networking - Subnet and host in network subject -

i have question:

into how many subnets can separate network id 10.1.0.0/14 if maximum number of hosts in each subnet 18?

i found 64 subnets i'm not sure because part of maximum confuses me little bit.

please can me?

there 32 bits in ipv4 address , since 14 fixed in network id means 18 left floating. leaves 2 18th power addresses free 262144. since each subnet has @ 18 hosts , need 1 more broadcast means need 19 addresses per subnet. since can make subnets powers of 2 need use 32 addresses each subnet (/5 subnets). answer 262144/32 = 8192 subnets.
