What is DNS, Function and Usage Propagation

What is DNS? DNS is a system that converts website URLs to IP address. Without DNS, you have to type the full IP address when you want to visit certain websites on the internet. Those of you who are curious as to what the details of this information are like, don’t move. Because in this article we will discuss all of them.

Understanding DNS
What is a DNS server? As mentioned earlier, Domain Name Server or what is familiarly called DNS is a system that connects the Uniform Resource Locator (URL) and IP Address. Normally, for internet access or certain websites, users must type in the address ID of the intended website. If not, he cannot enter the desired website.

Because this means you need a complete list of addresses from the website you want to visit and enter them by typing them manually. DNS itself is a special system that ranks our work. Now you only need to remember the name of the domain and enter it into the address bar only to visit a website.

Domain Name SystemDNS is made the domain translator and connects it to the IP address that is understood by the computer. For example, you want access to Google, you don’t need access via 172.217.0.142 in the address bar. But you only need to enter the google.com address. Of course this is very easy for your job.

DNS function
What is DNS management? This is a special feature that functions to make it easier to set up and also manage the required DNS records. By using these DNS records, users can point the DNS server from the domain directly. This makes you who already have a separate domain and hosting don’t need to worry. As the top 5 hosting providers in Indonesia, Qwords.com also provides this feature for its users.

You can directly direct the DNS that you have earlier through the client area and also the DNS settings in the hosting. There are at least several types of DNS records that you should know before using them. A, AAA, CNAME, MX Record, TXT Record, SRV Record, NS record is one type of record that is widely used.

After knowing what DNS is, you should also know how important DNS is. The DNS server is part of the database server that stores all IP addresses that are used to assign hostnames to a particular website. So when you type in Google.com, this DNS server will immediately translate to the IP address and connect you to the Google you want to access.

Finally, you can display Google search as needed. To carry out its duties, DNS itself requires a client program called a resolver to connect the server computer to the DNS server. The resolver program is a web browser and also a mail client. So to use a DNS server, you must install a browser program that becomes a mail client.

Broadly speaking, here’s how the DNS server works:

  1. The DNS resolver will perform the host address in the HOSTS file. When the host address has been searched and found and given, the process is complete.
  2. The DNS resolver looks for cached data that the resolver creates for storing the results of previous requests. If it does, the data is stored in the data cache and then the results are given.
  3. The DNS resolver looks for the first user-defined DNS server address
  4. The DNS server assigns to look for the domain as well as the cache
  5. If the domain the DNS server is looking for does not exist, the search is carried out by looking at the zone file on the server
  6. If it turns out that the data is still not found, the search is carried out by calling another DNS server that is related to the server in question.

DNS Propagation
In the DNS system there is what is called the DNS propagation name. There are many cases encountered when ordering a domain and cannot access the domain when the service is active. This is what is meant by DNS propagation itself. DNS propagation is the time to connect domains to connect via servers.

What is the DNS propagation period? For the time, it was varied and varied because it was determined by the domain used. Generally, the time usually lasts up to 24 hours. If the domain has passed this period of proposition, the domain can be used and can be directly accessed as desired.

There are many factors that determine DNS propagation, including:

  • With an aging domain name, a new domain generally takes time for DNS propagation.
  • Internet server provider, this DNS propagation time is also influenced by the ISP used by the user. IPS adjusts to the new DNS to activate this condition.
  • Registrar: where you can register your domain also affects the speed at which you have DNS propagation.
  • Domains with international names or TLDs generally respond quickly when registering a local domain or ccTLD.

DNS server propagation does take time but you can use tips and tricks to speed things up. There are many ways to speed up this DNS propagation process. the following methods can be used:

  1. Do a refresh first on the browser used. You can refresh this by pressing CTRL + F5 or command + R (for macbook users). You can do it simultaneously and do it continuously.
  2. Perform cache steps on the browser. This can be adjusted according to the browser used. Google Chrome users, click and select More Tools and then click Clear Browsing Data. Meanwhile, Mozilla Firefox users, you can select the Tools menu and then Clear Private Data. Check the Cache option and click the clear private Data Now button.
  3. Disconnect the internet connection for a while. This was done in order to speed up the ISP process itself.
  4. Try to access another website that has the same IP address as the website you have.
