The global visibility point you address isn't that hard to solve. Most service providers you buy service from, if you tell em you're going to multihome to multiple providers, well they all know that a mask longer than /24 id to be filtered for sure and will allocate a /24 just based on multihoming, even if a smaller portion of the ips is all that is needed. Problems occur when you try to announce the /24 out of classful A or B space.
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 : -------------------------------------------------------------------------------
