Is IP v4 address valid?
A valid IP address must be four octets in the form of A.B.C.D,
where A,B,C and D are numbers from 0-254
for example: 192.168.23.1, 172.254.254.254 are valid IP address
192.168.255.0, 255.192.3.121 are invalid IP address
where A, B, C and D are numbers from 0-255
for example: 192.168.23.1, 172.255.255.255 are valid IP address
192.168.256.0, 256.192.3.121 are invalid IP address
