Can I set the IP address area, and what are the precautions for IP address setting?

It is recommended to set a fixed IP

The MAC address of the network card is usually the only one determined, and a table corresponding to the IP address and the MAC address is established in the router, and only the legally registered machine corresponding to the IP-MAC address can get the correct ARP response, so as to control the IP-MAC mismatched host to communicate with the outside world, so as to prevent the theft of the IP address.

Router(config) arp arpa summary: The use of MAC address and IP address can effectively prevent IP address theft, although it is more troublesome to collect the user's MAC address in the early stage, but the establishment of such a mechanism can bring a lot of convenience to the user when managing the network. Therefore, we should collect the MAC address information of the machines in the LAN at the beginning of the network construction, so as to bring convenience to our future network management work!

Hope it solves your problem.

IP address has nothing to do with network speed, whether your network is used by yourself or shared with others with a network cable, if it is shared, it may be someone else's ** or use software that accounts for network speed (such as Thunderbolt, pps, etc.) %d%a

There are two types of IP address setting rules: network address rules and host address rules.

1. Network address rules.

The address must be unique. The network ID cannot start with the number 127. In a Class A address, the number 127 is reserved for an internal loopback function (for loop testing).

The first byte of the network ID cannot be 255. The number 255 serves as the broadcast address. The first byte of the network identifier cannot be "0", and "cavity year 0" indicates that the address is localhost and cannot be transmitted.

2. Host address rules.

Host identities must be unique within the same network. If all digits are "1", the address of the host is the broadcast address, not the address of the host. If all bits are "0", it means "only this network", and there are no hosts on this network.
