To simplify the Domain Name System (DNS) converts human readable domain names into machine-readable Internet Protocol (IP) address like www.a2zwebhelp.com to 18.104.22.168. Each device connected to the Internet has a unique IP address which other machines use to find the device.
How does DNS work?
An Internet Protocol (IP) address is given to each device on the Internet, and that IP address is necessary to find the appropriate Internet device – like a phone number to connect particular person or device. When a web user wants to load a webpage, a translation occurred between what a user types into their web browser (a2zwebhelp.com) and the machine-friendly address necessary to locate a2zwebhelp.com webpage.
Steps to loading a webpage:
1.As soon as you type a domain name, for example, a2zwebhelp.com into your web browser, your browser, and computer looks for the corresponding IP address in its local DNS cache or memory.
2.If a2zwebhelp.com isn’t in your computer’s cached memory, it expands the search out to the internet where it queries the DNS to determine if the domain exists in their DNS database. If the first DNS doesn’t find it on its server, it sends it to the next server until the right domain name server is found.
3.Once the DNS server finds the domain name a2zwebhelp.com, the server returns the domain name, and it’s IPS address to the requesting DNS server until it arrives back at your computer.
4.Once the IP address has reached your computer, your browser finds it on the internet. Next up, it communicate with the domain name hosted to request any associated files. The host server returns the files which display a2zwebhelp.com in your web browser.
