Hi,
just curious. Do you support the RIPE object called "assignment-size"
automatically?
https://apps.db.ripe.net/search/lookup.html?source=ripe&key=2001%3A980%3A3000%3A%3A/36&type=inet6num
for instance, indicates that each customer in this /36 is a /48. Do you
pick this up automatically and hint your abuse system about this? Does it
send automatically generated abuse reports to the abuse contact as well?
