    Hello everybody.
    I am back after a passing my CCNA. I had a bit of time off, just got married and honey moons and all that stuff, the rest was nice but here I am again with more questions.
    I am doing this netscape skills persuit and I have a pdf file with this;

    GH1 router = 200.200.200.18/28
    I know /28 = 255.255.255.240

    GH2 router 200.200.200.18/34
    I know that /34 = (ops) no, I do not know what this means at all

    GH3 router = 200.200.200.18/50
    I know that /50 = (ops) no, I do not know what this means at all

    What on earth are they talking about? /34 and /50????

    There is no /34 or /50 in IPv4 subnetting.

    That's what happens when you study substandard training materials. 8) Stick with the good stuff. ;)

    Does anybody minds to share some lights please?
    I have done sone googling and IPv6 comes in 4 groups of 2 octets separated by a :, so in this case the 200.200.200.18 is not IPv6.
    How can I work this out, 200.200.200.18/50, anybody? PLease?
    Cheers

    Two things spring to mind:

    1. Either they have done a misprint on the CIDR or
    2. They have done a misprint and that's suppose to be a IPv6 address instead of a IPv4 address

    That doesn't look even remotely like an IPv6 address - it's just shabby prep material

    Yes I am sure I have passed my CCNA and sorry but I read BMs message in a hurry that I didn't even seen his answer.

    This is material given to me by CISCO at Click here I thought they are the good material???

    I studied CCNA curriculum 3.1 and it did not included IPv6.
    About subneting I done it up to a /30 which gives 2 valid IP addresses, and mostlu used on a point to point serial connection but pardon me if I got it wrong?

    Anyway, thanks for the comment.

    That's quite right - /30 bit subnet masks are indeed used on PTP connections. Still doesn't explain where they got the other spurious subnet masks from - and if this is indeed 'official' Ciso material, then those are some pretty piss-poor typos to escape their proof-reading department...
