The valid IP addresses are 192.168.1.1 and 8.8.8.8. An IP address consists of four octets, each ranging from 0 to 255. Therefore, numbers like 257, 312, and 456 are invalid.

A class C network has 256 addresses. The range for a class C network is from 192.0.0.0 to 223.255.255.255, and the first three octets are used for the network ID, leaving the last octet for the host ID. This gives us 2^8 (256) possible addresses, but the first and last addresses are reserved for network and broadcast addresses, respectively, leaving 254 usable addresses.

Class B IP address has the first two octets reserved for the network ID and the last two octets for the host ID. The range for a class B network is from 128.0.0.0 to 191.255.255.255.

The flag field is used to indicate that the datagram is allowed to be fragmented or to indicate that the datagram has already been fragmented.

The IP address assigned to a device would depend on the network it is connected. The network determines the range of IP addresses that can be assigned to devices.
