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...
When calculating CIDR do you put pen to paper?
