How to bind MAC and IP address in the network?

For example, my IP address is 00-11-2F-3F-96-88 (how can I see my MAC address?) Enter ipconfig all from the command line, and the response is as follows:

physical address. .00-11-2f-3f-96-88

dhcp enabled. .no

ip address. .

subnet mask .

default gateway .

dns servers .

primary wins server .

This information is the IP address and MAC address of your current computer!

Next, enter on the command line: arp -s 00-11-2f-3f-96-88.

internet address physical address type

00-11-2f-3f-96-88 static

That's it. What if you want to delete it? Typing arp -d from the command line will delete.

Examine. Look at your IP address and the MAC address of your network card. For Windows 98 ME, run "winipcfg", the IP address you see in the dialog box is the IP address, and the "adapter address" is the network card.

MAC address. On Windows 2000 XP, enter "ipconfig all" in the command prompt to display the list.

"physical address" is the MAC address, and "IP address" is the IP address; To bind the two, enter "arp -s IP address mac."

address", e.g. "arp -s 54-44-4b-b7-37-21".

Bindings can be set up in the router.

Because in the command line, use the arp command to untie the old one and then bind the new IP address. This method of leasing is relatively simple, and it can be completed by using the arp command that comes with the system instead of using third-party tools.

When ARP spoofing occurs in the local area network, the ARP virus computer (computer (computer)) will send ARP spoofing broadcasts to the whole network, and other computers (computers (computers)) in the LAN will dynamically update their ARP cache tables.

To record the MAC address of the gateway as the MAC address of the ARP virus computer (computer (computer)), we only need to check the MAC address of the current gateway in other affected computers (computer (computer)).

There are benefits to IP binding with Mac, specifically:

1. MAC binding is an important means of network management, most of the Internet access and flow control strategies are based on IP addresses, and you need to bind IP and MAC to better apply Internet access policies.

2. It can achieve effective Internet records and Internet statistics. If it is not bound, the record statistics cannot be effectively located to specific users.

3. Save IP resources and prevent IP theft.

4. Reduce ARP attacks and eliminate IP address conflicts, thereby improving the stability of the network.

Mac is a personal consumer computer developed by Apple since 1984 with "Macintosh", such as: iMac, Macmini, MacBookAir, MacBookPro, MacBook, MacPro and other computer cores. Using a stand-alone macOS system, the latest macOS series is developed based on the NEXT system and is not compatible.

It is a complete and independent operating system.

It is possible to set access by binding a MAC address and setting it through a router, which can be achieved to a certain extent. Because it depends on whether the router supports the security settings option or not. If the router doesn't support it, you can't do that.

1) Settings page - > DHCP server - > static address assignment - > bind all valid IP addresses to MAC addresses, enter and save them.

2) Settings page - > Security Settings - >Firewall Settings> select Enable Firewall, Enable IP Address Filtering, Turn on MAC Address Filtering - > select All packets that do not meet the set IP address filtering rules are forbidden to access the Internet through this router and only allow MAC addresses that have been enabled in the MAC address list to be set up.

3) Settings page - > security settings - > IP address filtering - > add new entries - > fill in the valid IP address and select to make all entries effective.

4) Settings page - > security settings - > MAC address filtering - > add new entries - > fill in the valid MAC address and select to make all entries effective.

After setting this way, except for the IP and MAC addresses that have been set, everything else is prohibited.

However, it can be accessed normally within the local area network.

arp -s ip mac

You put arp ?, you put arp ?, in the command lineYou can see it.

Since it is said that the IP is bound to the MAC, you must set the IP on the microcomputer, otherwise how to reflect the "binding".

Its function is that once this IP is bound to the MAC address, then the computer can only use this IP in the future, and the same IP can only be used by the bound computer. Convenient network management.

The effect is that this MAC address can only use one IP address.
