What is DNS?
DNS (Domain Name System) is the internet’s phonebook. It translates human-readable domain names into machine-readable IP addresses, ensuring that users connect quickly and reliably to the websites and services they need.
How does DNS propagate?
DNS propagation is the process of spreading updated domain records across the internet. When you make a change, it starts at your domain’s primary DNS server, then gradually updates on servers worldwide until your new settings are fully live and accessible everywhere.
How do I do a DNS lookup?
Simply enter your domain name, choose the record type from the dropdown menu, and click “Look up.” You’ll instantly see whether your DNS records are resolving correctly.
What DNS record should I look up?
A
The IPv4 address (A) record maps your domain to a specific server by pointing it to an IP address. It tells browsers where your website is hosted, using the legacy IPv4 addressing system.
AAAA
The IPv6 address (AAAA) record links your domain to a modern, next-generation IP address. It directs browsers to the server hosting your website, using the IPv6 system built for scalability and future growth.
CNAME
The Canonical Name (CNAME) record creates an alias by pointing one domain to another. For example, if someone types example.com, the CNAME can redirect them seamlessly to www.example.com.
NS
The Nameserver (NS) record specifies which DNS servers are authoritative for your domain. It tells the internet where to look for the correct records so your website can be found and loaded properly.
MX
The Mail Exchange (MX) record routes emails for your domain to the correct mail server. It ensures that messages sent to addresses like user@yourdomain.com are delivered to the right inbox.
TXT
The Text (TXT) record lets you add notes or data to your domain in a readable format. It’s most often used for verifying domain ownership, improving email security, and adding details like company information.
SOA
The Start of Authority (SOA) record defines key details about a domain, including ownership, the primary nameserver, and the last time records were updated. It also sets the rules for how DNS zones are synchronized across servers.
PTR
The Pointer (PTR) record links an IP address back to a domain name. Also called a reverse DNS lookup, it confirms which domain is associated with a specific IP—commonly used for email validation and security.
SPF
The Sender Policy Framework (SPF) record specifies which mail servers are authorized to send email for your domain. It helps prevent spoofing and ensures your messages aren’t flagged as spam or phishing.
Why is DNS lookup important?
When you switch hosting providers or launch a new website, the first few days are crucial for DNS propagation. Until updates spread worldwide, your site may not load correctly. Global DNS is the backbone that keeps websites connected and accessible everywhere.
Our free DNS checker lets you instantly see how far your domain has propagated and detect any issues with your DNS records.
Why does checking DNS propagation matter?
Checking DNS propagation matters because it shows whether your domain changes are live across the internet. Without full propagation, some users may not reach your website, emails can fail to deliver, or old records may still resolve.
What is the difference between DNS and IP address?
DNS is like the internet’s phonebook, translating easy-to-remember domain names into IP addresses. An IP address is the unique numerical identifier that points directly to the server hosting your website or service.
Why is DNS required?
DNS is required because it makes the internet usable. Instead of memorizing long IP addresses, users can type domain names, and DNS translates them into the correct server so websites, apps, and emails work seamlessly.
How long does DNS propagation take?
DNS propagation typically takes a few hours but can last up to 48 hours worldwide. The time depends on factors such as TTL (time-to-live) settings and how quickly ISPs refresh their cached records.
What happens if DNS is not working?
If DNS isn’t working, your website may not load, emails may fail to deliver, and online services tied to your domain could be unreachable until the issue is fixed.
Can I speed up DNS propagation?
You cannot force global propagation, but you can reduce TTL values before making changes. This makes ISPs update records faster. Using reliable DNS servers also helps ensure quicker updates.
