DNS is a directory used to match an IP address and domain names. As you know, every site ever created has its own. Basically, you can access any site by inserting its IP into the browser’s address bar. Since they are pretty hard to recall, domain names are used instead of them. People are not aware of just how crucial DNS really is.
It wouldn’t be possible without it. But it is too much to understand for most people. The issues associated with DNS can give you quite a lot of headaches. These occur even when you have experienced them when you do a little bit of hosting. The reason being that there are countless possibilities. Finding the proper solution for the issue you are facing can require so much time.
Naturally, the first thing that comes to anybody’s mind is that you need to try out and find what is the exact issue. You can do it by performing a troubleshoot. In case you are interested in learning how to troubleshoot DNS, be sure to take a look at constellix.com. Now, we would like to provide you with the commonest DNS difficulties, and what you can do to solve them. Without further ado, let’s take a look at these.
1. High TTL Values
TTL is short for time to live. When TTL gets high values, chances are that it will affect your website in terms of having a high wait time. Plus, you can expect the website to experience a stoppage when moving traffic among a couple of different servers. Of course, we are talking about a pretty irritating problem that can give you a lot of headaches before you can reach a solution.
Thankfully, this is not something that will take a long time before you can make it right, once you know this is an issue. You can do this by lowering these values in your records. Of course, you need to make sure that you don’t overdo it. If you do, you can expect to deal with a high query load issue. But, if the server you have can handle the extra load, you will have no problem with maintaining it.
2. Hardware/Network Failures
Without any doubt, the highest percentage of issue s associated with DNS can be contributed to network failure. We know it sounds pretty strange to some people, but some of the problems can be related to hardware failure. Sometimes, these problems can be completely out of your control. So, you can spend quite a lot of time before you can find a proper solution.
When we say that, we speak both for hardware and network failures. The first thing you need to do is to troubleshoot the hardware/network configuration settings. That way, you will be able to locate the source of the issue. Naturally, you will need to know how to perform it efficiently. Therefore, you should do a little bit of research on how you can do that. In most cases, you will find out that the problem is related to configuration problems.
3. Inappropriately Configured Records
Most of the time, any issues you experience with DNS will be related to the records. Certainly, this is the biggest source of problems. In case you don’t do a good job in inserting a proper IP address and good values in the records, you will have a big issue in your hands. Just in case, you should check all the records, like DKIM, SPF, and MX. They are crucial for receiving a proper email delivery.
The best way you can overcome these problems is to try and locate the issue. Let’s say that you have problems with email delivery, you should take a look at those records we’ve already mentioned. If you find out that issues lie somewhere else, you should pay attention to the ones who are responsible for that part of the records. Narrowing down these options will lead you a long way, you can be sure of that.
4. High Latency
Now we would like to discuss the issues that cause high loading, which can be pretty problematic. We are talking about high latency. It can occur as a result of name servers not being in close geographic closeness in the highest percentage when it comes to the users who are visiting the site in question. The other possible problem can be related to network congestion.
When it comes to a solution to this problem, it depends on where it is. From our experience, we can say that changing these that are close to the user’s location is something that will work. We are talking about a proven method, believe us. In case it doesn’t, be sure to retrace any configs you have made before the emerge of high latency. Surely, these are two only options you can choose from, and one of them is bound to provide you with a solution.
5. DDOS Attacks
DDOS attacks can be easily described as one of the biggest issues you can experience with DNS. For you to be able to solve this one, you will need to have the most efficient security software you can come across. Thankfully, there are a lot of different solutions you can choose from, and without a doubt, some of them are effective. As you can see from their name, they are caused by malware attacks.
These attacks will drove the highest possible traffic to your site, and overwhelm it with it. At some moment, the site will completely crash. So, now you understand why is it so important for you to have software that can provide you with the highest possible level of security. Furthermore, you should use DDOS’s mitigation device. That way, you will be able to avoid all the dangers.
Summing Up
As you can see from this article of ours, when solving DNS-related problems, you will need to locate the source. After that, you will be able to act. Here, we’ve provided you with the commonest ones and how you can come across a solution.
