I don t have DNS, but I can surf the internet with a slow speed

Probably pulled off by a Trojan with a 360 first aid kit,

The choice of DNS has nothing to do with the speed of the network, but it has to do with the speed of response.

1. The DNS provided by the ISP is certainly the most responsive, but not necessarily the most comprehensive.

2. If you want to open the web page, you must provide as many DNS services as possible.

3. While using the DNS provided by the ISP, it is best to add the public DNS to it, and the address is and.

Yes, the DNS server is slow, and there will be various problems such as lag when playing games or watching dramas, and it will be better to optimize the DNS network speed.

Sometimes the DNS cannot be used or the DNS is abnormal, which will cause the computer to be unable to access the Internet, how to solve it? Below I will explain to you the solution to the problem of DNS and can't go online, I hope you like it!

Open the Run dialog box and enter cmd.

Click OK. <>

Enter ipconfig flushdns.

According to you, it looks like you're a campus network of a certain school.

It stands to reason that you can access the Internet without DNS, and some software that does not use the DNS function can be used, for example, QQ, some of his server addresses are recorded in the software in the form of IP, and it is possible that you can record in the configuration information when you can surf the Internet normally, so you don't need to find the IP through DNS.

By the way, what is DNS, DNS, DomainNameSystem or DomainNameService, i.e. the name Domain Name System. Its role is to translate the domain name interpretation into an IP address. We use domain names that are easy to remember, and computers use IP addresses to search for hosts on the Internet, and there must be a server that converts IP to domain names (reverse) or domain names to IP (forwards).

Please refer to the details for details.

So that's why some software doesn't need to use DNS, because he uses the IP address to access the server directly, so he doesn't need to go through DNS translation.

In addition, because the DNS of each network (mainly refers to the service provider, such as your school should be the management body of the school) is different, it is recommended that you ask the school's network administrator if there is a problem with the DNS server or a change. But generally speaking, it should not be changed often.

1. After the IP is correctly configured, the network can be ensured.

2. DNS is responsible for the resolution of the domain name, if you set the host, you can go directly to the Internet without DNS, but only a few you set in the host.

3. If DNS is empty, it means that DNS is not set, or the DNS address is not obtained when the IP is automatically obtained.

The computer caches DNS for a period of time.

Run cmdipconfig displaydns

You can check it out.

Maybe many friends don't know what DNS is.

To put it very clearly, it is a service that binds IP and domain names.

You can compare DNS to a mobile phone address book, and the process of surfing the Internet to a call, you have to call **to your friends, you have to know the **number, one or two is fine, once you have more friends, you can't remember it;

At this time, the address book is particularly important, record the corresponding name and ** number in the address book, and you can directly dial the name to call in the future;

with"Name"(**) when we"Hit **"(Open**When it's actually openThis IP addressI'll be able to find it for you soonthe nearest convenience store; and take youIt took a long time to find itOr say to you after looking for a long time"Forget it, I don't know. "。

The same,DNS service providers are not the only onesYes, the general broadband operator will give it to youA DNS is automatically assigned, butThe information may not be complete, so you're on the ** when you open itIt took a long time to find itThe corresponding IP address, orNot included at all

Let me point out that changing your DNS won't increase your internet speed, you can use your broadband for as much as you want

Changing the DNS only reduces latency and makes it faster to open web pages.

Well, speaking of which, I believe all of you should have a certain understanding.

Press the Win key (the one to the right of Ctrl) + R at the same time

Enter control and press enter to go to the control panel:

Click on the following to do so:

Right-click"Local connection"click"attributes"：

Click"ipv4", and then select Manually configure DNS to enter it below

The connection latency may vary from place to place, so you can ping it to test the latency

Generally speaking, the lower the DNS look, the faster it will be found, and the faster it will be opened.

Google's DNS service:

It can be said to be one of the most widely used and well-known DNS in the world.

withIt is very popular in the country and

Not only is it fast and stable, but it's also pure and hijacking-free, with no forced ads (I mentioned hijacking by some service providers above), and it has other DNS for different purposes

Secondly, there is also the DNS service of the domestic Internet boss can also be tried, I have tested the latency is very low:

To reset the router, you also need to set it up again (you can go to the guide).

Clean your computer's DNS cache

Start Run Enter: cmd Press Enter, open a Command Prompt window, and then type:

ipconfig flushdns enter the command to rebuild the local dns cache (a prompt will be prompted for a successful refresh).

Mine is the same, call Netcom, they say the router problem, ask to plug the incoming cable directly into the computer. The facts are clearly there, it is the operator who is doing it, he can detect that you are using the router, so there is a problem with the permissions. I think so.

Maybe because you are lazy and never change your router password, this password is public admin when it leaves the factory, and hackers take advantage of your negligence to modify your router's DNS. Please log in to the router immediately, change the DNS in the DHCP parameters, you can set it to and, China Telecom, Ali Security (**) Weibo has said, please refer to it for details.

Sometimes the DNS can not be obtained only through manual settings, sometimes the manual setting of the DNS will cause the problem of not being able to access the Internet, at this time you have to modify the DNS to automatically obtain, the following I will introduce how to obtain the DNS and set it to a fixed DNS. There are two steps, the first step is to get the DNS address, and the second step is to set up the DNS.

Make sure your computer has internet access, if you can't, I'll show you how to know DNS later. Click [Run] in the start menu, or you can directly press the shortcut key win+r to open the running window.

2In the run window, enter cmd and press enter to open the command window.

3. Enter the command ipconfig all in the command window, press the enter key, brush out a bunch of words, and find the IP address behind the [NDS server].

4. If you can't connect to the Internet now, you can call ** to your network service provider to consult, the network service provider is who you pay the network fee to, and he is responsible for telling you the address of the DNS server.

Tap Network on the taskbar to open the Network & Sharing Center.

In the navigation bar, find the Change adapter settings option and turn it on.

Right-click the network you want to set up DNS for, and then select Properties from the context menu that opens

In the Properties panel, select IP4 and click Properties below

In the properties panel, switch to General Options, check [Use DNS Server Address Below], enter the DNS address you got above, and then click the OK button to complete the setup.

Free DNS is recommended: domestic use is recommended).

Google DNS: Foreign).

See Step 2 for the setup method.
