What is DNS and How Does It Work?

What is a nameserver? To understand the question, it's important to first understand what DNS (Domain Name System) is and how it works. DNS can be thought of as the internet's phone book. It allows us to use easily remembered domain names (e.g., google.com) instead of difficult-to-remember IP addresses. DNS translates these domain names into corresponding IP addresses, allowing our browser to connect to the correct server.

DNS servers form a globally distributed network. These servers store DNS records containing the mappings between domain names and IP addresses. When we want to visit a domain name, our computer first contacts the local DNS server (usually the server provided by our internet service provider). If the local DNS server doesn't have a record for that domain, the query is redirected to other DNS servers until the correct IP address is found.

DNS Component	Explanation	His duty
DNS Server	Servers that store mappings between domain names and IP addresses.	Translating domain names into IP addresses.
DNS Records	Data records containing information about domains (IP address, MX record, etc.).	Ensuring that the domain name is directed to the correct server.
DNS Query	A request to find the IP address of a domain name.	Initiate domain name resolution.
DNS Resolver	Software that runs on the user's device and manages DNS queries.	Sending queries to DNS servers and receiving responses.

This complex process occurs in the background within seconds when we access websites. Thanks to DNS, we can browse the internet without having to memorize the IP address of each website. This system is one of the fundamental elements that makes the internet user-friendly. In the next section, What is a nameserver? and we will examine in more detail what it is useful for.

To better understand the working principle of DNS, we can consider the following process:

1. The user enters a domain name into the browser. For example, example.com.
2. The browser sends a DNS query to the operating system. The operating system forwards this query to the configured DNS server (usually the ISP's DNS server).
3. If the DNS server has the IP address of this domain in its cache, responds directly. Otherwise, it contacts authoritative DNS servers.
4. Authoritative DNS servers provide DNS records that contain the correct IP address of the domain name. These records can be of different types, such as A record (address record).
5. The DNS server sends the obtained IP address back to the browser.
6. The browser connects to the web server via this IP address.
7. The web server sends the requested web page to the browser.

DNS works like the internet's address book, translating domain names into IP addresses and allowing users to easily access websites. What is a nameserver? To better understand the answer to the question, it is necessary to examine the role of nameservers in this process.

What are the Nameserver Types and Features?

Stages of the DNS Resolution Process

What is a nameserver? After understanding the answer to this question, it's also important to understand how a domain name is resolved and the steps involved. The DNS resolution process consists of a complex series of steps that begin when you type a domain name into a web browser and allow your browser to access the corresponding website. This process is one of the fundamental operating mechanisms of the internet, allowing users to use easily remembered domain names instead of complex IP addresses.

The DNS resolution process is often invisible to internet users. However, each step in this process is critical to the smooth and fast operation of the internet. The process begins with a user requesting access to a website and ends with the request being directed to the correct IP address. This process involves a series of queries and responses being exchanged between different DNS servers.

Stage	Explanation	Related Server
1. Starting a Query	The user types a domain name into the browser.	Local DNS Server
2. Recursive Query	The local DNS server references the root DNS servers.	Root DNS Server
3. TLD Server Query	Root servers point to TLD (Top Level Domain) servers.	TLD Server (.com, .net, etc.)
4. Authoritative Name Server Query	The TLD server points the domain name to the authoritative name server.	Authoritative Name Server

To better understand the DNS resolution process, we can review the following steps:

1. Starting a Query: The user types a domain name (for example, example.com) into the web browser.
2. Local DNS Server: The browser first sends this request to the local DNS server provided by the user's internet service provider (ISP).
3. Recursive Query: If the local DNS server does not store the domain name's IP address in its cache, it will contact the root DNS servers.
4. Root DNS Servers: Root servers direct the request to the relevant Top Level Domain (TLD) server (for example, .com or .net).
5. TLD Server: The TLD server is the authoritative name server for the domain name (nameserver) and transmits this information to the local DNS server.
6. Authoritative Name Server: The local DNS server obtains the IP address of the domain name by contacting the authoritative name server.
7. IP Address Forwarding: The authoritative name server sends the IP address of the domain name to the local DNS server.
8. Caching: The local DNS server caches this IP address for a specific period of time so that subsequent requests to the same domain name don't have to repeat these steps.
9. Connecting: The local DNS server transmits the IP address to the browser, and the browser connects to the web server via this IP address and displays the website.

This process is one of the fundamental principles of the internet's operation and allows users to easily access websites. Completing each step accurately and quickly directly impacts the quality of the internet experience. Therefore, nameserver Correct configuration and management of settings is of great importance.

What is the Relationship Between Domain and Nameserver?

Domain and What is a nameserver? The relationship between these two domains is critical to the functioning of the internet. A domain is the address of your website or email service on the internet. However, nameservers are the mechanism that determines which server actually hosts this address. Nameservers translate your domain name into an IP address, ensuring users are directed to the correct server. This translation is accomplished through a distributed system called DNS (Domain Name System).

When you register a domain, you need to specify which nameservers it will use. These nameservers are typically provided by your hosting provider. Nameservers direct requests for your domain name to the servers hosting your website or other internet services. If your nameserver settings are not configured correctly, users may not be able to access your website, or your email services may not work.

Domain Name	Nameserver	IP Address
example.com	ns1.hostingfirmasi.com	192.0.2.1
example.com	ns2.hostingfirmasi.com	192.0.2.2
example.net	ns1.baska Hostingfirmasi.net	203.0.113.1
example.net	ns2.baska Hostingfirmasi.net	203.0.113.2

The domain and nameserver relationship can be likened to the relationship between a home's address and a mailbox. A home's address (domain) allows someone to find a home, but a mailbox (nameserver) ensures that mail (internet traffic) arriving at that address reaches the right person. Therefore, ensuring that domain and nameserver settings are accurate and up-to-date is crucial for your continued online presence.

Relationship Characteristics

• The domain is connected to the nameserver.
• Nameserver shows the IP address of the domain.
• The DNS system manages this relationship.
• Incorrect nameserver settings can cause access issues.
• Up-to-date nameserver information ensures correct routing.

Understanding this relationship is crucial for ensuring the smooth operation of your website and other online services. Regularly checking your nameserver settings and updating them as needed can help prevent potential problems.

Domain DNS Records

Domain DNS records contain the IP address to which a domain name should be directed, the email server to use, and other important information. These records are stored on nameservers and ensure that internet users are directed to the correct resources. The most common types of DNS records include A records (for IP addresses), MX records (for email servers), CNAME records (for domain names), and TXT records (for text-based information).

Nameserver Change

A nameserver change is the process of updating the nameserver addresses used by a domain. This process is often necessary when changing hosting providers or making changes to domain settings. When a nameserver change is made, it can take some time for the change to propagate throughout the internet, typically between 24 and 48 hours. During this time, some users may be redirected to the old nameservers, while others may be redirected to the new ones.
