That's precisely the reason why > the 6RD proposal allowed for extension up to that exact size:
for a customer, I had a request for a /28 opened recently and were offered to start with a /29 and maybe resize it to /28 depending on outcome of 2015-03. I asked back if "resize" means new allocation so renumbering and received the following reply for RIPE-Staff: > We actually reserve 3 bits for each allocation so in future if > needed your user would have access up to a /26. I just downloaded ftp://ftp.ripe.net/ripe/dbase/split/ripe.db.inet6num.gz and grep'ed for /29 $ grep "/29" ripe.db.inet6num | sort I did not validate each and every line, but paged thru the output and it actually seems that the allocations made are all with a following reserved space that they can be grown upto /26: inet6num: 2a06:d00::/29 inet6num: 2a06:d40::/29 inet6num: 2a06:d80::/29 inet6num: 2a06:dc0::/29 inet6num: 2a06:e00::/29 inet6num: 2a06:e40::/29 inet6num: 2a06:e80::/29 inet6num: 2a06:ec0::/29 inet6num: 2a06:f00::/29 inet6num: 2a06:f40::/29 inet6num: 2a06:f80::/29 inet6num: 2a06:fc0::/29 Sorry in my last mail I remembered wrongly that it was /27 instead of /26 BR Jens -- Opteamax GmbH - RIPE-Team Jens Ott Opteamax GmbH Simrockstr. 4b 53619 Rheinbreitbach Tel.: +49 2224 969500 Fax: +49 2224 97691059 Email: [email protected] HRB: 23144, Amtsgericht Montabaur Umsatzsteuer-ID.: DE264133989
