Re: 291 IP Addressing Help

My problem is that I cannot see, understand, the uses for subnetting. In
the context of the MS Training Kit is goes on about the ISP allocates you a
block of addresses.

I think what I, and probably every else, would find useful is some real
world experience. I work for a small IT firm that only administers small
networks.

I think one day the penny will drop and it will all become clear, but until
then I keep on trying to make sense of it all on my home network

I'm having the same problem getting my head around it all and this site
has helped.

I have read the 291 MOAC and have utilized STS in my training for 291
exam.
I took it June 8th and failed with a 572. Although not bad concidering
I
have had little time to study since my class is moving quite fast and I
just
started a new job in the IT field my weakest topic was IP Addressing. I
was
very strong in RRAS and Network Security I was somewhere under 50% with
the
IP addressing and that was my lowest. If anyone has any pointers or
anywhere
I can go to get extra material to help me study for the exam again by
this
Friday would be greatly appreciated. Again it was the IP addressing
part of
291 that got me. DHCP and DNS, I thought I was knowledgeable in these
subjects but it looks like not good enough.

Thanks,

Hi George and Fraser

I'm not planning to take my 291 exam anytime soon as I need a lot more
networking experience, but one of my degree modules was in networking and
I was lucky in that the subnetting part just "clicked" with me and I found
it enjoyable (yes, I know I need to get out more!!)

I found it easiest to break IP addresses down into binary so I could
identify the common "network" bits, compare them with the subnet mask and
check whether IP addresses were in the same subnet or not. It will also
help speed up your calculations if you commit the following bit patterns
to memory:-

10000000 = 128
11000000 = 192
11100000 = 224
11110000 = 240
11111000 = 248
11111100 = 252
11111110 = 254
11111111 = 255

And possibly:-
11010000 = 208
10110000 = 176
10100000 = 160
10010000 = 144

Hope this helps.
