There ist also a loose and a strict filter recommendation by Gert Doering [1], but the strict filter is very strict at the moment. It allows only /48s from RIPEs IPv6 PI space 2001:678::/29 for example, although RIPE currently also assignes /47 or /46 from this range. Also there should be some deaggregation allowed. When RIPE allocates a /32 to a LIR and LIR has to deaggregate it for some reason, because he cannot get a second /32, he should be able to use (eg.) 4 bits for deaggreation. I don't want to see a /48 where RIPE allocates only /32 prefixes, but I would accept prefixes up to a /36.
I was thinking about such filters still for v4. Does anyone know if there are any /8's which have no /24 prefixes assigned? I thought about filtering out all deaggregated /24's from such /8's. (I care more about memory of my routers than on a traffic profile of a small company on another continent). Another thing: http://www.db.ripe.net/whois?form_type=simple&full_query_string=&searchtext=193.34.199.0&submit.x=0&submit.y=0&submit=Search This is a normal /25 assigned as PI with route record /25. Are they assigned in any given /8 prefix? If yes, you could easily allow /25's from given /8. -- Grzegorz Janoszka
