DNS Lookup tool fetches all DNS Records of a domain and shows as received. If you changed your hosting or DNS records, then this tool is for you to verify that your records are entered correctly to avoid any downtime. The records fetched by this tool are A, AAAA, CNAME, MX, NS, PTR, SRV, SOA, TXT, CAA. Select any record which you want to check or select ANY to get all DNS records of your domain.
In computer jargon, DNS records are called ‘mapping files.’ When a web server sends a request by a user to visit a particular website, the request is sent to the DNS database. This database looks up its records, finds the website’s IP address and forwards it to the requesting server. After getting this information, the requesting server uses the IP address to find the website and display it to the user who initiated the request.
There are letters associated with the DNS records which are known as DNS syntax. Some of the commonly used syntax with all DNS records are; A, AAAA, CNAME, MX, PTR, NS, SOA, SRV, TXT and NAPTR.
The ‘A’ syntax in a DNS record is the most basic type of syntax. It stands for ‘address’ and indicates the IP address of the website.
The ‘AAAA’ record is an IPV6 address which maps the hostname to a 128-bit IPV6 address.
The ‘CNAME’ stands for ‘conical name’ and is used to associate sub-domains with existing DNS records.
The ‘MX’ stands for mail exchange and is used for mail exchange servers.
The ‘PTR’ record as the name indicates a pointer record and maps an IPV4 address to the CNAME.
The “NS’ record stands for ‘name server’ and indicates the server on which the domain resides.
The ‘SOA’ record stores important information about the domain, like when was it last updated, etc.
The “SRV’ record indicates which TCP service the domain operates.
The ‘TXT’ record permits the website’s administrator to insert any text in the record.
Why do you need to look at DNS records?
The DNS records of any website contain vital information for webmasters and SEO. These records give you details regarding any website that you might be interested in viewing. If you want to know the IP address of a domain, you can get this information by looking at the DNS records of that domain. An IP address will tell you from which address domain is being hosted, and if you know the structure of IP addresses you will also know in which country the domain is being hosted. IP addresses are assigned like telephone numbers. We know that each country has been assigned a particular number followed by city code and then the actual telephone number. To make an international call, you have to dial the international code, area code and the actual number to
make the call. Similarly, IP addresses are also assigned following a particular structure.
The other important information that you get when you view DNS records is the addresses of any sub-domains that are associated with the domain. Also when the domain was last updated, what is its refresh rate, etc.?
You might want to check a competitor’s DNS records and see where it is being hosted from and other information about the website. DNS records are helpful for webmasters and SEOs when setting up or managing a website.
Getting and studying DNS records is important for SEO and webmasters. Once you decide to use a web hosting service, you will want to know your website’s IP address and the additional services provided by the web servers for your domain. If the internet service is slow or the refresh rate is slow, you can ask your web hosting service provider to improve them.
No website can operate without its DNS records being stored in the DNS database. It’s the database that holds all the necessary information about a website.
It’s the server that all web servers use to process visitors requests, and it guides them to the correct location. For example, a website owner might decide to change the web hosting service provider and move the domain to a better provider. When he or she signs up on the new hosting servers, the first action that will take place is that the domain’s information contained in the DNS records will be updated.
Without DNS records no website can operate on the internet.
