one thing i dont undersrand. the ip starts with 173. so i thought this should be a class B address which has a subnet mask of 255.255.0.0 not 255.255.255.0 . pls help

@vszabad In IPv4 routing's early formation people were limited to "classful routing." Today with classless inter domain routing (CIDR) you are not limited to the classful schemes.

I have no certifications yet (in a Network+ training course now), but this was quite simple.

Good call on finding the magic number with the last network bit.

[danscourses]

@SyncPK Cheers. Good for you, the Network+ is tough because it is such a broad range of subjects.

Thanks a lot for these Cisco tutorials I am currently doing CCNA 1 and having difficulty with subsets. The magic number technique has really helped me understand subnetting allowing me to easily work out this problem.

@danscourses is it safe to say, network+ and A+ certifications were nice to have in the 90's, but now a days....... better to just go for ccna
