Isn't this the kind of problems that the Doran filters are supposed to prevent?
I understand that it is not to everyone's benefit to filter on the /19
boundary like Sprint does but it seems to be prudent to adopt a /8 filter
on most of the old class A space and a /16 filter on the old class B space.
Other than the need to update these filters as the former class A space is
subdivided I can see no major downside.
Comments?
