Time to update those IP Bogon Filters (again)

Looks like the Internet Assigned Numbers Authority (IANA) has recently assigned two more IP prefixes to the American Registry for Internet Numbers (ARIN):

50.0.0.0/8  and  107.0.0.0/8

For those of you that maintain IP Bogon Filters, you may want to adjust your filters accordingly.

I'm really not keen on these Bogon filters. With the sole exception of the IP prefixes reserved for internal uses. But in a perfect world maybe everyone would be peered with networks that implement BCP38.
