Fellow Networkers, I have a question regarding current filtering rules/practices on the Internet and prefix length requirements for Class B space. I know that the ARIN space (64/8, 66/8 etc.) must be accepted at /19 or smaller but what about old class Bs? I have a global organization that has a 152.x.x.x /16. I currently I have 2 /19s out of POPs in the US and the aggregate /16 being advertised. I would like to give some of these /19s to other regions such as Europe, Japan, India, ASIA etc. The carrier selection in these regions will be different than what I have in the US. I want to know if anyone is filtering /19s for these networks. Any other information that I should be aware of in this scenario would also be very much appreciated. Thanks in advance.
