If we follow that, we should just state "Don't allow spoofed IP 
Addresses!" and leave it to the individual to figure it out. BCP38 
leaves that premise by mentioning ingress filtering as well as 
mentioning some issues with DHCP. If nothing else, it should have an 
extensive appendix to point people to the correct documentation for

They are not, and I can think of quite a few people who would stare 
blankly at you for making such a statement. Of course, I can think of 
plenty of people who we'd like to see implementing BCP38 concepts that 
would need you to define ingress and egress.

Fact: Ignorance is abound on the Internet, even in the running of networks.

If you want a solid change, we're going to have to educate people; 
especially those who are not on NANOG, don't know about the IETF, and 
have never heard of an RFC or BCP.
