefixes  Long/short Prefixes   
ASN or AS Name: multiple ASNs as e.g. 52,7018
Bogus ASN: multiple ASNs as e.g. 64512,0
Start date: *
End date: *

 Tips
Bogus ASNs are AS numbers that are not supposed to be advertised in BGP. Cyclops extracts the bogus ASN filter from IANA, and keeps track of all valid ASNs that appear connected to a bogus ASN. E.g. , you are X and Cyclops sees a path X-B or B-X where B is a bogus ASN, then it will generate an anomaly for X. You can query this anomaly by looking up for X in the ASN field.
