    Im learning IP addressing for the first time as I pretty much only really knew about host and network IDs. And Ive moved onto CIDR (which I still need alot more practice on) and I can only really calculate it with pen and paper.. Im wondering if you wizkids and mathematical geniuses can do this all from head? Ive only just learnt binary also, looked complicated and took me sometime to find a method that worked best for me and now its a breeze. Im going to have to getup to speed on IP addressing as I need to know it for work.

    I recommend having a look at Todd Lammle's CCENT book if you're learning to subnet. After reading that I find it really easy to do it all in my head. All about the powers of 2.
