Cisco Training CCNA IP Addressing - Part 7

Comments on 'Cisco Training CCNA IP Addressing - Part 7'

1. OMG this is so great! And thanks to you too ProgramJava!!
2. Once u understand that freaking table u realized how great
   it is... i will use it too...lol
3. That table is brilliant - I will use this for the CCNA
   exams.
4. WAT?
5. I'm not quite sure I understand the use of the look-up
   table(s).
6. Wouldn't it have been easier to just figure out what 29 bits
   equals and then subtract the last octet from 256 and then
   subtact two from that? I'm brand new to IP addresssing.
7. net ID and broadcast id for each subnet..
8. 1010010111
9. This video, compared to the others, is really bad. It will
   makes lost so many time. the answer is really fast and
   simple. you have a subnet mask of 29 and the IP address is
   32. So you have 32-29= 3 bits for the hosts. So you calcute
   2^3=8 (2 position (0 or 1) for each of the 3 bits). Then you
   remove 2 because of the address of the network itself and
   the address of the multicast. So you have 8-2= 6 the final
   answer. To resume, to find the answer you just make: 2^3-2
10. These videos are excellent!
11. I really like your videos, but unless they ask tons of these
    questions (to reuse the lookup table), then you could just
    take 2^(32-(subnet number))-2 and that is the number of
    hosts. Therefore, 2^(32-29)-2 = 2^3 -2 = 6, seemse much
    quicker, but without the lookup table you presented I
    probably would have never thought about that.
12. perfect & easy & quite cool =)
13. Disagree - you want to be CCNA, you need to know this stuff
    inside out.
14. The method works and is presented in a style that is about
    %1000 superior to %95 of youtube videos availalbe IF you can
    even find one on this subject so if you rate this you should
    rate it relative to other youtube video i.e. 5 star
15. hahaha, i agree these r of great help for my ccna :)
16. Who here is CCIE raise your hand. If not shut up and be
    glad for this free video.
17. So that the broadcast and network addresses are not being
    counted on the number of hosts. :)
18. On what basis is the 2 used to subtract 2,4,8? at the end
    of the vid
19. some of the first videos are great , but has an introduction
    to the CCNA course its very confusing , it seems like your
    making people think they need to know to much for somthing
    simple which is more off puting then infomational.
20. thanks soleilenveierge Im new to CCNA and i found this video
    confusing. Your explanation is a faster way to arrive at the
    solution.
21. I think the previous posters are missing the point that his
    method can be used to answer any question of this type. I
    don't think he's advocating you write out the full table to
    answer one question, but rather to have it available as a
    resource to answer multiple questions of this type.
22. This is an RIDICULOUS explanation that can only confuse
    anyone who wants to understand the concept !!!!!! Six minute
    of an explanation that takes really 20 seconds. 32-29 = 3
    bits. 3 bits gives 8 possibilities -network - broadcast =
    6. All your other videos are good. You explain well but
    this one is a big mess.
23. I m sorry, simple you can said 32 bit - 29 = 3 3 bit for a
    host mean 2^3 -2 witch is 0 to 6 but thank you your videos
    are excelent!! I lear much with it. Congratulations.
