DNS how does it work?
What is DNS? This abbreviation stands for Domain Name System. The DNS protocol converts the name of a website into numerical data. Such resources are understandable for the computer, so the web page starts to be displayed in the browser. The DNS server simply looks up a website’s IP address based on what the user has typed in their browser.
DNS records—what are they for?
By DNS records, we mean a number of rules that allow you to configure adomain. They are what are used to “translate” the name of the website into an IP address. DNS records consist of several elements, which are:
- name
- type
- TTL
- priority
- value
Many people involved in creating and optimizing websites – especially SEO specialists – wonder if DNS can affect Google andpositioning. It turns out that it is. If the DNS servers are slow, they will take longer to load your site. Ultimately, yourwebsitemay lose visibility in organic search results because resource loading speed is a ranking factor for Google. Also, possible interruptions and difficulties related to the operation of DNS servers may have a negative impact onSEO.
What is DNS in practice?
In practice, it’s easy to introduce what DNS is. When you use a search engine as a user, after entering the URL in the appropriate field, the software establishes communication with the local server. Thebrowserthen asks you to convert the domain name to an IP address. There are 13 root-servers available worldwide. Local servers send their queries to them. As part of the response, they receive an IP address assigned to a given domain. The browser opens it and the user sees the website on the screen. While the whole thing sounds like a long process, it takes a very short time. In short, thanks to DNS, the browser knows which IP address is assigned to a specific domain name.
DNS server – what is it?
Two organizations are in charge of DNS servers. It’s IANA and ICANN. However, it is worth bearing in mind that these institutions are not responsible for the sale and purchase of domains. Their task is to take care of the order and efficiency of DNS servers. Thanks to them, websites can load quickly, efficiently converting a domain name to an IP address.
DNS server is not responding
What to do when DNS server is not responding? This problem usually arises for two reasons. The first is DNS server errors with your ISP. The second, however, may be a problem with the DNS client service on the computer. If the ISP has not noticed any problems on its side, verify the operation of your equipment. Run the DNS client – in Windows, just type the command: services.msc. Then find the “DNS Client” option and check if it is enabled. You can also restart it.
DNS – how to set
It is a good idea to consult a specialist, such as your ISP, for setting the DNS server. You can direct your computer to addresses such as:
- Google: 8.8.8.8 and 8.8.4.4
- Cisco OpenDNS: 208.67.222.222 and 208.67.220.220
- Quad9: 9.9.9.9
However, it is difficult to say whether they will be the optimal solution in your case, guaranteeing efficiency.
How to change DNS
If the DNS server is not responding and the client is properly configured on your device, you can try to manually change the address in your network settings by entering the address of your choice. It is worth consulting such a change with your Internet Service Provider. Using certain DNS addresses will slow down your network connection, which will negatively affect your comfort.
How to check the DNS of a network
To check a website’s DNS, use free tools such as DNS Checker. Then the tool will present the information available in its database. Using the DNS checker software is simple. In addition, the application shows the addresses of public IPv4 and IPv6 servers.
