DNS server latency problem, how to solve the high DNS latency buddy

DNS latency doesn't affect anything, that's for domain name resolution, you have to go online, enter an example.

The computer will access the DNS server to find the IP address of this domain name, according to the IP access, just use this once, and after accessing the DNS once, the computer will cache the last application record locally, and then access the same domain name without asking the DNS server.

In short, if you play games, it doesn't have much to do with the DNS server, and it mainly depends on the latency of your computer to the local gateway.

To put it bluntly, if you play the game and access the server directly through the IP, there is nothing to do with DNS, you don't go through that line at all, and you don't need the process of domain name resolution.

Even if you use domain name resolution, you only need to use the DNS server communication when you enter the server for the first time, and then until you restart, your computer will get the domain name resolution information from the local cache, and you don't need to access DNS.

So don't worry about DNS latency, that's.

Brother, let me tell you this, the DNS delay of the same bandwidth optical fiber is only 1-2ms. It is normal to use ADSL to access the Internet with a latency of 43. If you play Hotblood Cards, it's probably a problem with the game server.

You can't change this thing, you have to change it to telecom and complain about them too slowly.

First check what specific software and what port is sending packages out, and then block the port and close the software.

Just open your game, it will be better!

Ali alidns:baidudns：The DNS latency in foreign countries is very large, basically ranging from 30ms to 400ms.

The nearest latency in China can be about 3ms, about 6ms is good, and the delay of a little farther away is between 10 and 30ms.

In the data output by ping, time represents the time taken for an ICMP packet of the ping to be transmitted to the target machine and back, and the higher the time value, the more time it takes to resolve the domain name when you access the network.

InFor example, the DNS server may be in Hangzhou, and the address you are connected to the network is also in Hangzhou, so the latency may be small. If the DNS server is in the United States, and the location where you access the network is far away from the United States, the latency may be large, after all, there may be many nodes in the middle. Of course, the time closest to you is not necessarily the smallest, just like if you go from Shanghai to Beijing, I go from Paris to Beijing, you go by bicycle, I fly a fighter jet, who do you say is more big?

Access to the network can be similar, with good and bad physical circuits and congestion between different nodes...Wait a minute. The choice of DNS should not only consider latency.

For example, some DNS servers may plant you with advertising messages or parse errors. Reference.

The ping DNS latency is normal if it is less than 80ms and will not be perceived. Your network card is not necessarily a DNS issue.

You try whether the DNS in the picture below is all card, if all are card, it is another problem. For example, ping your router to see how much latency is, ping your public IP to see how much latency is, etc. Dude. I.

Wave your hand. Even me.

I don't hit either! In terms of mobile phone acceleration, Tencent Mobile Manager took the lead in launching the desktop launch "small rocket" to accelerate the mobile phone, which greatly enhanced everyone's enthusiasm for mobile phone acceleration, so that the mobile phone security software is no longer so boring, and it is more interesting. And this innovation is also imitated by other peers, although it is not a rocket launch, but it also follows the direction of mobile phone acceleration and fun.

1. When upgrading the DX, overwrite and install some important files under the system.

2. Check whether the wiring in the case is loose, whether the hard disk interface, etc., as well as the graphics card, network card, sound card, memory, etc. are plugged in tightly.

Third, the power supply problem. Due to the unstable voltage of the inferior power supply, it is very likely to cause a series of problems, such as crashes for no reason.

Reboot blue screen and other phenomena, power problems cause blue screen mainly because the voltage is unstable, the boot time is too long, and some pulse resistors are formed in a series of devices such as the graphics card, and the computer will find errors when the computer is shut down, so it causes a blue screen!

Hello If there is only a B-pillar, it means that there is a problem with the chassis part, and it is recommended that you go to see if the chassis part is loose, because the B-pillar is a part that does not indicate that it can make abnormal noise.

blob file to the desktop, just cut the clientregistry in the steam installation folder There are two solutions to this situation, one is that your computer is not connected to the Internet of Things or is restricted by the firewall Steam network connection, and the other is if the network is normal, then log in to Steam.

First of all, it is necessary to clarify what type of latency the server has, and here are a few examples of latency.

1.For example, if the application deployed on the server is slow and the user accesses it slowly, and feels that there is a delay, you need to check whether the server's resource usage, io, CPU, and memory usage are normal, and if the resource usage is as high as 80% or more, you need to consider optimizing the application or expanding the capacity.

2.If the time of the server lags behind the normal time, you need to deploy the NTP time synchronization service to synchronize the time.

3.If there is a network delay, the network card traffic of the server is full, resulting in the network delay rolling delay of the access server, at this time, you need to check what will occupy the network card traffic the most, so that it can be optimized, if it cannot be optimized, you need to use the hand to expand the network card, or the server to expand.

DNS refers to the domain name resolution server, simply put, every time you open a web page, the DNS server needs to be normal. The DNS server address for each region (usually province) is fixed (configured by the carrier). This address usually cannot be changed indiscriminately, and the wrong setting will cause the web page to be unable to open.

Usually with automatic fetching. Manual setup is not recommended. There are usually two DNS servers: primary and standby.

The active is hung up before switching to the standby. This is basically not a concern for ordinary users. In short, it is not recommended for individual users to change DNS.

Unless your finished game is a browser game, the DNS settings are directly related to your game. Other non-web games, unrelated.

Game latency is complicated. It has to do with your access network, game server-side network, and many other factors. For regular users, if you want to reduce the lag of the game.

I recommend. First, check whether the network you access is better, simple principle: install Netcom broadband in the north, install telecom broadband in the south, and install optical fiber FTTH as much as possible if you can install optical fiber, and the bandwidth is as high as possible.

If the broadband you install is not a mainstream operator, it is recommended to replace it according to the above principles.

Of course it's useful, it's useless to modify it yourself, and the DNS acceleration of the accelerator company** is very useful.

Try this, it works for yourself:

The latency of normal ping of telecom DNS is about 100 milliseconds.

Ping DNS servers is not available for meaningful data, and some NDS servers have set up a ban on ping.

Start Menu - > Run - > Enter the IP address of the DNS you want to see the delay in the space; Format"Ping space + DNS IP address"(without quotation marks) is an example"ping "After that, a black box will pop up, "You can see the delay", time=100ms, indicating that the delay is 100 milliseconds.

start menu -> run ->cmd->ping ; You can see the latency from the original address to the address.

If you don't open any web page, the DNS of the ping should be within 40ms, which is normal, and if it is exceeded, it is not normal.

Hello, Anhui Telecom will answer for you.

Hopefully, the following will be helpful to you.

You can directly log in to Anhui Telecom's online business hall to test the network speed and status, ping DNS servers cannot get meaningful data, and some NDS servers are also set to prohibit ping.

Anhui Telecom 159**4m free liter 8m, three-machine version free liter 12m! There is also a 100m optical fiber ** activity, the lowest** only 189 yuan!

If your question is solved, please give a "satisfactory answer", and if you still have questions, please continue to ask. Have a nice day, thank you!

Generally within 20.

Network latency means that the network response time is slow. DNS latency means that data is passed through DNS at a slow rate.

1. Different ways of data transmission.

2. DNS delay: The DNS system responds to the user's query by recursive query request, providing key basic services for the operation of the Internet.

Second, the impact is different.

1. Network latency: The higher the network delay, the slower the network speed, and the value of network delay 1 represents 1 millisecond. The smaller the jitter of network latency and network latency, the better the quality of the network.

Third, the characteristics are different.

1. Network delay: The client and server are directly connected through a router, but the bandwidth is only 10kbps, but there are multiple applications at the same time that need to transmit 200kbps of data that far exceeds the bandwidth, which will cause a large amount of data loss, which is manifested as response delay.

2. DNS delay: DNS packets will not be intercepted, so a concealed channel can be established based on the DNS protocol, so as to smoothly pass through the firewall and transmit data between the client and the server.

First of all, it is normal for the network camera to have a delay, but it is just a matter of how much time is delayed. In general, it is normal for different manufacturers and different solutions to have a delay between seconds. Secondly, if the delay time is too long, generally more than 2 seconds, it may be related to the network architecture, such as switches, network cables, etc.

Third, if the same network, different display methods, and different latency are different, it may be related to the processing power of the display host.

Judging from the subject's **,It may be 10M bandwidth,Envy me,Internet speed and DNS only have a little to do with it.,As long as there is a DNS cache, it doesn't matter much.。

DNS server:

Choice: You can ping, the smaller the latency, the better, you can also find a software (such as pinginfoview) to batch ping to see which one is better.

Setting: NIC -- > right-click attribute -- ipv4 -- > fill in the DNS server -- > OK.
