DNS Hosting

The hierarchical and distributed naming system known as the Domain Name System (DNS) is used to identify devices that can be accessed over the Internet or other Internet Protocol (IP) networks. Through resource records in the DNS various types of information about the domains are linked together. Internet domain names are identified and converted into Internet Protocol (IP) addresses using the domain name system (DNS). For instance, a server in the background transfers a user's typing of "example.com" into a web browser to the associated IP address. 203.0.113.72 is comparable to an IP address in structure.

DNS has been enhanced throughout time to carry out a variety of different tasks in addition to their most frequent usage of mapping human-friendly domain names to the numerical IP addresses computers require to find different services and devices. Since 1985, the Domain Name System has played a crucial role in the operation of the Internet.

The majority of internet activities, including web browsing, rely on DNS to rapidly deliver the details required to link users to distant DNS hosts. On the internet, DNS mapping is dispersed according to a hierarchy of authority. Governments, universities, and other institutions, as well as access providers and businesses, frequently have their own allotted IP address ranges and domain names. In most cases, they also control the DNS servers that translate those names to those addresses. The domain name of the web server that processes client requests serves as the foundation for the majority of Uniform Resource Locators (URLs).

DNS History

In the 1970s, Elizabeth Feinler from the Stanford Research Institute kept a single file named "HOSTS.TXT" that included all hostnames and their accompanying numerical addresses. Feinler manually assigned numerical numbers to domain names in this directory, which became known as the Advanced Research Projects Agency Network, or ARPANET. Calling Feinler was necessary to enter a new name in the directory.

This method was too ineffective to continue by the 1980s. The domain name system was developed in 1983 to disperse what had previously been a single, centralized file containing each address among several servers and locations.

According to the IETF, one of the earliest internet standards was the DNS system in 1986. That group released two publications, RFC 1034 and RFC 1035, outlining the DNS protocol's specifications and the kinds of data it could convey. To suit the increasingly complicated internet since then, DNS has been regularly upgraded and expanded. Large, all-encompassing information technology firms like Google and Microsoft now provide their DNS Hosting services as well.

How Does a DNS server Work?

The following phases make up the fundamental process of a DNS process:
First of all, a Website Address or Domain name is searched by the user in the browser.
To determine the domain’s IP or network address, the browser sends a message to the network known as a recursive DNS query.
Then a request is received by the recursive resolver, also referred to as a recursive DNS server, which is usually operated by the Internet Service Provider. The recursive resolver sends the address back to the user if it has it, and the website is loaded on the user’s browser.
The authoritative name servers, top-level domain (TLD) name servers, and DNS root name servers will all be consulted if the recursive DNS server is unable to resolve the issue.
All three server types continuously reroute the traffic together until they locate a DNS address that has the requested IP address. The user's desired website loads once this information is sent to the recursive DNS server. DNS root name servers and TLD servers mostly redirect requests rather than solve problems directly.
The A record for the domain name, which includes the IP address, is kept in the recursive server's cache. The following time it gets a request for that domain name, it answers the user directly rather than asking other servers for information.
It returns an error if the query reaches the authoritative server, and it cannot find the information.

DNS Architecture

A URL typically contains the domain name. A domain name is composed of several labels. Each part of the domain hierarchy represents a subdivision and should be read from right to left. Following the period in the domain name is the TLD. There are several top-level domains, but some examples include .com, .org, and .edu. Some domains, like .us for the United States or .au for Australia, indicate a country code or specific geographic area.

Each label next to the TLD on the left indicates a different subdomain of the domain on the right. For instance, "Hostdive" is a subdomain of .com, and "www." is a subdomain of hostdive.com in the URL www.hostdive.com.

Each label can have up to 63 characters, and there can be 127 levels of subdomains. Up to 253 characters can be used in the domain's total character count. A numeric TLD name is prohibited, and labels cannot begin or finish with hyphens.

DNS Caching

When you visit a website once on your browser, the information is kept on your device so that your computer doesn't have to call a DNS server to resolve the domain name with the IP address. Instead of asking the DNS nameserver for the IP address each time you input the domain name. This method is called DNS caching.

Additional caching can take place on the servers of the user's ISP as well as on the routers that link clients to the internet. With so much caching taking place, there are much fewer queries that reach the DNS name servers, which improves the system's speed and effectiveness!
