There are two types of router mac binding IP types, static and unique, what is the difference?

The binding of MAC address and IP address in DHCP in router is to statically assign an IP address in the IP address pool to a computer with a MAC address, which is generally used on printers and intranet servers that need a fixed IP address.

The static IP address is to directly enter the static IP address and other parameters on the computer's network card, generally speaking, the DHCP service of the router should be turned off at this time, otherwise it may cause conflicts and is unnecessary;

Both of these are static IP address assignments, but one is entered on the computer and the other is bound on the router.

Bind an IP address to a MAC address

For example, bind a MAC address to enable DHCP

The IP of 100 will only be assigned to the bound Mac

Static, DHCP will assign this MAC. It can also be assigned to him to other IPs. One more feature, which can be bound to multiple Macs, or Macs can be bound to multiple IPs

Uniquely, DHCP will only assign this MAC at this time, and the difference is that static can only bind one MAC

If there are not many machines, you can set them all manually, and there will be no conflicts.

If you have a lot of machines, you can set them all to "Auto Acquisition" and turn on the DHCP service on your router.

If an IP address is assigned, the DHCP service will know that if there is a record, it will not assign a duplicate IP to the second host, so there will be no conflict - unless someone else changes the "automatic acquisition" to a manual setting. However, if only one person manually sets a static IP, then the DHCP server will also know that the static IP is already on the network and will not assign it to anyone else, so there will be no conflict. The only possibility of conflict is that a person has manually set up an IP that has been seized on the network and has been arrested.

IP and MAC address binding is a type of static address allocation;

The IP address and MAC address can also be used at the same time as DHCP, the bound IP address is a fixed IP address, and the IP address is assigned by DHCP if it is not bound.

1.The binding of MAC address and IP address in DHCP in router is to statically assign an IP address in the IP address pool to a computer with a MAC address, which is generally used on printers and intranet servers that need a fixed IP address.

2.The static IP address is to directly enter the static IP address and other parameters on the computer's network card, generally speaking, the DHCP service of the router should be turned off at this time, otherwise it may cause conflicts and is unnecessary;

3.Both of these are static IP address assignments, but one is entered on the computer and the other is bound on the router.

The normal binding is to record the IP address corresponding to the MAC address of the computer in the LAN on the router, and establish a correspondence relationship, which will not be deceived by ARP, resulting in the inability to communicate normally. Computers that do not bind their IP addresses to MAC addresses may be vulnerable to ARP attacks. If the computer changes its IP address, the router can still perform automatic learning of the ARP mapping table, and scan the computer for new correspondence, and the computer can still communicate with the router.

Forced binding is to carry out data communication by adding the relationship between IP and MAC, there is no ability to automatically learn ARP mapping table, and if there is no correspondence between computer IP and MAC, the computer is unable to communicate with the router. Therefore, after setting the mandatory binding, the computer that newly connects to the router cannot communicate without adding the correspondence between IP and MAC addresses. Or the computer under the router has changed its IP address, resulting in inconsistency with the IP and MAC correspondence recorded on the router, and communication cannot be carried out.

The functions of routers on the market are similar, take TP-Link as an example to explain:

1.If you need to configure a static IP address in a wireless router, you only need to go to the router settings page, click "DHCP Server", select "Static Address Reservation", and then click "Add New Entry" to enter the specified IP address and MAC address to achieve the static IP setting.

2.If you want to prohibit other devices from accessing the Internet, click "Wireless Settings" and select "Wireless MAC Address Filtering", after entering, confirm that the filter rule has been selected "Prohibit MAC addresses that are valid in the list from accessing this wireless network", then click "Add New Entry" to enter the MAC address you want to disable, and finally click "Enable Filtering".

Disable DHCP, configure a fixed IP, and then bind the IP and MAC.

Go into the router, turn on the firewall, and then Mac filtering will do.

You can ban it with Mac, add a new entry in Wireless Settings - MAC Address Filtering - Add a new entry, write the MAC address that is not prohibited, select Prohibit, and enable the setting.

1.Connect the broadband cable directly to the computer, write down the IP address, subnet mask, default gateway, and DNS server address of the local connection of the computer, and change it to "automatically obtain IP address", "automatically obtain DNS server address" -- OK, and click OK in the dialog box of "Properties" of the local connection.

2.Connect the broadband line to the routing WAN port, and use a network cable, one end to the computer and the other end to the routing 1 2 3 interface.

3.Open your computer browser and enter the router settings interface in the ** bar.

Click "Advanced Settings" on the home page, click "Internet Settings", select "Static IP", enter the IP address, subnet mask, default gateway, DNS server, and click OK.

4.Click on the system status, and the WAN port status shows that it is connected, see if you can access the Internet.

Click OK at the beginning of 35. (When cloning, you need to take a network cable to connect the computer to any one of the router 1 2 3 interfaces, do not connect the wireless signal of the router route).

6.After cloning, click on System Tools - Restart Router.

If you still can't access the Internet, click Advanced Settings - LAN Port Settings, change the default to a try.

You need to find out the MAC address of your wireless router. Then let the higher-level router bind the static IP to the MAC address of your wireless router, and after processing, set the WAN port of your wireless router to a static IP, and turn on the DHCP function of the router. Set the router's LAN gateway to or something else, and you're done.

Next, just connect to the router in the way you usually know and you can share the Internet.

Connect the incoming cable to the WLAN port of the wireless router, configure the wireless router Internet mode to static IP, fill in your IP information, configure the wireless router intranet network segment is not equal to, and enable DHCP

Connect the broadband line (previously connected to the computer) to the WAN port of the router, connect the desktop to any interface of the router LAN, and connect the laptop and mobile phone to the wireless network;

After entering the management interface, click Network Parameters>> WAN port settings, select WAN port connection type as static IP, fill in IP address, subnet mask, gateway, DNS and other addresses, and click Save;

If you know that the broadband has been bound to the MAC address and static IP of the computer, you need to clone the MAC address of the computer on the WAN port of the router to let the router "disguise" as the computer smoothly surf the Internet. The way to clone a MAC address is to connect the computer that was directly connected to broadband Internet access to the RAN port with a network cable.

Log in to the management interface, in Network Parameters 'Mac Address Clone', click Clone MAC Address, make sure that the two MAC addresses are the same, and then save and restart.

A router (also known as a pathfinder) is a computer network device that can transmit data packets through a network to a destination (selecting the transmission path of data), a process called routing. A router is a device that connects two or more separate networks, and routing works at the third layer of the OSI model, the network layer, such as the Internet Protocol (IP) layer.

The dynamic IP is automatically assigned by the router, and the static is set by yourself on the machine, of course, it can also be used when you move it down, if the static is set, turn off DHCP,

At home, you can ask if anyone is using the Internet Law Enforcement Officer, I don't think so, it should be a computer that has been poisoned, and at present, you should find out this computer first, and then kill the system after the virus, and you can settle it.

Register the Mac of four computers, and when there is an attack, you can determine which Mac is poisoned.
