Depends on the subnet.
For the subnet of 192.168.1.0, the first usable IP address is 192.168.1.1. This is typical of a default wireless router setup.
Valid usable IP addresses under this scenario is 192.168.1.1 to 192.168.1.254.
0001 0110 001 is the first valid host address of 193.168.22.1.
This is a network address
This is not a valid IP address - a valid IP address has 4 bytes. Also, you can't guess the subnet mask from looking only at the IP address; there are usually several options.
4.1 to 7.254
15.242.55.6227 is an invalid IP address.
This is a network address.
This isn't a valid CIDR address, so I assume it is: 192.168.1.162/7 That would yield a subnet mask of 255.255.255.254
172.16.0.0. The first ip address within this subnet is 172.16.0.1
The address before the next valid network address will be the broadcast address For Example:192.168.1.64 the broadcast address is 192.168.1.127
If (for example) the first 20 bits of the subnet masks are "1", then any IP address that shares the same 20 bits with the IP address of my computer is in the same subnet.Note that a subnet only indicates the size of the current subnet, the subnet in which your computer (for example) is located. Other subnets of a network may have different sizes; this can't be ascertained just by looking at you IP address and subnet. Nor is it relevant for your computer: The computer only has to know that anything outside the subnet has to be sent first to the default gateway - the server or router that connects your subnet to the remainder of the net.If (for example) the first 20 bits of the subnet masks are "1", then any IP address that shares the same 20 bits with the IP address of my computer is in the same subnet.Note that a subnet only indicates the size of the current subnet, the subnet in which your computer (for example) is located.

In a 24 bit subnet (subnet mask = 255.255.255.0), the address 192.1.6.255 is the broadcast address for the subnet 192.1.6.0/24.
This assumes you know how to subnet. On a network with 190.254.0.0 as a host address and using 11 bits for the subnet mask. The network address is 190.224.0.0 and the end of the range is 190.255.255.224. The address you show is within this range so cannot be the network address. If you don't know how to work this out manually use a subnet calculator such as the one on this URL: http://www.boson.com/FreeUtilities.html
