How to bind a dynamic IP address to a fixed IP address?

Dynamic IP addresses are random IP addresses that are assigned when needed. Dynamic IP address and static IP address are corresponding, the so-called dynamic means that every time you go online, Telecom will randomly assign an IP address, static refers to the fixed allocation of an IP address, every time you use this address. Because IP address resources are very valuable, the IP addresses used by most users when surfing the Internet are dynamic, just like computers that access the Internet through modem, isdn, adsl, wired broadband, cell broadband, etc., are temporarily randomly assigned an IP address every time they go online.

An IP address is a 32-bit binary number of addresses, and theoretically, there are about 4 billion (2 to the 32nd power) possible address combinations, which seems like a large address space. Actually, according to....

1. Globally**, replace the IP of the whole machine (replace the IP of the entire computer or mobile phone).

2. Partial**, replace the IP of some programs (only change the IP of the window or the IP of the process).

There are millions of hosts on the Internet, and in order to distinguish between them, people assign a special address to each host, called an IP address. Through the IP address, you can access each and every host. An IP address consists of 4 parts of digits, each corresponding to an 8-bit binary number, separated by a decimal point.

The three network information centers of NIC, APNIC, and RIPE are responsible for the allocation of IP addresses in the United States and other regions.

Dynamic IP: Because of the shortage of IP address resources, users who access the Internet through ** dial-up Internet or ordinary broadband Internet access generally do not have a fixed IP address, but are dynamically assigned a temporary IP address by the ISP. Ordinary people generally don't need to know about dynamic IP addresses, these are done automatically by computer systems.

Dynamic IP addresses.

When users access the Internet through dial-up or other means, they are usually assigned a dynamic IP address from the local ISP (Internet Service Provider), so the IP address assigned to the user may be different each time they go online, which is the so-called dynamic IP address block, also known as floating IP.

Static IP address: A static IP address is similar to a fixed IP address as opposed to a dynamic IP address, and is generally assigned to users by the local network management center. Other users can access the host through this IP address.

Shared IP address: For virtual hosts, a shared IP address is a common IP address for any ** on the same host, and users on this host usually cannot simply use the IP address to access their **.

Exclusive IP address: Within the scope of virtual hosting, the exclusive IP address is relative to the shared IP address, that is, a ** independently uses an IP address, which can be directly accessed through the IP address.

For example, if a user applies to a local telecom for an ADSL dedicated line for commercial purposes, then the local telecom can provide the user with a fixed IP address, also known as a physical IP.

Two points: 1To do port mapping (which can be achieved on the router) you also need to install the dynamic mega old domain name client software, it is recommended to make the kernel coarse with peanut shells! **Address available upstairs Lost memory? The address given.

2.If you use the domain name you apply for to point to the address of your intranet mail server and make your own mail server, some mailboxes (such as foreign ones) may not receive the clan upgrade, because your IP address may be blocked by the other party's mail server.

1. Select "Start", click Run, type "cmd" in the run, press Enter to enter the command prompt window.

2. Type ipconfig all in the pop-up cmd command line, find the ipv4 address and write down the physical address.

3. Type the command arp -s ipv4 address value physical address value, so that you can bind the IP.

Because you are an ordinary broadband user, the IP of an ordinary broadband user is randomly assigned by the operator, and every time you connect to the network, after passing the broadband account authentication, the operator's authentication server will randomly assign an IP to your computer, so it is different every time, that is to say, you cannot bind.
