DNS records are the foundation of how the internet works. Without DNS, we wouldn't be able to do simple internet functions like sending emails and performing Google searches. There are great tools like MoarDNS that make it easy to find these records, explain how they work, and even generate useful CSV data out of them.
Your computer uses the Domain Name System to convert human-readable domain names into numerical IP addresses. When you enter a domain name into your web browser, your computer contacts a DNS server to look up the IP address for that domain.
Every time you type in a domain, your computer contacts a DNS server for it's IP address. It does this until it finds the correct one.
Domain names are used to register a website on the internet, and there are different kinds of DNS records which map domain names to addresses. For example, A records map domain, with IPv4 addresses while AAAA records map domains, with IPv6 addresses.
The Domain Name System (DNS) is useful when troubleshooting website problems. You can use a DNS lookup tool if you can't access a website to find out whether the issue is with the DNS or the website.
DNS stands for Domain Name Server and can be described as the address for different types of resources. There are many types of DNS records, and each has a specific function such as how Google's A record gives you their IP address.
When you type a URL into your web browser, your computer then contacts the DNS server and asks for the IP address of the website you want to visit. The DNS server will respond with the IP address and connect you.
DNS lookup tools, can be used as a troubleshooting method and to check DNS, before adding records. This is often helpful when creating a new website or setting up an email account.
DNS records tell you the information about a domain such as an address, mail server and name servers. There are four types of DNS records: A, CNAME, MX, and NS.
A Record holds the IP Address of a Domain.
CNAME records are used to store alias information for a domain. For example, if you want www.example.com and example.com to point to the same website, you would create a CNAME record for www that points to example.com.
The MX record stores information about which server is responsible for email.
NS Records store information about which name servers are responsible for a domain.
Here are some tools for performing DNS lookup
DNS tools are a great way to learn about DNS records and how they work. You can access the website's IP address, MX records, and TTL results with just one click. By running a DNS lookup on your domain, you can look up any records associated with the domain name. This is helpful for troubleshooting or understanding how the DNS system works.
Using a DNS lookup tool, you can get all DNS records for one domain. This includes information about the type of the record, how long it will continue to work (its TTL) and what it does.
You can use DNS lookup tools to see if there are any problems with the A records associated with your website. If the record has an incorrect value or is unrelated, the problem could stem from that.
DNS lookup tools allow you to take a closer look at how domain name servers operate and resolve technical issues with specific websites.
