how to determine subnet mask

, that subnet mask set how much appropriate? Let's set out a formula first.2 m-Time Square =560First, we determine that 2 must be greater than 8 square, because we know that 2 of 8 is 256, that is, the number of Class C IP maximum capacity of the computer, we from 9 times a trial 2 9 is 512, less than 560, 2 10 is 1024, it seems 2 of the most suitable. The

Address: Use 21 bits to identify the network number, 8 bits to identify the host number, the front three bits are "110". The first paragraph of the Class C address has a value between 192~223, the first, second, and third paragraphs together to represent the network number. The last segment identifies the host number on the network. Class C addresses are suitable for small networks such as campus networks, and each class C network can have up to 254 hosts.From the above introduction we know tha

company has 530 computers to form a peer-to-peer lan. What is the most suitable subnet mask and IP address?The subnet mask is not mentioned. The previous calculation result is 11111111.1111111100.00000000, that is, 255.255.255.252.0.Now we need to determine how to allocate

an Internet request to the target host instead of forwarding it to the local gateway. In fact, the local subnet does not have the IP address 202.102.11.2, therefore, the 202.102.11.87 host of Company A cannot be pinged to the server of the company. The reason why the company's network cannot PING the network of Company A's subsidiary is mainly because the network mask address of Company A's subsidiary is i

address, and address count, then, the subnet mask is used to determine the network address before consecutive 1, and then the host address for calculation.++4. 206 110 4 0/18 is divided into 16 subnets, with each subnet mask?(Divide it into 16 subnets. According to the

Address: Use 21 bits to identify the network number, 8 bits to identify the host number, the front three bits are "110". The first paragraph of the Class C address has a value between 192~223, the first, second, and third paragraphs together to represent the network number.

two computers are in the same network 192.168.0.0, so can pass, and 2, 3 cases two computers in different networks, so it does not pass.Here is a conclusion: the computer with a direct connection to the network cable or through the hub (hub) or the ordinary switch between the computer to be able to communicate with each other, the computer must be on the same network, that is, their network address must be the same, And the host address must be different. If it is not a network will not be able

different networks, so it does not pass.Here is a conclusion: the computer with a direct connection to the network cable or through the hub (hub) or the ordinary switch between the computer to be able to communicate with each other, the computer must be on the same network, that is, their network address must be the same, And the host address must be different. If it is not a network will not be able to pass. This is like the example we cited above, the same as the North Street tenants because

addressing decision by identifying the network number and subnet number of the destination address. The host part of the IP address is not involved in the routing addressing operation of the router, only an interface that uniquely identifies a network device in a CIDR block. Originally, if only the primary class addresses A, B, and C are used in the network system, and the primary class addresses are not divided into subnets or summarized, the networ

are suitable for small networks such as campus networks, and each class C network can have up to 254 hosts. From the above introduction we know that the IP address is the network number and host number to indicate the host on the network, only in a network number under the computer can be "directly" interoperability, computers with different network numbers need to be connected through gateways. But such a division appears and is very inflexible in some cases. For this reason, the IP network

, 255.255.255.255.192. The computer cannot communicate normally.Figure 3In 1st cases, the two computers are in the same network as 192.168.0.0, so the two computers are in different networks.The following is a conclusion: computers that are directly connected by a network cable, or computers that are indirectly connected through a hub or common switch, must be in the same network, that is to say, they must have the same network address and the host address must be different. if you are not in th

The most direct role of the subnet mask is to determine whether the IP address is within the same network segment as another IP address. Here is a simple look at the basic configuration of IP on a computer IP Address: 192.168.0.5 Subnet Mask: 255.255.255.0 Default gateway: 1

contiguous respectively. The length of the subnet mask is also 32 bits, the left is the network bit, with the binary number "1", the number of 1 is equal to the length of the network bit, the right is the host bit, with the binary number "0" means that the number of 0 equals the length of the host bit. The purpose of this is to allow the mask and IP address to d
