How are IP addresses usually written?

There are two versions of Internet Protocol (IP) present in which the IP address are written which are IPv4 and IPv6. The numbers in IPv4 are 32 bit long while in IPv6 the numbers are 128 bits long.

So let's see IPv4 addresses

IP addresses are written in human readable form. There are 4 groups of 8 bits which represent the corresponding decimal numbers. These groups are separated by (.). Since there are 8 bits hence the numbers range is 0-255.

for ex: - 124.45.65.210

There are 3 dots the numbers are in the range of 0-255. There should be no leading zeroes present in the IP address.
