Question Details

Given below are two statements:

Statement (I): IPv6 address in computer networking is 4 times larger than an IPv4 address

Statement (II): The IP address gives the location of a device on the Internet, whereas the MAC address identifies the device connected to the Internet

In the light of the above statements, choose the most appropriate answer from the options given below:

Options

A

Both Statement 1 and Statement II are correct.

B

Both Statement I and Statement II are incorrect.

C

Statement I is correct but Statement II is incorrect.

D

Statement I is incorrect but Statement II is correct.

Show Answer

Correct Answer :

Option D

Statement I is incorrect but Statement II is correct.

Solution :

The correct answer is: Statement I is incorrect but Statement II is correct.

Let us carefully evaluate each statement one by one.

Evaluating Statement I:
Statement I claims that an IPv6 address is 4 times larger than an IPv4 address. To check this, let us look at the bit sizes of each address type:

IPv4 address size=32 bits

IPv6 address size=128 bits

Now, while it is true that 128 = 4 × 32 (meaning IPv6 is 4 times longer in bit length than IPv4), the word "larger" in the context of IP addresses refers to the total address space — i.e., the number of unique addresses each version can support.

IPv4 address space= 232 4.3×109 addresses

IPv6 address space= 2128 3.4×1038 addresses

The ratio of the address spaces is:

2128 232 = 2128-32 = 296

This means IPv6's address space is 296 times larger than IPv4 — an astronomically large number, far greater than just 4 times. Therefore, Statement I is incorrect. IPv6 is 4 times longer in bit-length, but it is not merely "4 times larger" in terms of the number of addresses it supports.


Evaluating Statement II:
Statement II says: "The IP address gives the location of a device on the Internet, whereas the MAC address identifies the device connected to the Internet."

This is a well-established distinction in computer networking:

IP Address (Internet Protocol Address) — This is a logical address assigned to a device by its network or ISP. It is dynamic (can change) and represents the device's location within a network or on the Internet. Routers use IP addresses to determine where to send data packets across networks.

MAC Address (Media Access Control Address) — This is a physical address permanently burned into a device's Network Interface Card (NIC) by the manufacturer. It uniquely identifies the device (the hardware itself) and operates at the Data Link Layer. Unlike IP addresses, a MAC address does not change regardless of which network the device connects to.

A helpful analogy: the IP address is like a postal address (tells you where someone lives — a location), while the MAC address is like a national ID or passport number (uniquely identifies the person/device itself, regardless of location).

Since both roles described in Statement II are accurate and well-defined, Statement II is correct.


Conclusion:
Statement I is incorrect because IPv6 is not merely 4 times larger than IPv4 — its address space is 296 times larger.
Statement II is correct because the IP address denotes the device's network location, while the MAC address uniquely identifies the physical device.
Hence, the correct option is: Statement I is incorrect but Statement II is correct.
