255.0.0.0
255.255.0.0
It is called subnetting. Subnetting is taking an address range (for example a class C address range) and assigning VLSM (variable length subnet masks) to break it up into smaller address ranges.
The default subnet mask for the IP address 191.249.234.191 is 255.255.255.0. This is because the address belongs to Class B, which typically uses a default subnet mask of 255.255.0.0. However, if it's using CIDR notation for subnetting, it may also commonly be configured with a mask of 255.255.255.0 for more specific network segmentation.
Variable Length Subnet Masking (VLSM) allows routing protocols to utilize different subnet masks within the same address class by supporting the concept of subnetting at different levels. This characteristic enables efficient IP address allocation and management, as it allows networks to be divided into subnets of varying sizes based on specific needs, rather than being constrained to a single subnet mask. VLSM-capable protocols maintain routing tables that can accommodate multiple subnet masks, ensuring accurate and efficient route determination. This flexibility enhances overall network design and optimization.
To implement subnetting, first determine the network's requirements, including the number of subnets and hosts per subnet. Next, choose a suitable subnet mask that allows for the desired number of subnets and hosts by calculating the available bits in the IP address. Divide the IP address space into subnets based on the selected mask, ensuring that each subnet has a unique network address. Finally, configure the devices on the network to recognize the new subnets by updating their IP addresses and subnet masks accordingly.
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
In a Class A address, the default subnet mask is 255.0.0.0, allowing for a large number of hosts within a single network, but with 16 bits designated for the subnet ID, the subnet mask becomes 255.255.0.0. In contrast, a Class B address has a default subnet mask of 255.255.0.0, and with 8 bits for the subnet ID, the subnet mask would typically be 255.255.255.0. Thus, the key difference lies in the number of bits allocated for the subnet ID and the resulting subnet masks, affecting the number of available subnets and hosts per subnet.
This is a Class B address. So if classful addressing scheme we can say that the default mask of any Class B address is 255.255.0.0. But it may not be always this. There is a concept called VLSM (variable length subnet mask) with which we have the option to give different subnet masks.
The IP address 10.10.10.1 belongs to the private IP address range defined by the Class A network. A common subnet mask used with this address is 255.255.255.0, which allows for 256 IP addresses within the subnet (from 10.10.10.0 to 10.10.10.255). Other subnet masks, such as 255.255.0.0 (Class B) or 255.0.0.0 (Class A), can also be used, depending on the specific network design requirements.

That would be a class E network, E networks do not have defines subnet masks or networks. Just a range (240.0.0.0 - 255.255.255.255).
In computer networking Math and binary operation are used in calculating subnet masks or in subnetting or in supernetting etc.
Custom subnetting is the process of dividing a larger network into smaller, more manageable subnetworks (subnets) tailored to specific organizational needs. This allows for efficient IP address allocation, improved network performance, and enhanced security by isolating different network segments. By defining subnet masks and determining the size of each subnet, network administrators can optimize resource usage and control traffic flow within a network.
