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

the root to the leaves (that is, it itself) the last routed node in the loop, that is, the closer the leaf node of the route project is more preferred to be used, Because it's more precise. After the IP address tree is eventually compressed, the routing nodes are all preserved, and at this point we may have the following subtree:How do we transform this subtree to make it easier to travel from root to leaf

. In addition, for some illegal users who are familiar with attack technology, they often use IP address spoofing technology to forge the IP address of a workstation, but this electronic spoofing technique usually needs to be implemented by means of programming. For example, an illegal attacker can use socket programm

To know how, first to understand a truth, the purpose of learning Network is how to make the network of computers communicate with each other, that is, around the word "tong" to learn and understand the concept of th

" DHCPNetsh interface IP Set DNS "network connection name" DHCP Because I often switch between different networks in my location, such as lan, system Intranet, and Internet (Internet alone, I usually have three ADSLNetwork switching ). I used to set multiple IP addresses of different CIDR blocks on the local machine,

We have also introduced two DHCP relay faults before. I don't know if you still remember them. If you are not clear about it, You can briefly review it. The DHCP relay fault described here is about the problem that clients of different business types cannot obtain IP addresses of different network segments through relay. DHCP relay failure ◆ Network Environment S

IP Control Protocol The IP protocol is only responsible for transmitting IP packets and cannot detect and control problems in the network. These tasks are completed through the Internet control protocol. ICMP (Internet Control Message Protocol) (1) The IP protocol provides the best-effort communication service. (2) T

appended with the frame head and frame end of the data link, and the packet is put into frame. Finally, the physical layer is converted to bits-per-unit data. Therefore, the IP address is the network layer used to identify the logical address of different locations, its length is 32 bits, and at the data link layer is

address that identifies a computer network interface that connects Interent or some dedicated intranet. These addresses are called unicast addresses , and other types of addresses include broadcast, multicast, and anycast addresses, which may involve multiple interfaces and some special-purpose addresses.When the Interent address structure is initially defined, each unicast
