Now IPV4 is represented by a 32-bit unsigned integer, which is typically displayed in a point-and-click manner, dividing the IP address into 4 parts, each of which is 8 bits, which is represented as an unsigned integer (so there is no need to use a plus sign). As 10.137.17.1, we are very familiar with the IP address, an IP address string no space appears (because to be represented as a 32 number).Now you need to use the program to determine whether IP is legitimate.Determine if it is legal ip#in
