Understanding the Basics of DNS
If you want to manage your website’s DNS effectively, you need to have a basic understanding of how DNS works. DNS stands for Domain Name System, and it’s a system that translates domain names into IP addresses, allowing users to access websites using human-readable domain names instead of IP addresses.
The DNS hierarchy is a structure that ensures that DNS requests are routed to the appropriate servers. At the top of the hierarchy are the root servers, which contain information about top-level domains such as .com, .org, and .net.
When you type a URL into your browser, your computer sends a request to your ISP’s DNS server. If the DNS server has the information in its cache, it will return the IP address to your computer. Otherwise, the request will be sent up the hierarchy until it reaches a server that can provide the IP address.
Each domain name has a corresponding DNS record, which contains information about the domain’s IP address and other settings such as the time-to-live (TTL) value. The TTL value determines how long a DNS server can cache the record before it expires and needs to be refreshed.
There are several types of DNS records, including A records, which map domain names to IP addresses, and CNAME records, which map domain names to other domain names. Understanding these record types is crucial to effectively managing your website’s DNS settings.
What is DNS and How Does it Work?
DNS, or Domain Name System, is a system that converts domain names into IP addresses. Every website has a unique IP address that identifies it on the internet. However, remembering the IP address of every website is impossible. DNS acts like a phonebook for the internet, translating domain names into IP addresses so that we can easily access websites.
When you enter a website’s domain name into your browser, your computer sends a request to a DNS server to resolve the domain name into its corresponding IP address. The DNS server then sends the IP address back to your computer, allowing your browser to establish a connection with the website’s server and load the website.
- DNS resolution: The process of converting a domain name into an IP address is known as DNS resolution. It involves multiple steps, including querying DNS servers and caching IP addresses to improve performance.
- DNS hierarchy: The DNS system is organized in a hierarchical structure, with top-level domains (TLDs) like .com and .org at the top and individual domain names at the bottom.
- DNS records: DNS records are used to store information about a domain name, including its corresponding IP address, mail servers, and other DNS servers responsible for the domain.
- DNS propagation: Changes made to DNS records can take some time to propagate across the internet, meaning that it may take some time for everyone to see the changes.
Understanding how DNS works is crucial for managing websites and ensuring their accessibility on the internet. In the next section, we will discuss how to retrieve your server DNS and why it is important to do so.
The Different Types of DNS Servers Explained
When it comes to DNS servers, there are several types that you should be aware of. Each of these servers has a specific function and purpose in the overall functioning of the DNS system. Here are some of the most common types of DNS servers:
- Recursive DNS Servers: These servers are responsible for making requests to other DNS servers on behalf of the user or client. They work by querying multiple DNS servers until they find the IP address associated with the requested domain name.
- Root DNS Servers: These are the top-level DNS servers that contain the authoritative information about all top-level domains. They are responsible for directing requests to the appropriate top-level domain server.
- TLD DNS Servers: These servers are responsible for storing information about specific top-level domains, such as .com, .org, and .net. They provide information about the authoritative name servers for each domain.
- Authoritative DNS Servers: These servers store the actual DNS records for a specific domain name. When a recursive DNS server requests information about a domain name, the authoritative DNS server is the one that provides the answer.
Understanding the different types of DNS servers and their functions is important for managing your website’s DNS settings effectively. By knowing which servers are responsible for which tasks, you can more easily diagnose and resolve DNS-related issues.
