How to fix the IP address of a dynamic domain name and how to bind a dynamic IP to a domain name?

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....

Are you mistaken? Any domain name can be bound to a fixed IP, and the so-called dynamic domain name is just a transit server that makes the traditional need to wait for the time to change the domain name to take effect immediately. For the landlord who has a fixed IP, you can use the domain name ** business to point to.

PS: Generally, the domain name ** business promises to point to a new IP within a day

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.

When binding the IP to the domain name, it can be bound through a dynamic domain name system such as Peanut Shell (which is generally available on routers), which automatically binds the obtained WAN IP to the set domain name, and at the same time needs to specify the private IP or intranet hostname. Some routing software also needs to do port mapping.

This should be achieved using **ip software.

You can install a rabbit IP converter, there are two kinds of dynamic and static lines, you can switch the IP address at will, and you can also set a timing switch.

The following steps are performed on dynamic DNS resolution.

Apply for a dynamic domain name resolution service and get a second-level domain name after registration; Manage your own domain name: Go to the domain name mydns resolution management interface, and add an alias to the domain name to the second-level domain name obtained in step 1.

Security has also been greatly improved, and the security of professional web hosting is definitely much higher than that of self-organized servers; On the other hand, as security issues have been resolved, the limitations of web hosting capabilities have gradually been reduced to the extent that they almost do not affect user use at all.

The function of dynamic domain name resolution is to resolve the domain name to the local public IP in real time, and when the public IP changes, the resolved IP also changes in real time, so as not to affect the application of the domain name. Log in to the Domain Name Resolution List on the client and add a domain name resolution list.

Set Resolution Type to Dynamic DNS Resolution. Domain name**Use your own domain name, or a custom second-level domain name prompted.

After you add dynamic domain name resolution, you can view the real-time DNS records and the local public IP monitoring records.

The computer network is modified to a static IP method, and the computer network card IP is set to a fixed static IP address.

Generally, ADSL Internet access is a dynamic IP

If you want to set it to a fixed IP

You can set it to a private address such as:

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. Each host can be accessed through the IP address.

internet

The IP address is defined by the NIC (Internet

network

information

center) is responsible for the planning and management of global addresses; At the same time by inter

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.

Public address (public

address) by inter

nic（internet

Internet Information Centre). These IP addresses are assigned and credited to the registration and to the inter

The organization by which the NIC is making the request. Direct access to the Internet through it.

Private address (private

address) is a non-registered address that is intended for internal use within an organization.

The following is a list of retained internal private addresses. Class A.

Category B. Category C.

and localhost both represent the local network The public address viewed with ipconfig also represents the local network, so no matter which one you enter on your own computer, you can succeed.

In addition, you use XP to do ** release, in fact, XP's IIS does not support external release, he can just give you the local test use, even if you are on other machines on the intranet, you can't open the site published on your machine.

It is recommended to install server2003 on a virtual machine and then publish the site, which can be accessed through the public IP.

It's a small problem, it's so complicated, hey.

No, my computer level is rubbish.

The firewall does not set up access for other hosts.

Do you use a fixed domain name?

1. If you don't shut down, you may change the IP, and the IP address may be forced to go offline and reconnect if there is a lease period.

2. The peanut shell is the client, the software detects your current IP address, reports to the server, and the server then changes your **IP in the domain name server to the one reported by the software according to your records.

3. Home fiber is also dynamic.

4. The fixed IP is different according to the operator, a fixed IP needs to pay 20-150 yuan more per month, consult the operator.

5. Peanut shells free is unstable. It's okay to pay stably with peanut shells. Cheaper than a fixed IP, but slower.

Choice: The steel wire is only tensile and bending-resistant! That soft plastic wire is the optical fiber.

Steel wire + sheath + optical fiber form optical cable! The small box is the terminal box of the cross-optical cable, the yellow one is the pigtail, and the inside is the optical fiber + nylon tensile rope, which is suitable for soft wiring. The big cat is a photoelectric transceiver that converts the optical signal into an electrical signal for the network cable.

1. China Telecom Unicom will remove the wire once at a regular interval, such as 24 hours or 48 hours.

2. It is not clear what principle is used for peanut shells.

3. Home fiber is the transmission layer, and IP is the network layer, two different things.

4. Fixed IP broadband depends on where your access point is, the aggregation layer and core layer are different. And it's different for each region.

10M core layer access, Beijing nearly 10W years.

5. If you want to be stable and want to use a stable product, are you a fool who rents a fixed IP line?

Optional question: The optical fiber looks like a black thick cable with a diameter of about 1 centimeter. You're talking about pigtails, the last segment of optical fiber splicing that is connected to the optical device.

Domain name resolution on the Internet is generally static, that is, the IP address corresponding to a domain name is static and unchanged for a long time. That is to say, if you want to set up a ** on the Internet, you need to have a fixed IP address.

The function of dynamic domain name is to realize the resolution between fixed domain name and dynamic IP address. Every time a user gets a new IP address on the Internet, the dynamic domain name software installed on the user's computer will send this IP address to the dynamic domain name resolution server to update the domain name resolution database. When someone else on the Internet wants to access the domain name, the dynamic DNS server will return the correct IP address to him.

Because the IP address assigned to the vast majority of Internet users when surfing the Internet is dynamic, it is impossible for users to make their Internet computers into a fixed domain name with traditional static domain name resolution methods. And with a dynamic domain name, that dream can come true. Users can apply for a domain name, use the dynamic domain name resolution service, and bind the domain name with their own Internet computer, so that they can build their own ** at home or in the company, which is very convenient.

If you want to use a dynamic domain name, go to learn about peanut shells, which is not recommended.

If you use meibu, it is much more stable than peanut shells, and it will not break often.
