The default subnet masks per class are:
class A 255.0.0.0
class B 255.255.0.0
class C 255.255.255.0
Yes there are default classes. You just have to unlock them. You start off with 3 class unlocks you can use them for each default class. To get more unlocks you just keep leveling up and you get certain unlocks.
A subnet mask that would divide the 172.31.0.0 network into as many subnets as possible and support 600 uers on each subnet would be 255.255.255.0. Each subnet can communicate with each other through the gateway.

that gives you 16 subnets with 14 usable IPs for hosts that is because one is for subnet and one for broadcas in that subnet for example: 192.168.1.0/28 - subnet number 192.168.1.15 -broadcast number usable IPs for hosts - IPs between them that is 14
Computers have a unique IP address to identify them, just like in the real world having 2 equal addresses causes confusion.They don't have their own subnet though, they are part of a subnet which consists of at least 2 pc's. Subnets each have their own broadcast address and default gateway, as well as a limited amount of IP-addresses (determined by the subnet mask) to prevent abuse and to ease scaling.
Because each IP defines certain subnet mask.
It depends on how many subnets you have and how many ports you router has. Usually each port in router is devoted to on subnet, you can do math for your situation.
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
Variable Length Subnet Mask (VLSM) is the new and efficient way to create Networks as compared to the old Fixed Length subnet mask. In Fixed length subnet masks networks there are 2 categories - the basic is A,B & C subnets and the second is fixed subnets that are created from these basic subnets. But in either of the methods there is lots of IP wastage, as different sections of the network will vary in the number of hosts connected to that network. Wastage is more in the first classic way of networks. It is minimized with the help of subnetting, but the problem still exists as some network segments may contain very less hosts but has to use the same subnet masks as the entire network and thus waste IPs. While when we use VLSM different network segments may contain different subnets as per there requirement and while even doing so they will still be able to interact with each other using routers. The 2 main benefits of VLSM are - 1) Because of different subnet masks the broadcast from one subnet is not transmitted to other subnets. Thus saves lots of bandwidth. 2) It saves lots of IP,which is wasted instead. Hope This helps Happy Networking -- By MyNarutoAnime
There are 16 bits available; it is up to you how many of those bits you reserve for the subnet, and how many for the individual hosts within each subnet.
255.255.255.224 would give 32 per subnet or for ex. 192.168.1.1/27 leaving 5 bits or 2-5th power =32
To get the subnet of an IPv4 address you need to know the subnet mask. To write the IP address in binary, simply convert each octet to its binary equivalent and remove the periods (dots). Thus 220.200.190.0 becomes 11011100110010001011111000000000.
