Implement and export the ipToInt() and intToIp() functions, which convert the representation of an IP address from an 8-bit format to a 32-bit decimal number and vice versa.

The ipToInt() function takes a string as input and returns a number. The function intToIp() works the opposite way: it takes a number as input, and returns a string.

Examples

ipToInt('128.32.10.1'); // 2149583361
ipToInt('0.0.0.0'); // 0
ipToInt('255.255.255.255'); // 4294967295

intToIp(2149583361); // '128.32.10.1'
intToIp(0); // '0.0.0.0'
intToIp(4294967295); // '255.255.255.255'

Tips

  • IPv4
  • Use the parseInt() function to convert the string to the required number system
  • Explore the possibilities of the toString() method for a number, look at examples
  • Additionally, you can use the padStart() method
