viennaa Posted August 22, 2014 Share Posted August 22, 2014 Hey, Anyone initially find it hard understanding subnets and know of any good resources? Link to comment Share on other sites More sharing options...
+BudMan MVC Posted August 22, 2014 MVC Share Posted August 22, 2014 doing the math can be confusing to some, depends on your math background, etc. Are you having issues just understanding what a subnet is, or doing the math to know what addresses are in say a /22 (255.255.252.0) or 255.255.255.248 (/29), etc.. Here is a good cheatsheet I have posted on my wall for easy reference http://packetlife.net/media/library/15/IPv4_Subnetting.pdf He has lots of cheatsheets there as well.

+John Teacake MVC Posted August 22, 2014 MVC Share Posted August 22, 2014 Yeah I initially did find it hard!! Just comes with experience. http://www.subnettingquestions.com/ Is one site I gave to our apprentices.... Link to comment Share on other sites More sharing options...
Original Poster Posted August 22, 2014 Share Posted August 22, 2014 may I suggest learning basic binary first? this will help you alot when further understanding subnets. hope this helps https://www.youtube.com/watch?v=C17SBPzcMRk&list=UUVEJEY_WctZ643qgUscKyLQ the reason for this is subnetting is done through binary I found it easy to understand once binary was learnt Link to comment Share on other sites More sharing options...
+BudMan MVC Posted August 22, 2014 MVC Share Posted August 22, 2014 I found it easy to understand once binary was learntAgree, your math background can make a big difference.. Which is why I ask - is the math that is causing you pain or just basic understanding what a subnet actually is? Maybe I was just a nerd/geek but binary is something you learn in like junior high is it not.. At least it was when I was in school ;) Guess it depends on what math track your on, etc. ;) Alternate numbering systems are something you learn early on is it not, base 10(decimal), base 2(binary), base 16 (hex) base 8 (octal). I know this was gone over way before highshcool level. And that was 30 years ago - I would think no a days they teach this in like 3 or 4th grade ;) I will ask a friend of mine who is a math teacher when this stuff is taught in school these days. But yeah if you don't get binary and even octal doing the math can be confusing. Link to comment Share on other sites More sharing options...
viennaa Posted August 22, 2014 Author Share Posted August 22, 2014 doing the math to know what addresses are in say a /22 (255.255.252.0) or 255.255.255.248 (/29), etc.. Exactly this, will take a look at the chart for reference! Link to comment Share on other sites More sharing options...
