Answer 1

1.IP address consists of 4 octets seperated with "."

2.We can convert hexadecimal numbers to binary by grouping each hex digit with it's equivalent 4 bit binary representation.

By combining 1&2 we can represent (C22F1582) as (C2.2F.15.82) in groups of 8 and dotted decimal form.

In binary,we can write(11000010.00101111.00010101.10000010}, in decimal it becomes{194.47.21.130}
