Question

The IPV4 address has been written as { 127, 0, 0, 1 }
How to write the loopback address in IPV6 in this format. Do I need to take a 16 sized array???
Isnt there any better way ???

Answer 1

Well, IPv6 has many “shortened” forms, so that a loopback address can be written as ::1 – however, in an array, you’d need to spell out the entire thing (16 * 8 = 128 bits):

{ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1 }
