Hello Andrzej, Good point. You said that some ISPs are using IPv4 PI address space just because they asked it in their very small ISP status, as being pre-LIR. It would have been much better to change back these addresses to PA already long time. Is there anybody who can suggest a cleaning policy? Of course, vleaning is very difficult whan almost all IPv4 address space have gone... ;-(( Anyhow, the danger og creating too many routing table entries by allocating Provider Independent (IPv6) addresses is still exist and should not be overlooked.

Second point: if ALL IPv4 PI holder would request IPv6 PI then you might
expect another 17K prefixes in the routing table just from the RIPE Region! And this is just the start!
Most ipv4 PI holders have more than one prefix - when first was not enought - they get another. Few ISP in poland get 3-4 prefixes when they weren't LIR.
For ipv6 one prefix is always enought - so 17k is much to much :)

Andrzej
