One of the reasons we use subnetting is because of the limited IP range available right?

Would it theoretically (very theoretically) be possible to have just one worldwide network utilising IPv6?

Ok I have another one.

I'm going through the Prof.Mess videos and have the concept of subnetting in my head just fine (at least for N+ levels...... I think).

The host address range resides between the derived subnet address and broadcast address.

At this moment in time I just have the subnet address and broadcast address as "start, stop" markers on a line of available addresses, can someone please elaborate on what a broadcast address does in the network and I guess what the subnet address is, if it isn't just the address of the subnet itself.

 

have you watched the part two of the subnetting video? it explains how its all worked out with whats the network address, whats the broadcast address etc

See this post from the other day http://www.certforums.co.uk/forums/thread43109.html

 

I haven't watched the second part just yet, I assume the answer is in there right?

Sorry if it was a dumb question, I'm used to these varying nuances being explained there and then rather than "This is just how it is, we'll explain later".

 

You dont need to know subnetting to a very detailed/CCNA level to pass the comptia exams. However, it does help. I would reccomend the videos on youtube by Pancho Training by John Mills Excellent.
