Proof of concept: py-radix's Radix.delete() silently removes unrelated
prefixes as a side effect of deleting a different prefix.

On a tree built purely with Radix.add() (no prior deletions), deleting a
batch of prefixes one at a time via Radix.delete(prefix) causes some
prefixes that were never passed to delete() to vanish from the tree too.
When the loop later reaches one of those now-vanished prefixes, delete()
correctly raises KeyError for it (it really is gone) - but it should never

# Example script which will get the number of IPv4 and IPv6 prefixes seen via each ASN in PeeringDB with a non-zero prefix limit.
# For example purposes; script is limited to the first 10 ASNs in PeeringDB, and one route collector, route-views.isc.
# Possible usage would be to query the broken API (https://status.broker.bgpkit.com/?tab=collectors) for a few route collectors
# which DON'T have this ASN connected, but DO have a few full table feeds each, to get a world view of that ASN.
# This script uses a locally built Monocle binary, the docker image can't be used until v1.4 is released:
