Question

If the IP header is 192 bytes long, what will be the value of the “HLEN” field?

Answer 1

Answer:

Ip header is the header which contains the data's such as source ip address, destination ip address and ip version.  

HLEN is in TCP/ IP protocl and it has a value of 5 which means total number of headers equals to 5*4  or  20 bytes.

Now according to the given question :

IP header = 192 bytes

Value of HLEN field = 192/4

                                 = 48 bytes.

Answer 2

The correct answer will be "48 bytes". The further explanation is given below.

Explanation:

• The IP header seems to be the header that includes data including such source IP address, target protocol resolve, as well as protocol edition.  
• "HLEN" would be in the TCP/IP protocol and seems to have a significance of five which means that the overall amount of headers is equivalent to

⇒  5 × 4 thus 20 bytes.

Now, it the given that IP header is equivalent to 192 bytes long

So,

⇒  Value of "HLEN" field = $\frac{192}{4}$

⇒                                        = $48 \ bytes$
