You are clear as usual. Because you touched the "subnetworking" topic,
I submit you a question, coming from the IP-Subnetworking mini-Howto:
The author explain how to split in 4 part a single class C network
This is the text:


  Network Broadcast Netmask Hosts 62 62 124 (see note)

  Note: the reason the last network has only 124 usable network
  addresses (not 126 as would be expected from the network mask) is that
  it is really a 'super net' of two subnetworks. Hosts on the other two
  networks will interpret as the network address of the
  'non-existent' subnetwork. Similarly, they will interpret as the broadcast address of the 'non-existent'

But I can't absolutely understand why two subnets are joined in a single
network. Why .192 is a network address of the 'non-existent' subnetwork ?


I'd like to conclude with a positive statement, but I can't 
remember any. Would two negative ones do?       -- Woody Allen
