Is there a prefix list available listing the IP space of cryptographic
export restricted countries? My google skills are failing me. I'm
required to apply a ban on North Korea, Iran, Syria, Sudan and Cuba.
Thanks for the reply. I'm aware of the limitations of this approach.
For the same reasons you stated (proxy etc), I don't expect this to be
foolproof or accurate. I'm only intending to satisfy a demand to "do
something". We already dictate export requirements in the EULA, but
we need to also attempt to block the embargoed countries.
