DNS Record Checker Tool
This free online tool allows you to instantly look up DNS records for any domain without using command-line
tools like nslookup or dig. Simply enter a domain name and get a detailed
breakdown of its DNS configuration, including TTL values, automatic provider
detection (Cloudflare, Google Workspace, etc.), and TXT record classification
(SPF, DKIM, DMARC, and more).

Reverse DNS lookup: IP address → domain name |
How DNS Works — A Quick Explanation
DNS (Domain Name System) acts as the internet's phone book. When you type a domain like
example.com into your browser, DNS translates it into an IP address (e.g.,
93.184.216.34) so your browser can reach the correct server. This process is called
name resolution and typically takes just milliseconds.
What is TTL?
TTL (Time To Live) is the duration in seconds that a DNS record is cached. A TTL of 300 means
the record is cached for 5 minutes. Lower TTL values enable faster propagation of DNS changes, while higher
values reduce load on DNS servers.
What is DNS Propagation?
After you update a DNS record, it can take time for the change to spread (propagate) across all DNS servers
worldwide. This process can take anywhere from a few minutes to 72 hours, depending on the
TTL of the old record and your ISP's DNS caching behavior.
