It is obvious that subnetting is challenging topic, but as human nature eveyone feels certain things are is simple and easy after they understand very well (you name it)
I have been struggling for more than a month now, which may surprise many of you guys, even myself I feel bad sometimes (the length and time spent on this bloody subnetting) however I am now getting right, and therefore I want to share those who are still in need to master subnetting to see this link.

This links will not teach subnetting from A to Z, but it will help to practice what you have learned from other sources.
I really appreciate for the good work here, by posting helpfull stuff, I like those who are here to benefit from, and to assist others*****when some topics frustrate me to understand I just read here, and I found it is not only me who have this problem, then I get relived.
Many Thanks
