Answer:
256 subnets
Explanation:
In networking, subnetting is used by network technicians or administrators to reduce or prevent excessive waste of IPv4 addresses. The formula for subnetting is;
Subnet = 2^number of bits borrowed
If the number of borrowed bit is = 8
Then subnet = 2^8 = 256 subnet
The previous subnet mask for the class B address is 255.255.0.0 but the new subnet mask becomes 255.255.255.0 which is equivalent to a class C address.
