subnet mask on router

The subnet mask cannot exist alone, it must be used in conjunction with an IP address. The subnet mask has only one function, which is to divide an IP address into two parts: network address and host address.The subnet mask settin

from one room to another. Similarly, sending information from one network to another must go through a "Gateway", which is the gateway. What is a Gateway, as its name implies, is the "Gateway" connecting a network to another network ". There are also many types of gateways according to different classification standards. The Gateway in TCP/IP protocol is the most commonly used. The "Gateway" mentioned here refer to the gateway under TCP/IP protocol. So what is the gateway? A gateway is essentia

As for subnet division, the subnet mask is odd. 1.0.1.0 -- 1.0.3.255 Fujian Telecom converts the subnet mask to an IP segment 1.0.1.0/24--1.0.2.0/23, if two IP addresses are replaced by binary IP addresses in a general way, or the budget is 0001.00000000.00000001.00, the

Address Example 1: Network address 192.168.10.0; Subnet mask 255.255.255.192 (/26)1. Subnet number =2*2-2=22. Number of hosts = 2 of the 6 square -2=623. Effective subnet?: Block size=256-192=64; So the first subnet is 192.168.10.64, and the second is 192.168.10.128.4. Broa

a router, TCP/IP communication between the two networks is not possible, even if the two network connections on the same switch (or hub), the TCP/IP protocol will determine the subnet mask (255.255.255.0) on the two network hosts in a different network. To achieve communication between the two networks, you must pass through the gateway. If the host in Network a

department. Not long ago, A subsidiary's Network Administrator called and said that when checking local route settings, it was found that "255.255.255.255.192" was set to "255.255.255.0" when the subnet mask parameter was set "; according to the network administrator of Company A, although he sets the parameter table assigned by the company, he accidentally enters the vro

Internet network, a gateway is an intermediary device that connects an intranet to other networks on the Internet, also known as a "router." The gateway address is a channel address that can be understood as the transmission of Intranet and Internet network information. According to different classification standards, there are many kinds of gateways. The gateway in the TCP/IP protocol is the most common, and here we refer to the "gateway" refers to

is actually a packet processing process in a vro. When a packet passes through a vro, the IP address translation process resolves the internal private IP address and translates it into a valid IP address. During address translation, you can perform one-to-one ing based on the pre-defined address table, or translate multiple internal private addresses into one external legal IP address. Because each device in the network has an internal stable IP address, this method has strong network security

assigned by the Company, however, due to operational habits, the router subnet mask parameter is accidentally entered into the Intranet mask address. After the address is changed, the network of Company A can access the server of the company immediately. So far, the network failure mentioned in this article has been s
