About the application of routers??? What is a router used for?

It may be laborious to do this, but it may not be really effective. If DHCP is enabled on the router, IPs outside the DHCP address pool can also be accessed by manually setting a fixed IP address.

For example, if you say that the DHCP address pool arrives, it should be 6 IPs, not 5. 5 IPs are 100 to 104. These IPs are DHCP, that is, dynamically assigned.

The IP outside of this address pool is .You can manually set the static IP on the computer or mobile phone to log in to the router to surf the Internet.

Therefore, this method of yours can prevent those who do not understand, and it will not be effective against those who are proficient in this way. However, many people don't know that you can also set a fixed IP manually, so you can be fooled, hehe.

This problem,You think too complicated.,Wireless router set IP binding or something, when the system is reinstalled, there are always many problems.,Just press my router and talk to you.。 Wireless routers have a password setting, and anyone can't get on without your password, unless a very powerful hacker cracks it. You set broadband restrictions mainly to prevent an exception from a computer robbing your network, not to limit yourself, you have to understand this, there is also mobile phone Internet access, directly open the mobile phone wifi to receive the signal, hit the router password to connect.

If the computer is not controlled, it can be automatically assigned IP. If you need to use your own IP address one by one, it is convenient to control the network speed on the router.

The role of the router.

One of the functions of the router is to connect different networks, and the other is to select the route to which the information is transmitted. Choosing a smooth and fast shortcut can greatly improve the communication speed, reduce the communication load of the network system, save the network system resources, and improve the smooth rate of the network system, so that the network system can play a greater role.

From the point of view of filtering network traffic, routers function very similarly to switches and bridges. But unlike switches, which work at the physical layer of the network and physically divide network segments, routers use specialized software protocols to logically divide the entire network. For example, a router that supports the IP protocol can divide the network into multiple subnetwork segments, so that only network traffic destined for a specific IP address can pass through the router.

For each received packet, the router recalculates its check value and writes a new physical address. As a result, using routers** and filtering data tends to be slower than switches that only look at the physical address of the packet. However, for those networks with complex structures, the use of routers can improve the overall efficiency of the network.

Another obvious advantage of routers is that they can automatically filter network broadcasts. In general, the entire installation fail-or-fail process of adding a router to a network is much more complex than a plug-and-play switch. Customer service number 222 will answer for you.
