Questions about domain name resolution to IP

Of course, you can, just set the domain name to set a record and resolve it to the IP.

Log in to the control center, domain name management - DNS resolution If you set the IP point - select the IP - fill in the server IP address - click Update - click to restart the NDNS server, you can do it. For example, if you set the cname point to -- select CNAME -- fill in the server alias -- click Update -- click to restart the NDNS server. If you set URL**--select URL** or implicit**-fill in the already accessible address you want to **-click Update--Click Restart NDNS server.

Add a secondary domain name: Fill in the subdomain name in the lower left corner of the subdomain name to be added, click Add, and set the point. Delete a secondary domain:

Select the secondary domain name you want to delete, click Delete, click Update, and click Restart NDNS Server. Generally, it can take effect immediately after making a point, but if your computer has accessed this before, there will be a cache, and it will take two hours before you can officially access it. If you are not sure, you can check it.

Log in to the management interface of your own domain name, there is a record of adding A, fill in the hostname www or leave it blank, and fill in the IP of your space

Then add your domain name binding to the space.

1. Enter the service provider that applied for the domain name**, log in to your own access management center, and click to enter the domain name management. Manage domain names on the domain name list.

2. Modify the DNS of the domain name, the default is the DNS of the domain name service provider, if you want to modify, choose to use custom, and then enter the DNS required by the space provider in the DNS list box, and finally click Confirm to submit.

3. To start domain name resolution, there are several resolution methods of some domain name service providers, and there are two kinds of resolution: convenient resolution and advanced resolution. If it is the first time to use it, then choose convenient resolution, directly enter the IP address or alias of the host server, and confirm the addition.

4. Advanced parsing can also be operated, generally A records and CNAME records.

5. Enter the IP address of the **space (please contact the server service provider to obtain the IP address), click OK, and the DNS will automatically help you create two **resolution records, which can be accessed through and .

The external service needs to be filed for the domain name to be accessed normally, and the server has an address, that is, the IP address of the server, which is a string of numbers, but the number is difficult to remember, the domain name and DNS are born, and the DNS is to correspond to the IP address of ** and **.

When we enter **, it is equivalent to entering the IP address of **, and we can access **. According to Articles 2 and 4 of the Measures for the Administration of Internet Information Services, those who engage in Internet information services within the territory of the People's Republic of China must obtain a license or perform filing procedures.

Otherwise, tremor shall not engage in Internet information services. In this case, it means that the owner of this **** has not applied to the relevant state departments (communication management department) for the record, and the record mainly includes the ICP record and the public security bureau record, which usually refers to the ICP record. The solution is also very simple, ** personnel to apply for and record a new domain name.

For example, I use the 1% off cloud server in the golden autumn cloud season of Little Bird Cloud, then I will file for 0 yuan in Little Bird Cloud, and there will be customer service staff for detailed communication during the filing process, if you don't want to record, you can replace the cloud server with a Hong Kong or overseas node.

**The server is domestic, and the resolved IP must be domestic.

The problem is not with your domain name resolution. Instead, the data that should be returned from the Unicom exit is not communicated from the Unicom port as expected due to the default route or other factors, but from the telecom port.

The whole communication process goes like this:

Because it is a server, the client sends a request to access the server

China Unicom client (China Unicom IP address) -- client gateway (China Unicom) -- dynamic routing protocol, select the shortest path (China Unicom core network) -- server IP (China Unicom address interface).

After receiving the request packet from the IP interface of China Unicom, the server responds with the following message:

Server IP --- Server Gateway (China Unicom) -- Dynamic Routing Protocol, select the shortest path (China Unicom Core Network) -- Client IP (China Unicom).

At present, I think you have doubts about whether the server responds to this section and whether the data can be fed back from the NIC interface of China Unicom IP and back to Netcom. It is recommended that you run the tracert command on the server to trace the route. For example, tracert the IP address of a Unicom client to see whether it goes out through the gateway set by the Unicom network card.

The safest solution is to do 2 PBRs on the routers that are connected to the server

The rest have a default route with the lowest priority.

Generally, if the dynamic routing protocol is activated on the router, it will automatically be transferred to the corresponding network environment.

The server data is all from the gateway of Netcom, not through telecommunications.

Now the multi-line host is the same IP.

1. First of all, we open the computer desktop and click on the bottom left.

Corner start option.

2. Then we find and click on the run option in the pop-up interface.

3. Then a run dialog box will pop up on the computer desktop.

4. We enter the command cmd in the run dialog box and click OK.

5. After clicking OK, the system will pop up a DOS window.

6. We enter the command nslookup+ domain name in the DOS window, and then press the enter key, and the system will forward resolve the domain name.

7. Then the ** interface that pops up in the system will return the required IP address.

All devices that can be connected to the Internet are to find the specified device through the IP address, but the IP address is long and difficult to remember, so for people, the domain name is used instead of the IP address, but the IP address is still used when communicating between machines, and the process of domain name resolution is to convert the memorable domain name into an address that the machine can recognize.

The DNS protocol is used.

To see which IP address the network domain name is currently in use, simply:

1. Enter the DOS interface of the computer, enter cmd in the run, you can enter the DOS interface 2, enter the command in the DOS interface, nslookup domain name 3, and you can see the IP address resolved to the domain name from the result.

4. Since different networks use different DNS (domain name resolution system), if a domain name has multiple servers, it may resolve to different IP addresses under different DNS.

1. Click the computer start menu - run;

2. Enter cmd to enter the DOS interface;

Start-Run-Enter "cmd" enter.

Take Google, for example.

Enter ping enter.

You'll see reply from

From is followed by the IP address.

DNS resolution process and principle.

Step 1: The client makes a DNS request and sends the request to the local name server.

Step 2: When the local nameserver receives the request, it will query the local cache first, and if there is such a record, the local nameserver will directly return the query result.

Step 3: If the local cache does not have the record, the local nameserver sends the request directly to the root nameserver, which then returns the address of the primary nameserver of the queried domain (a subdomain of the root) to the local nameserver.

Step 4: The local server sends a request to the nameserver returned to the previous step, and then the server receiving the request queries its own cache, and if there is no such record, it returns the address of the relevant subordinate nameserver.

Step 5: Repeat step 4 until you find the right record.

It is recommended that you describe the problem clearly, and how to resolve the specific domain name depends on your existing conditions, such as whether there is ** space, which domain name it is, etc. If you really don't know how to parse, it is recommended that you visit the American Host Detective Forum, there will be many people who can help you solve this problem.

There are many kinds of domain name resolution: 1 to do IP change, that is, A record, 2 to do MX record resolution, 3, to do URL**, 4 to do alias resolution.
