IPv6
IPv4
Answers
Answer:
100.00.256 is structured like a IPv4 address, but it’s not a valid address. You can’t have 256 in a byte. The highest decimal value you can store in a byte is 255. I suppose you may have meant 100.0.1.00, but, in general, the first and last addresses in a subnet are used as the network identifier and broadcast address, respectively, so octets with 0, or 255 in the last byte are not usually used as addresses.
An IPv4 address is 4 bytes written as 4 decimal numbers 0…255, separated by periods (.). An IPv6 address is 8 16-bit words written as hexadecimal values 0000…FFFF, separated by colons (:).
The example you’ve given is not a valid IP address in any version, although it resembles the format of IPv4 the closest.
A correct answer is an option (B) Not a valid IP address. 100.0. 0.256 looks like an IPv4 address.
