I think those nets can be killed in BGP, so a route to/from couldn't be advertized/established. I suppose this would be the advantage to a spammer wanted to hide using one of these nets. >Or is it only possible for those IPs to be used on a private network >before being sent out to the Internet, which is how it would get into the >Received headers? most routers will route anything, unless programmed not to the point is that these nets are not for public use, so using them is not expected behavior. So don't use them if you wante to receive expected treatment. Len
