RE: Pitfalls of annoucing /24s

This is a part of the problem. I realize that large ISPs are probably
against micro-assignments so that they can continue to use address space
to treat customers as indentured servants. I guess they can skip
Chicago and just filter out any micro-assignments that ARIN may one day

My biggest gripe on this topic is about ISPs that assign /24's to
multi-homed customers, but filter out /24's received from peers. Verio
(the example of the day) accepts /24's (that they likely assigned) from
customers but filters these out from others. Are they expecting their
peers not to filter these /24's or do they really care? I suppose if
their peers adopt filtering policies such as theirs, they can just tell
their customers "We accept your /24, but the other guy is filtering it
