<strong data-start="”41″" data-end="”361″">No, this is not a limiting factor when planning an IPv6 network. On the contrary, it is a simplification. In IPv6, each subnet is assigned a default /64 prefix, which provides 2⁶⁴ possible addresses — about 18 quintillion addresses. This means there are far more addresses than needed for all the hosts in a network.
