As a matter of interest, what's your router address? It's normally either the first available or the last available address in the subnet - e.g. 192.168.0.1 or 192.168.0.254, in your network.
If the router address is itself 192.168.0.1 and you have no more than 4 other devices, then you would not expect to see an address higher than 5.
