A network administrator has been given the IPv6 address block 2001:db8:1234::/48. They need to create 256 equal-sized subnets from this block with maximum usable hosts in each block. What prefix length should they use for each subnet?
/60
/56
/64
/52
To create 256 subnets from a /48 IPv6 network, the administrator must allocate 8 additional bits for subnetting because 2^8 equals 256. Adding these 8 bits to the original /48 results in a /56 prefix length for each subnet. This allows for 256 subnets, each with a significant number of host addresses. The other options either provide too few subnets or unnecessarily limit the number of host addresses per subnet.
