An IPv4 address provides what two pieces of info encoded within the same value
The network number (network ID)
and the host number (host ID)
what is a prefix
a prefix is a 32-bit value with a given number of contiguous bits all set to 1
what would the binary value of a /24 prefix be
11111111 11111111 11111111 00000000
what would the binary value of a /16 prefix be
11111111 11111111 00000000 00000000
express the /24 prefix in dotted decimal notation as a subnet mask
