Yes, Geert Jan, but if you look at the list I prepared, you'll note that the only chunks of old style Bs that are 18-bits long all come from one home-AS and most are in a pair of old-style class Bs which easily could be aggregated into a single /15 with the loss of some routing specificity (which is lost anyway when that provider's internal metrics don't propagate to its external peers). The remainder of the 'chunks' of old style Bs are all longer than 18 bits, and most are /24s or /26s, and I see none at all that appear difficult to aggregate, or which look like anything other than leaks due to misconfiguration. If you get to the point where someone needs to have a /18 in the old-style class B space and it can't be aggregated, we can return to this. Sean.
Hallo, the Municipality of Zuerich has got assigned 1/2 class B in April this year after a long discussion with RIPE NCC. They will soon get onto Internet. I need to be sure that this address space is routed on the Internet. Sean, Geert-Jan, could you comment, please.
