Now that's confusing.. doesn't CIDR supposedly make it so that one IP is no better or worse then another? Why do people base their filtering policies on where things are in the "Classful" space? How is 64/8 any different then 216/8.. they allocate out of both of them, it's a crapshoot what you get since ARIN denys responsibility to provide routable IP space, yet there is space that is "more" routable than other space. -- ------------------------------------------------------------------------------- : Steven Noble / Network Janitor / Be free my soul and leave this world alone : : My views = My views != The views of any of my past or present employers : -------------------------------------------------------------------------------
