I went to http://www.iana.org/assignments/ipv4-address-space and grep-ed
for APNIC (Asia-Pacific Network Information Center) to get the following
list. For the church email site that I support I block wholesale /8 IP
address ranges. I assume that for our church we will never get email
from an APNIC site.
