The school computer always has to change its IP address in order to access the Internet

It may be a problem with the school's server settings.,The general school teacher machine also has a restore wizard.,Uninstall the restore wizard.,And then fix the IP address with one.,The settings of each computer room are different.,Mainly depends on how the school is designed!

Start-Run, Input.

cmd to open the command prompt, enter "ipconfigall" (excluding double quotes) in the command prompt, and the "physicaladdress" in the display list is the mac address, "ip."

address" is the IP address; To bind the two, enter the "arpsip address."

MAC address", such as "ARPS."

54-44-4b-b7-37-21".

Maybe you are at home with ADSL broadband Internet access and automatically obtains IP, but the school router does not have DHCP service turned on and cannot automatically obtain IP, so you must set a static IP, which is normal. If the school opens the DHCP service, it is inconvenient to manage it in a unified manner, I used to do the network management of the unit, at that time the IP and MAC address were bound, and each computer must use the IP I specified to access the Internet, so that the entire network can be effectively managed.

It is possible that the IP address of the Internet is controlled on the router, so if you want to access the Internet, you must be an IP that can access the Internet, and no other IP can be accessed! But you can connect to a local area network!

However, you can use ** software on a machine with Internet access! Add the IP that can't access the Internet, and then modify the IE attribute on the computer you use to have a connection LAN settings, use the **server, and you're good to go!!

Isn't your school's IP automatically assigned?

Can't I access the Internet if I choose to automatically assign an IP?

If it is a fixed IP, you should not configure it every time.

The situation you are talking about can be divided into two types:

1.You can enter any address in the IP segment to access the Internet;

2.You can only access the Internet by entering a specific IP address.

Implementation: 1In the router's settings, you can disable the DHCP server.

DHCP server" is enabled, and each device connected to this router will automatically obtain an IP address, and will not conflict with other computers, and will be able to access the Internet.

If the DHCP server is disabled, the router will not actively assign an IP address to the device connected to the router, and the device will not be able to access the Internet. You can only access the Internet if you manually set the correct IP address (do not conflict with the IP address of other devices) and the gateway.

2.ARP bindings are set on the router.

After <> binding, your device can only use a unique IP address to access the Internet, otherwise it cannot access the Internet.

Set a fixed IP address and you're good to go.
