Spec says 'the department has a single class C subnet (130.17.105.0/24).... '
Isnt it impossible for a class C network? Class C networks begin with 110----- meaning 192 and upwards no?

Its all too much for me.

fella this forum has been really good to me regarding computer questions. Well not so much my uni questions, but in general. :) I reckon its a good place to come with any sort of question. At it does say general chit chat.

Mt Isa huh. Bad memories about that place. Had my first VW breakdown there. First servo on the left as you come into town from the west. Where my kombi died. Had half an hour to arrange transport for it and for myself to get to nambucca. 35 hours on a bus. not fun.

In short yes it is impossible for it to be a Class C address with that IP.

130..... is a Class B address

1.0.0.0 - 126.0.0.0 Class A
127.0.0.0 - Loopback
128.0.0.0 - 191.255.255.0 - Class B
192.0.0.0 - 223.255.255.0 - Class C
Then onto Class D and E

A Class C must start with first 3 Bits set at 110 so it is impossible for 130. . . to be Class C.

so Im not as thick as I thought. well, better go watch MDA, sleep on it.

Since it is using CIDR Notation on there as well as the IP I would be reading the question again as it maybe reffering to a subnet address within the range of Class C addresses that is has.

I don't see how it could ever be a called a class C though but with a uni question anything is possible. The bit length of the mask at 24 is very Class C though so I reckon there is a typo in there somewhere.
