A domain is the most crucial part of your website or the blog once you have done creating your website. After you are done setting up your business, and you try to go online with your business, you need a website and to get a website, you need a web hosting service provider. You can own a site from the web hosting service provider, he not only gives you a website along with it, he provides an email and also some security services to your site. The website provided to you by the website hosting service provider contains an address often called as a domain address.
Many domain names are connected to make a domain name system. The domain name system includes many domain names used by different users to maintain their website. These Domain Name systems are helpful to match the IP address to the website, which is often used by people to locate a site. The domain name systems are like a database that store data of all websites. These databases contain files that inform a web server how to respond to a request which is otherwise called as DNS records.
Whenever a web server sends a request to view a particular website, the request is first sent to the DNS database, and the DNS database looks for the files related to that website. It then finds the IP address of that website and forwards it to the webserver. Mapping Files is the other name for DNS records.
We also use letters often called as DNS syntax, and the most common letters used in this DNS Syntax are A, AAA, CNAME, MX, PTR, NS, SOA etc.
The DNS Syntax is: -
A- IP address of the website.
AAAA- IPv6 address which maps hostname with a 128-bit IPv6 address.
CNAME- the canonical name is used to map names with DNS records.
MX- Mail exchange servers use this.
PTR - It maps the IPv6 address to the canonical name and also shows pointer records.
NS - It means name server, and it is helpful to check the server on which the domain is residing.
SOA- Start of Authority. It contains all the information about the domain which the user is using.
SRV- It shows the TCP connection used by the user.
TXT- It is used to enter text in the DNS records.
HINFO- It gives the information about the host on which the domain is operating. It provides information about the OS and the version of the CPU used by the host.
ISDN - Integrated Services Digital Network services is a kind of telephone service that contains the country code, destination code, subscriber id and the sub address of the ISDN customer.
As mentioned above the DNS records contain all the vital information about the website and share with the web server when required. If you want to check the IP address of your website or get any address of subdomains present in that domain and the updating details of the domain along with the refresh rate.
Finding a DNS record is a piece of cake if you have an internet connection. DNS record checker is available online for free, and you can get it by searching on your search engine.
Search for online DNS checker from your search engine and click on any online tool and then enter the domain name of the website for which you want to find the DNS records and click on SUBMIT. Now you have all the files of the site that contains all the information about the website such as A, AAAA, SOA etc.
You can also do a Google DNS check, Whois Lookup or dig DNS to find the IP address using a lookup.
After knowing the DNS records of the domain, I think now you can understand that no website can operate without the DNS file. As a website owner and an SEO manager, you need to understand the working of a website, and to do so, and you need to have complete information about the DNS records of the website. After having this information, if you face any problems on your website from the web hosting site, then you can tell your web hosting service provider to solve the particular issue as you know about the subject.
