A network administrator is allocated the IPv6 prefix $2001:\text{db8}:\text{acad}:4000::/58$ for a new branch location. The administrator needs to divide this block into standard $/64$ subnets for local LAN segments. How many $/64$ subnets can be created from this block?

Cevap

64 subnets can be created from the given

/58

prefix block.

Subtracting the assigned prefix length (/58) from the standard interface subnet prefix length (/64) results in 6 subnet bits (

64 - 58 = 6

). Computing

2^6

yields 64 total subnets.

Adım Adım Çözüm

Calculate the number of subnetting bits.

64 - 58 = 6

bits.

Subtracting the starting prefix length (/58) from the target prefix length (/64) determines the number of bits available for subnetting.

Calculate the total number of subnets.

2^6 = 64

subnets.

Raising 2 to the power of the subnet bit count (

2^6

) provides the total number of valid

/64

subnets.
