I was trying to explain the distinction between a layer 2 segment and a
larger network operating over layer 3 using layer 3 terminology - not
quite confusing the two, but yes, you're right, I should have been
clearer there.
What I would have said if I'd had any sleep would have been: "Layer two
only provides connectivity to machines attached to the same
segment. In the case of a layer three network using TCP/IP this means
the local network segment, such as a 192.168.0.1/24 class C subnet of
255 hosts". This subnet has layer two connectivity - anything further
afield doesn't". ;)
