The IP address.
Devices in the same VLAN are part of the same subnet, or "group". (The fact of belonging to one VLAN or another is, to a certain degree, independent of the physical location, thus the name "virtual".)Devices in the same VLAN are part of the same subnet, or "group".

A portion of a network that shares a common address component. On TCP/IP networks, subnets are defined as all devices whose IP addresses have the same prefix. For example, all devices with IP addresses that start with 100.100.100. would be part of the same subnet. Dividing a network into subnets is useful for both security and performance reasons. IP networks are divided using a subnet mask.
The subnet mask - expressed in binary - starts with a number of ones, followed by zeros. If (for example) the subnet mask is 255.255.255.0, this can also be written as /24 - that means that the first 24 bits are ones. In this example, that means that the first 24 bits of the IP address (in this case, exactly 3 bytes) are shared by all devices in the same subnet. So, if your IP address is 200.3.85.7, and the subnet mask is 255.255.255.0, all other computers in the same subnet will also start with 200.3.85.
No. 192.168.12.1 - 192.168.12.254 is one subnet (assuming 255.255.255.0 subnet mask)
The subnet mask must be the same for all devices in the same LAN segment. The IP addresses must be unique (different). Also, the default gateway address is usually the same for all devices in the same LAN segment.
No, all subnets must use the same subnet mask
The subnet mask helps determine which part of an IP address represents the network and which part represents the host. It is used by devices to identify whether an IP address is within the same network or needs to be routed to a different network. By using the subnet mask, devices can correctly send data to the intended destination within a network.
To determine if the hosts at 172.20.11.250 and 172.20.12.3 are on the same subnet, we need to look at their IP addresses and the subnet mask. If we assume a common subnet mask of 255.255.255.0, then the first three octets (172.20.11 and 172.20.12) indicate they are in different subnets. Since the third octet differs (11 vs. 12), they are not on the same subnet.
Yes, it must be on the same network segment or you won't be able to route a packet outside of your network segment. --- In simple home networks, the default gateway will be within the scope of the subnet mask. Some devices will enforce this (artificial) requirement. But it's entirely possible to engineer a network with a gateway that is not within the scope of the subnet mask (if the device will allow it). Image two logical networks that run on the same physical network. It's just not a common configuration.
Subnet mask defines our network bit . If we are using a single network then all computers should have same subnet mask as well as the ip address, that belongs to the same network id.
If the other PC is on the same LAN segment then it will have the same subnet mask as yours. A subnet mask is the same for all subnets within a network so that will be the same as well. For other networks it isn't important to know what their subnet is. You could always ask the other user to find out that information if you needed to know.
