Hi,
RIPE NCC reserves a /29 for every /32 allocation, right?
No, they don't. It used to be like that a long time ago, but these days it is just sparse allocation. The change was announced at RIPE-61 (http://ripe61.ripe.net/presentations/331-Update_RIPE_NCC_R61.pdf) which was in November 2010.
I think they still reserve 3 bits, even with the sparse allocation algorithm.
This is easy to find out, since delegations are public data. AFAICT: - Allocations (at least up to and including /29s): reserve a /26 (for some reason the allocated /32 isn't the first one in the /26) - Assignments (at least /48s): reserve a /46 $ grep 'ipv6.*201310' delegated-ripencc-extended-latest ripencc|AT|ipv6|2a00:f020::|32|20131001|allocated ripencc|SE|ipv6|2a00:f060::|32|20131001|allocated ripencc|NO|ipv6|2a00:f0a0::|32|20131001|allocated ripencc|QA|ipv6|2a00:f0e0::|32|20131001|allocated ripencc|AT|ipv6|2a00:f120::|32|20131002|allocated ripencc|RU|ipv6|2a00:f160::|32|20131002|allocated ripencc|BE|ipv6|2a00:f1a0::|32|20131002|allocated ripencc|SE|ipv6|2a00:f1e0::|32|20131002|allocated ripencc|ME|ipv6|2a00:f220::|32|20131002|allocated ripencc|AZ|ipv6|2a00:f260::|32|20131003|allocated ripencc|RU|ipv6|2a00:f2a0::|32|20131003|allocated ripencc|GE|ipv6|2a00:f2e0::|32|20131003|allocated ripencc|NL|ipv6|2a00:f320::|32|20131003|allocated ripencc|NL|ipv6|2a00:f360::|32|20131003|allocated ripencc|IT|ipv6|2a00:f3a0::|32|20131004|allocated ripencc|RU|ipv6|2a00:f3e0::|32|20131004|allocated ripencc|DE|ipv6|2a00:f420::|32|20131004|allocated ripencc|RU|ipv6|2a00:f460::|32|20131004|allocated ripencc|GG|ipv6|2a04:6b40::|29|20131001|allocated ripencc|NO|ipv6|2a04:6b80::|29|20131001|allocated ripencc|NL|ipv6|2a04:6bc0::|29|20131002|allocated ripencc|ES|ipv6|2a04:6c00::|29|20131002|allocated ripencc|BE|ipv6|2a04:6c40::|29|20131003|allocated ripencc|RO|ipv6|2a04:6c80::|29|20131003|allocated ripencc|SE|ipv6|2a04:6cc0::|29|20131003|allocated ripencc|SE|ipv6|2a04:6d00::|29|20131003|allocated ripencc|CH|ipv6|2a04:6d40::|29|20131004|allocated ripencc|PT|ipv6|2a04:6d80::|29|20131004|allocated ripencc|NL|ipv6|2a04:6dc0::|29|20131004|allocated ripencc|RU|ipv6|2001:67c:2be0::|48|20131001|assigned ripencc|PL|ipv6|2001:67c:2be4::|48|20131003|assigned ripencc|NL|ipv6|2001:67c:2be8::|48|20131004|assigned ripencc|PL|ipv6|2001:67c:2bec::|48|20131004|assigned Tore
