Question

If the IP header is 192 bytes long, what will be the value of the “HLEN” field?
a. 4
b. 6
c. 32
d. 192

Answer 1

Answer:

48

Explanation:

IP header = 192 bytes (Given)

Field = HLEN (Given)

An Ip header is the header containing the various data like the source ip address, the destination ip address and the ip version.  

HLEN is in the TCP/ IP protocol having a value of 5

Thus, the total number of headers = 5 × 4  = 20 bytes.

Value of the HLEN field = 192/4

 = 48

Therefore, If the IP header is 192 bytes long, the value of the “HLEN” field will be 48.

Answer 2

Answer:

b) 6

Explanation:

HLEN is number multiplied by 32 is ip header length

x*32=192

x=6

HLEN=6
