The combination of ip address and subnet mask is invalid

I go to 'wan setup' and choose 'Internet connection type' of 'static IP' and then enter my known IP address, subnet mask, Default gateway and DNS details and as soon

Here are a few examples of IP addresses and Subnet Masks in combination: If the Subnet Mask is 255 in the first part then the first part of the IP address shows what IP network the address belongs to. If the second part of the Subnet Mask is also 255, then the second part of the IP address is also part of the IP network. Upon further investigation, a technician notices that the user has an IP address/subnet mask combination of 192.168.204.255/24. The default gateway for the network is 192.168.204.254. Which of the following could the user's IP address be changed to so that they could connect to the network? A. 192.168.204.0/27 B. 192.168.204.1/27 C. 192.168.204 address the correct subnet, and probably not with the correct mask. > Anyway, I am aware of the "route print" as I am aware of "arp -a", but lets > not confuse routing with routes and routing tables with broadcasting and "The combination of IP address and subnet mask are invalid. All of the bits in the host address portion of the IP address are set to 0." But they're not all set to 0. That would be a subnet mask of 255.255.255.255. Even then, that too is a valid subnet mask, consisting of a network of 1 IP address. Is there a way around this? A registry hack maybe?

If you must have a /23 network, then you cannot use those addresses because they are not usable addresses, and they are in two separate networks. If you shorten the mask length (smaller network, but more network hosts), then you can use those addresses.

The purpose of a subnet mask is to demarcate the portion of the IP address that contains location information and the portion that contains identity information. The reason why the mask given is invalid is because it is not contiguous.
