Tips

When in Snapshot mode, you can check the complete list of prefixes announced by a given ASN. In Diff mode you only see the prefixes which appear or disappear between a window of time defined by start and end dates. You can further filter the results by specifying the geographical location and aggregate results by ASN, Country or City. Cyclops extracts the geographical location of prefix from Maxmind's GeoLite City.
