What is a DNS Lookup?
DNS (Domain Name System) is essentially the "phonebook" of the internet. When you type a domain name into your browser, your computer uses DNS to find the underlying IP address associated with that domain. Our DNS Lookup Tool allows you to query these records directly, providing a raw view of how your domain is configured across the globe.
The Power of Bulk DNS Checking
Manually checking DNS records for dozens of domains is time-consuming and prone to error. Our Bulk DNS Tool enables you to paste a list of domains or upload a file (TXT or CSV) to process hundreds of lookups in seconds. This is an essential feature for system administrators managing large portfolios and SEO professionals performing site audits.

Frequently Asked Questions
What is a DNS lookup?
A DNS lookup queries the Domain Name System for the records attached to a domain name, such as the IP addresses in its A and AAAA records or the mail servers in its MX records.
What is a bulk DNS lookup?
A bulk DNS lookup checks the records for many domains at once, which is useful when managing a large domain portfolio, migrating hosting or auditing email and SSL configuration.
How long does DNS propagation take?
DNS changes can take anywhere from a few minutes to 48 hours to propagate globally. This depends on the TTL (Time To Live) settings of your records.
Why is my DNS lookup failing?
A failure can occur if the domain is recently registered, the name servers are incorrectly configured, or the records have been deleted. Use our tool to verify each record type individually.
