Question

What is the size of an IP address ?
1. 4 Bit
2. 32 Byte
3. 16 Byte
4. 4 Byte
5. 16 Bit

Answer 1

Correct Answer - Option 4 : 4 Byte

The correct answer is "4 Byte".

• The size of an IP address is 32 bit or 4 Byte.
• IP address contains 4 octets where each octet separated by .(dot).
• IP Address is either four-byte (IPv4) or eight-byte (IPv6) addresses.
• A device attached with IP Address can retrieve by RARP protocol.
• IP Address operates in the network layer.
• IP Address identifies the connection of the device on the network.
• IP Address modifies with the time and environment.
• IP Addresses can be found by a third party.

Let's take an example-

10.1.2.3 (a decimal form of IP address)

Binary Equivalent of the above number will be-

00001010.00000001.00000010.00000011

here, we can see 4 Octet separated by Dot Operator.

With this 32 bit IP address, we can actually generate 2^32 IP Addresses.

Which is Approximately more than 4 Billion Addresses.
