Query regarding ip address

Question

As let their is subnet

255.255.192.0

As 255.255.11000000.00000000

Possible network=4

Possible host =2^14

Where valid host in each network = 2^14-2

What will the first subnet and first octet?

What is meant by octet?

Answer 1

Well your question is not accurate .

With subnet mask 255.255.192.0 one more information we require is which class is this .

As per me when you said 4 subnets , it is supposed to be class B network there fore network bits is 16 bits and subnets bits is 2

Therefore , total subnets possible from 2 subnet bits are 4 . And no of network possible =2^16

Hence my answer takes the supposition it is B class address subnet mask

Now no of Host possible = 2^14 - 2 where 14 are the host bits

Coming to your doubt on octet ,  octet means 8 bits or 1 bytes , so here one octet means 1 byte of ip address i.e for example in ip address 1.2.3.4  1, 2 ,3 and 4 each are octets .

Now first subnet possible from this subnet mask 255.255.192.0 of class B address is

 suppose your network is class B first network possible 128.0.0.0

128.0.0.0/18 ------ 128.0.63.255

 

Your question is incomplete and almost everything in my answer is supposition

Comments

If you are sure Total no of network are 4 the. First two bits are network bits and rest 16 are subnet bits , therefore no of subnets possible are 2^16 .

And if we start from first ip address 0.0.0.0 then first subnet is 0.0.0.0 ---- 0.0.0.63.255 /14
