Surely you can: $ whois 208.57.0.11 OrgName: MPOWER COMMUNICATIONS CORP.

It is blocked even in my org. I've never heard of such a trend, but just because it's trendy doesn't mean it's a good idea. For example, it has become trendy in some circles to not send bounce messages for non-existant addresses. This is a violation of the RFCs, and leaves users thinking their mail went through when actually a typo made it vanish. Trendy - yes; good idea - absolutely not. Again, I ask - what is the reason? What is gained by doing so. Adam
