Look up DNS records (A, AAAA, CNAME, NS, MX, TXT, SOA, PTR, SPF) via DNS-over-HTTPS across multiple resolvers.
Resolver | Name | Type | TTL | Value |

Note: Results reflect each resolver’s cache and view; propagation may vary.
The Domain Name System (DNS) works like the internet’s phonebook. It converts easy-to-remember domain names into machine-readable IP addresses, making sure users reach the right websites and services quickly and reliably.
DNS propagation is the process of distributing updated domain records across the internet. When you update your DNS, the change begins at your domain’s primary nameserver and then spreads to DNS servers worldwide until the new settings are active and accessible everywhere.
Just type in your domain, select the record type from the menu, and hit “Look up.” In seconds, you’ll know if your DNS records are resolving properly.
An IPv4 A record links your domain to a server by pointing it to an IPv4 address. It tells browsers where to find your website, using the traditional IPv4 system.
An IPv6 AAAA record connects your domain to a next-generation IPv6 address. It guides browsers to the server hosting your website, using the scalable IPv6 system designed for the future of the internet.
A Canonical Name (CNAME) record creates an alias that points one domain to another. For example, typing example.com
can automatically direct users to www.example.com
without issues.
A Nameserver (NS) record defines which DNS servers are authoritative for your domain. It directs the internet to the correct records so your website can be located and loaded correctly.
A Mail Exchange (MX) record directs email for your domain to the appropriate mail server. This ensures that messages sent to addresses like user@yourdomain.com
are delivered to the correct inbox.
A Text (TXT) record allows you to store readable information within your domain’s DNS. It’s commonly used for verifying domain ownership, enhancing email security (SPF, DKIM, DMARC), and adding extra details such as business or service data.
A Start of Authority (SOA) record contains essential information about a domain, such as the administrator, the primary nameserver, and the most recent update. It also defines how DNS zone data is managed and synchronized across servers.
A Pointer (PTR) record maps an IP address to a domain name. Known as reverse DNS lookup, it verifies which domain is tied to an IP—most often used for email authentication and security checks.
A Sender Policy Framework (SPF) record defines which mail servers are allowed to send email on behalf of your domain. This protects against spoofing and helps keep your messages from being marked as spam or phishing attempts.
DNS lookups are essential whenever you switch hosting providers or launch a new website. During the first days, DNS propagation determines how quickly updates spread across the globe.
Until the changes reach all servers, your site may load inconsistently. DNS is the backbone that ensures websites stay connected and accessible worldwide.
Our free DNS checker shows you how your domain records are propagating worldwide and helps identify any issues with your DNS configuration.
DNS propagation checks confirm if your domain updates are active worldwide. Until records fully propagate, some visitors may not reach your site, emails might bounce, or outdated DNS data could still be used.
DNS works like the internet’s phonebook, converting human-friendly domain names into IP addresses. An IP address is the unique numeric identifier that connects directly to the server where your website or service is hosted.
DNS is essential for usability on the internet. Without it, you’d have to remember long IP addresses. DNS lets users type simple domain names, then translates them into the right server so websites, apps, and emails function smoothly.
DNS propagation usually completes within a few hours, but in some cases it can take up to 48 hours globally. The speed depends on factors like your DNS record’s TTL (time-to-live) settings and how often different ISPs update their cached data.
If DNS fails, your domain services stop working. This can cause websites to go offline, emails to bounce, and apps or online tools linked to your domain to become inaccessible until the issue is resolved.
Global DNS propagation can’t be forced, but you can speed it up by lowering TTL values before making changes. This prompts ISPs to refresh records more quickly. Choosing reliable DNS servers also improves the chances of faster updates.
