Hello, Thank you very much everyone for all your replies. When Class C space gets used up, wouldn't the filtering policies have to change to allow the same kind of multihoming from the Class A space. Currently, a /24 from Class C is enough to get past filters. However later, a /22 (or is it /20) from Class A would be required to get past filters. Since there are only three /8s left in Class C, I was curious whether filtering policies would change to accommodate this. If filtering policies won't change ARIN will have to change its multihoming PA policy to giving away a /22 instead of a /24. Though officially it is RIR policy not to worry about the routability of an a prefix I guess they do worry about it? Thanks, Harsha.
