The dreaded topic of subnetting...
I'm preparing for 070-291, and am going over some test prep. I thought I had a pretty firm grasp on subnets, but I'm caught up on an idea, and need some clarification.
Lets say my network is 10.0.0.0/20
That makes my mask
11111111 . 11111111 . 11110000 . 00000000 ( 255.255.240.0 )
So my networks can range from
00001010 . 00000000 . 00000000 . 00000000 ( 10.0.0.0 )
00001010 . 11111111 . 11110000 . 00000000 ( 10.255.240.0 )
My question involves the 3rd octet.
If the network in use is
00001010 . 00000001 . 10110000 . 00000000 ( 10.1.176.0 )
and the host portion in binary is
xxxxxxxx . xxxxxxxx . xxxx0110. 00000010 ( x.x.6.2 )
Is the resultant IP address for the host
00001010 . 000000001 . 10110110 . 00000010 ( 10.1.182.2 )
I'm mentally caught up on combining the network and host portion of the binary digits into a final decimal. Just want to make sure I got this straight in my head.
