DNS Lookup

DNS Lookup Tool

Use the DNS Lookup tool to check the DNS records associated with a domain name. It helps you view important information about how a domain is configured, including IP addresses, mail servers, nameservers, verification records, and DNS zone information.

How to Check DNS Records

1. Enter the domain name you want to check, such as example.com.
2. Click Submit to perform the DNS lookup.
3. Review the available DNS records returned for the domain.

What DNS Records Can You Check?

Depending on the DNS configuration of the domain, the tool may return the following record types:

• A records – show the IPv4 address associated with a domain.
• AAAA records – show the IPv6 address associated with a domain.
• MX records – identify the mail servers configured to receive email for the domain.
• NS records – show the nameservers associated with the domain.
• TXT records – display text-based DNS information that may be used for domain verification, email authentication, and other configuration purposes.
• SOA records – provide information about the DNS zone, including administrative and timing values.
• CAA records – show which certificate authorities are authorized by the domain's CAA configuration.

Understanding DNS Lookup Results

The information displayed depends on the type of DNS record found. Results may include fields such as the host, TTL, IP address, target, priority, nameserver, entries, flags, tags, and values. SOA records may also include information such as the primary nameserver, responsible name, serial number, refresh interval, retry interval, expiration time, and minimum TTL.

What Is DNS Lookup Used For?

A DNS lookup can help website owners, developers, and system administrators inspect a domain's DNS configuration. It can be useful when checking where a domain points, reviewing nameservers, verifying mail server settings, inspecting DNS changes, or troubleshooting domain-related configuration issues.

Why Check DNS Records?

DNS records control important aspects of how a domain and its related services operate. Reviewing these records can help you understand the current DNS configuration, verify that expected records are present, and identify settings that may need further investigation.
