Hi,

I have just added an update to the "strict" filter list of my IPv6 filter
list recommendations on http://www.space.net/~gert/RIPE/ipv6-filters.html

The new thing is that inside 2001:500::/29, the "strict" list is now
permitting /48s.  This is because 2001:500:: is used for ARIN 
microallocations, and /48s are the "normal" allocation boundary in there.

Two networks are already announced from within that block, 2001:500::/48
and 2001:500:1::/48, and some ISPs promtly can't reach them due to 
too tight filtering.   

So if you filter very strictly, please adapt your filters for that block.

(Thanks to Carlos Friacas for pointing that out to me).
