We recommend setting a max-prefix of 500 on all IPv4 peering sessions and 100 on all IPv6 peering sessions with AS39216. 

** To ensure optimal routing, we by default announce regional (in-continent) prefixes to peers with global backbone scopes. Consistent multi-region announcement of our full global route-set is possible upon request. 

** We welcome and encourage dual-stack peering at all peering locations.
