Is there technically reason for the fact that the length of IP address need be fixed? Now IPv4 address is 32 bits and IPv6 128 bits.
If IP address doesn't need fixed length, we would can structure IPs hiearchy infinite, right?
Think:
0
01
011
02
021
022
0223
0224
0225
to infinite...
!!!NOTE: I don't ask, why IPv4 is 32 bits or IPv6 128. I ask, why fixed length? Please, reopen.
