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
To configure Variable Length Subnet Masking (VLSM), you start by determining your network requirements, including the number of subnets and hosts needed for each subnet. Next, you allocate a larger subnet, then divide it into smaller subnets using different subnet masks based on the specific needs of each segment. Assign IP addresses accordingly, ensuring that each subnet has a unique network address and subnet mask. Finally, update routing protocols if necessary to accommodate the new subnets.
The IP address 172.30.0.0 is a private IP address in the Class B range, which has a default subnet mask of 255.255.0.0 (or /16). If you use the default mask, you can create 65,536 addresses (2^16), allowing for 65,534 usable hosts per subnet (subtracting 2 for the network and broadcast addresses). If you further subnet this address, the number of subnets and hosts per subnet will depend on the subnet mask you choose. For example, using a /24 subnet mask would give you 256 subnets with 254 usable hosts in each.
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.
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
A network class refers to a categorization of IP addresses within the Internet Protocol addressing scheme, used to define the range of addresses that can be assigned to devices within a network. The primary classes are A, B, and C, each distinguished by their default subnet masks and the number of available host addresses. Class A supports large networks, Class B is suited for medium-sized networks, and Class C is designed for smaller networks. This classification helps in routing and managing IP address allocation efficiently.
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.
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.
IP addresses are categorized into five classes: A, B, C, D, and E. Class A (1.0.0.0 to 126.255.255.255) is designed for very large networks, with a default subnet mask of 255.0.0.0; an example is the IP address 10.0.0.1. Class B (128.0.0.0 to 191.255.255.255) accommodates medium-sized networks, using a default mask of 255.255.0.0; an example is 172.16.0.1. Class C (192.0.0.0 to 223.255.255.255) is intended for small networks, with a default mask of 255.255.255.0; an example is 192.168.1.1. Class D (224.0.0.0 to 239.255.255.255) is used for multicast groups, while Class E (240.0.0.0 to 255.255.255.255) is reserved for experimental purposes.
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.
