Probably going to start with subnetting first

I'm thinking of starting with subnetting first for the CCENT. I want to get that down and get it out of the way because its going to be all over the place on the test probably. When I took it years ago I used the Todd Lammle method which was awesome. I did not pass back then but im giving it another go. Then I will go through the rest of the material. Is anyone else using this approach? I just think this will work better for me. Have exam scheduled for the 29th of this month. I have been through classes and all before and work as a L1 network infrastructure Tech.

Almost everything to do with prepping has to do with subnetting. There are so many websites that you can do a few problems or more each day. With that being said, I do not think I would specifically go after it first...just study all the topics and as you come across subnets in problems you can figure out ranges and so forth.

Ok thanks so much guys. I will check out that video too.

just memorize your block sizes and you can do it in your head. Forget the nonsense about writing down a chart and all that nonsense.

@mikeybinex, what do you think the best sub netting method is for remembering block sizes. I was looking at the one in Todd Lammles book and I like the one posted in the video above too.

mikeybinec

use anything you want subnetting.org or whatever... The block sizes are the same no matter which octet you are in.. OK replay time from the DeathImage thread:

Cmon man.. just do the block sizes!! OK, here we go:

Test question comming up!!

Given the IP address 20.188.13.50 /12, what is the network ID and two valid hosts?

A) 20.192.0.1

20.177.255.255

C) 20.190.1.255

D) 20.255.255.255

E) 20.176.0.0

READY!!! START THE CLOCK!!

A slash 12 means it hits the 2nd octet and has a block size of 16. How many 16s can we fit under the 188 WITHOUT GOING OVER? 11!11 11 times 16 = 176

WE GOT OUR NETWORK ID 20.176.0.0 /12

Our first host is 20.176.0.1

add a block of 15 to the 176 to come to the end of our network and you have 20.191 Now put in the host addreses in the third and 4th octet 255.254 for the last host and 255.255 for the broadcast address

Last host address is 20.191.255.254

Bcast address is 20.191.255.255

MIKEY DID IT 30 SECONDS OR LESS

Awesome. this looks like pretty much the way I learned years ago. Perfect and makes sense. Thanks so much.

Looks like you went to the same school I went to in El Cajon. I used to live down there. I took the class for a short time at Cuyamaca back in 2010 I think.

I took the class for a short time at Cuyamaca back in 2010 I think.

lol! I started in 2009 so surely we know each other?

In a couple of weeks Im gonna go pass the ICND2 then head back to Cuyamaca NetAcad and take CCNP. I'm kinda trying to decide between NP and MCSA

Oh man thats awesome. I miss it down there want to go back. Im in LA now. Im trying to decide if im going to do virtualization/CCNA Data center or just roll into CCNP with the Chris Bryant material. Good luck either way man. I know the job scene is tight down there but with a little Cisco you should be good.
