  Yes, I use the whois databases at arin, apnic and ripe. But, that's now
what I asked. Is there a listing somewhere of, for example, all block
assignments with 66.0.0.0? Or, within 208/8?

  Second, when I have a block of addresses I want to add to my postfix
reject list, is there a way to specify the entire block as a range rather
than one per line?

Thanks,
