What does DNS Lookup mean?
A DNS Lookup is a query to get the published DNS details for a particular domain name. The Domain Name System (DNS) is a service that resolves human-readable domain names like example.com to machine-readable IP addresses computers use to communicate.
What kind of DNS records can this tool query?
It performs a DNS look up and fetches the most popular DNS record types found on the Internet:
- A — IPv4 address that the domain resolves to.
- AAAA — AAAA record is an IPv6 address associated with the domain.AAAA — AAAA record: IPv6 address associated with the domain.
- MX — Mail exchange servers that receive email.
- TXT — Text records are typically used for SPF, DKIM, DMARC and domain verification.
- NS — Authoritative name servers for the domain.
- CNAME — Canonical name (alias) that points one hostname to another.
- SOA — Start of Authority record which carries the administrative information of the DNS zone.
- PTR — Reverse DNS record, which is used to be able to resolve an IP address back to a hostname.
How to Use the DNS Lookup Tool
The typical DNS lookup takes a couple of seconds to return the DNS records and IP addresses.
- Type in a complete DNS name (e.g., example.com).
- Don't use http:// or https://.
- Press the Lookup DNS button.
- Easily analyze the results by record type.
Tips for Accurate DNS Lookups
- The results for an example.com search may differ from www.example.com or any other variation.
- Give it 48 hours for DNS to propagate after changing the DNS records.
- Check the TTL (Time To Live) value. The longer the TTL, the longer this information is kept in cache; the shorter the TTL, the quicker the changes will reach the user.
- Ensure A, AAAA, and NS records are properly set up when a website does not load correctly.
What's the Purpose of DNS Records?
DNS is a key component of the internet communication system. There are various types of DNS records that have different functions:
- A and AAAA records are used to link to a website.
- MX records are responsible for how email is sent.
- TXT records aid email verification and domain authentication.
- CNAME records make it easier to manage subdomains.
Any kind of DNS configuration glitch can make a site inaccessible, block out e-mail or create verification problems. A DNS lookup tool can help you to identify and solve these issues within a short period of time.

Frequently Asked Questions
What is DNS?
The Domain Name System (DNS) is the worldwide directory service that translates domain names into IP addresses. A DNS look up is an operation carried out with this directory.
Is the DNS Lookup Tool Free?
Yes. The DNS lookup tool is 100% free to use. No registration, daily limits, captchas are required.
The answer is: A record holds a lot of information.The answer is: A record contains a lot of information.
The A record stores the IPv4 address of a domain. It's one of the most critical types of DNS records, as it allows browsers to access the proper web server.
What is the Difference Between A Record and AAAA Record?
The AAAA record type contains an IPv6 address, for example 2001:db8::1, and the A record type contains an IPv4 address, for example 192.0.2.1. Several of them are used for modern domains.
What could be the reason for a DNS lookup to return no result?
If no records are returned, it is possible that the domain is not registered, the requested record type does not exist or the domain name may be misspelled. Check another domain to ensure that the tool is working.
Are you able to look up DNS records for a subdomain?
Yes. You can do a DNS lookup on any domain name - even subdomains like blog.example.com or mail.example.com.
