What Is a DNS Lookup?
DNS Lookup shows you all the DNS records for any domain. It translates domain names into IP addresses and reveals how a domain is set up.
How Does It Work?
When you enter a domain, the tool asks DNS servers for all records linked to that domain. Each record type tells you something different about how the domain handles web traffic, email, and other services.
DNS Record Types
- A Record - Points a domain to an IPv4 address. This is what makes websites load.
- AAAA Record - Points a domain to an IPv6 address. This is the newer address format.
- MX Record - Lists the mail servers that receive email for the domain.
- NS Record - Shows the name servers that hold the official DNS records.
- TXT Record - Stores text data used for email security and domain verification.
- CNAME Record - Redirects one domain name to another.
- SOA Record - Contains admin info about the domain, like the primary name server and update timing.
When to Use DNS Lookup
- Find out why a website is not loading
- Check if your DNS changes have taken effect
- Verify email server settings
- See which hosting provider a domain uses
- Prepare for moving a domain to a new host
How to Use This Tool
Type a domain like example.com into the box and click Lookup. You will see all available DNS records grouped by type.
About DNS Propagation
After you change DNS records, it takes time for the changes to spread across the internet. This is called DNS propagation and can take up to 48 hours. You can use our DNS Propagation Check tool to see if your changes have reached servers worldwide.
Frequently Asked Questions
How long does DNS propagation take?
Most changes show up within a few hours. The full process can take up to 48 hours. It depends on the TTL value set on your records.
What is a TTL?
TTL stands for Time To Live. It tells DNS servers how long to remember a record before checking for a fresh copy. A lower TTL means faster updates but more server queries.
Can I see old DNS records?
No. This tool only shows current records. You need a passive DNS history service to see past records.
What if a record type returns nothing?
It means the domain does not have that record type set up. For example, no AAAA record means the domain does not support IPv6.
Is DNS Lookup safe?
Yes. DNS records are public information. Looking them up does not change anything on the target domain.
Why check TXT records?
TXT records hold important settings for email security like SPF and DKIM. They also verify domain ownership for services like Google Search Console.
