since the first 3 bits are specially preserved for the class of the internet or network.
0-127 For Class A
128-191- For class B
191-233 For class C
given ip address since the first three bits are: 172(128-191)
therefore it is of CLASS C
That depends on the subnet's subnet mask.
When forwarding packets to a host on a different subnet, the local host uses the address of the default gateway, which is typically a router within the same subnet. The default gateway serves as an intermediary that routes traffic from the local subnet to other subnets. This address is configured in the network settings of the local host. Packets destined for outside the local subnet are sent to this default gateway for further routing.

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.
32 host per 8 subnet.
By changing subnet mask..from 255.255.224.0 to 255.255.240.0 Number of subnetworks increase and the number of host in each subnetwork decreases
255.0.0.0

Convert the subnet mask to binary: 11111111.11111111.11110000.00000000The zeroes tell you which bytes indicate the host; in this case, 12 zeroes allow for 212 = 4096 different IP addresses within the subnet. Of these, two (the first and the last) are unusable for a host, so you have a maximum of 4094 hosts.
To determine the network or subnet address of an IP address
The default subnet mask for this address - a class A address - is 255.0.0.0 (same as /8).
If you mean the range of IP addresses in the subnet, additional information is required. Specifically, the subnet mask.
