About DNS Lookup Tool

DNS (also known as a forward DNS lookup) is basically like a directory that translates web server domain names into IP addresses. So, instead of manually typing in the IP address numbers for every website you want to search for, the DNS automatically converts the website name for you. DNS allows computers and web servers to communicate with one another easily.

DNS lookup is the process of querying a record from a domain name system server. The forward DNS Lookup can be used to find IP addresses for a specific domain name, and to find out more information. This is the opposite of a reverse DNS lookup that translates IP addresses to domain names. There are various programs and online tools for performing lookups.

This can be compared it a phonebook in which people can search for domain names like www.example.com and find the IP addresses behind them without the need to remember long strings of numbers like 192.0.32.10 (IPv4) or 2620:0:2d0:200::10 (IPv6). This is created to make communication with web servers easier both for humans and machines.


DNS Lookup Usage Example

For example, when you search for the domain name https://www.example.com, it returns the DND address or IP address 192.0.32.10 (IPv4) and 2620:0:2d0:200::10 (IPv6).

In order to clarify the process of this DNS lookup, we need a brief application example we just mentioned. Let's Suppose we want to search for the domain via a browser to “https://www.example.com” web server. For this, the system needs the server’s IP address. The system first checks locally if the domain name entered is in its cache or in its hosts’ file. If this is not in its cache or host fils, it asks the responsible server. This system of query was assigned to it via DHCP or is configured permanently.

If the server can supply the request itself, it gives the result to the requester. If not, it contacts another server responsible for the domain. With the supplied IP address, the browser can communicate with the domain webserver via the IP network.

Another usage of the use of DNS lookup is the checking and filtering of emails by an email server and also checking the speed of a web server is also possible. Checking the IP Addresses with DNS Lookup for backlink and off-page profile of a web site is also important. Companies continue to search about DNS and IP Addresses for better SEO processes.
