Diese Nummer sind normalerweise interessant fuer Hosts in solche Netzwerke:
Ry == preferred router address inside the net x.x.x.y
Bz == the broadcast address x.x.x.z
Ha-b == the host address range x.x.x.a - x.x.x.b
where x.x.x is the 3 digit part in NN, e.g. Net.122
The number of networks listed below reflects the number of networks of that particular netmask which fit into a class C style boundary. Of course, the netmasks may be mixed within that boundary as well. Note that not all systems support direct connections to networks with different (variable) netmasks. These networks then have to be connected via modern routers.
Be careful when using highest/lowest subnets (e.g. 0 and 255), and on Cisco routers use ip subnet-zero command.
