hey guys, studying for me ICND1 and soon ICND2.
Just wondering how far up should I memorize the powers of 2?
Yes I know each consecutive number doubles eachother, however I want to be able to just know the #s off the top of my head to save time.
I was thinking 2^15 would be enough.
Any other time saving tricks for subnetting would be awesome. Thanks

You'll be fine just knowing that. When I was in school, the math teachers encouraged us to memorize up to 2^20, but I always thought to myself, 'Who does that'.
You want to subnet quickly, huh? The secret is to do it again and again and again. Go to subnetting.org for practice.
