MAC address MAC (Media access control or medium access control) address, which is a translation of media access controls, or physical addresses, hardware addresses, to define the location of network devices. In the OSI model, the third layer of the network layer is responsible for the IP address, and the secon

) used by the NetWare network. Gateways are also known as IP routers.What is the default gateway? The default gateway means that if a host cannot find an available gateway, it sends the packet to the default designated gateway, which handles the packet. The gateway used by the host is now generally referred to as the default gateway.DNS server:DNSRefers to the domain name server. InThe domain name on the internet is one by one corresponding to the

?The answer is: no repeated data packets are received or sent repeatedly.Why? Right upstairs, every server maintains a route table. The route table determines where data packets should be sent.Why can't I receive repeated data packets?A: The client only sends data to the unique IP address on your server.Why not send data packets repeatedly?A: The route (PATH) for sending data packets is unique.

Thank you! We look forward to your answers. [Question] This is a question about Internet sharing. The Internet access here is of course on the Internet, so an

integrated use of encryption, password, VPN connection or other identity authentication mechanism, the establishment of a multi-level strict security system, which can effectively reduce the IP address conflict brought about by the security threat. To prevent IP address

inconsistent, there is an illegal access behavior. In addition, you can also detect IP address theft from the user's fault report (a message indicating a MAC address conflict occurs when an IP address is being stolen. On this basis, the common prevention mechanisms include:

The IP addresses that have the same access behavior are uniformly divided into the same virtual work subnet, and the relevant routing policies are properly set up, so that we can effectively deny the illegal attackers the ability to steal other work subnet IP
