Customers of AS 6327 we have spoofer tests from

This is the list of directly connected customers of AS 6327 from which we have received a spoofer test, ordered by the customer's ability to send spoofed packets and the number of prefixes of an inferred ingress ACL derived from prefix announcements for the customer recorded in public BGP data. BCP-84 describes ingress ACLs as "the most bulletproof solution when done properly" and the "best fit ... when the configuration is not too dynamic, ... if the number of used prefixes is low." Further detail about the size and dynamism of an inferred ACL is available by following the History link for each AS.
