greengiant912 Posted February 17, 2010 Posted February 17, 2010 I am currently taking a class (TCP/IP) and we are currently working on how to break down subnets. I am starting to understand it a little bit, but I wondered if anyone out there had a few good tips or tricks they could share with me to get this in my head lol...

fire_storm Posted February 17, 2010 Posted February 17, 2010 (edited) Subnetting is never an easy thing to learn especially IPv6 subnetting. I always used this online calculator to help me through the work http://www.subnet-calculator.com/ Edited February 17, 2010 by fire_storm Share this post Link to post Share on other sites More sharing options...

I always used this online calculator to help me through the work http://www.subnet-calculator.com/ no freakin way, this is the coolest ever....i just started/joined cisco academy yesterday....reading week 1 now, but so far it's all ipv4 Share this post Link to post Share on other sites More sharing options...
fire_storm Posted February 17, 2010 Posted February 17, 2010 (edited) IPv4 subnetting is a little difficult to learn but once you've done it after a while it's not that bad. I have always found that IPv6 subnetting is a little more difficult concept to grasp because there are hex numbers you have to work with plus it's a larger address space and IPv6 has some standards are a little bit different then IPv4.

Guest ajmatson Posted February 18, 2010 Posted February 18, 2010 I'm with fire. IPv6 is a pain in the arse. I just finished my Cisco classes (CJ if you need any help I am a phone call away ) I just started on my MCITP certs and am working on Active Directory now so IPv6 is driving me wacko.

oldfett Posted February 18, 2010 Posted February 18, 2010 My professor did it the with mathematical equations that I understood, but couldn't remember. I do it via binary, which sounds weird but makes ALOT of sense and is easy to remember! I watched this video when I first was learning how to do this method, its a great way to start. I read a few more articles after that to reinforce the idea. I have a link somewhere to a calculator/practice site that is great for practice. Let me know if you need any help. I hated subnetting when I started but now I kinda like it. weird! Share this post Link to post Share on other sites More sharing options...

Packet Tracer is a pretty cool tool, helps a lot to actually put to use the subnets, VLAN... etc Share this post Link to post Share on other sites More sharing options...

Packet Tracer is a pretty cool tool, helps a lot to actually put to use the subnets, VLAN... etc I concur! Packet tracer was the best part of that whole class. I still use it as practice for programming Cisco equipment. Share this post Link to post Share on other sites More sharing options...
Guest ajmatson Posted February 18, 2010 Posted February 18, 2010 hexadecimal huh...thanx so much aj and fire...don't be surprised if i take you up on that aj... i'd pm ya first...well week1 i'm learning packet tracer and how to use it atm, starting first assignment stuff Anytime let me know. Packet tracer rocks but I have a lab set up at home becuase I learn better with full hands on. There is a site I goto as well ( techexams.net ) that has a lot of helpful information and some nice people that will help yo out with problems.

itsernst Posted February 18, 2010 Posted February 18, 2010 Just wait until you start getting into VLAN's. Cisco is the cream of the crop when it comes to VLAN's. Share this post Link to post Share on other sites More sharing options...
