Translations:Help:Range blocks/IPv6/8/en

So in many ways IPv6 /64 rangeblocks are akin to blocks of single IPv4 addresses, as a /64 subnet is the norm for connections, although sometimes end-user allocations will include multiple /64 subnets. So generally speaking IPv6 /64 rangeblocks are recommended, as blocks of single IPv6 addresses can be easily circumvented by users with minimal technical knowledge, and normally the risk of collateral damage is low. But be aware that like in IPv4, where a single static IPv4 address may supply a household or institution of some kind, a static IPv6 /64 range may also supply a household or institution, so multiple users can be affected by /64 rangeblocks.
