DNS Test
Resolve all DNS records for a domain and audit mail security — SPF, DMARC, and DKIM.
In short
DNS Test checks a domain's DNS configuration for potential problems and missing settings. Use it to identify DNS issues affecting website resolution, email delivery, domain services, and other configurations that depend on correctly configured DNS records.
What Is a DNS Test?
A DNS Test is a diagnostic check of a domain's DNS configuration. While a DNS lookup shows which records are currently returned, a DNS test focuses on whether the configuration appears complete and whether important DNS settings may need attention.
SEOsoft's DNS Test is designed to highlight potential DNS problems and missing configuration so you can investigate issues before they affect website or domain services.
What Does a DNS Test Check?
A DNS test looks beyond simply displaying DNS records. It evaluates the available DNS configuration for conditions that may indicate a problem, an incomplete setup, or a missing record.
This makes DNS Test useful when you already suspect something is wrong and need a diagnostic view rather than simply a list of DNS records.
Find Missing DNS Records
Some DNS-dependent services require specific records to be present. A missing or incomplete record can cause problems with website connections, email delivery, domain verification, or third-party services.
DNS Test helps identify potential missing configuration so you know where to investigate.
Identify DNS Configuration Problems
DNS problems can be difficult to spot by looking at individual records. A record may exist while another related setting is missing or incorrectly configured.
DNS Test highlights potential configuration problems so you can focus your troubleshooting on the DNS settings that may require attention.
DNS Test for Website Troubleshooting
If a domain is not resolving correctly, a website is intermittently unavailable, or a newly configured service is not working, DNS configuration is worth checking.
DNS Test provides a diagnostic view that can help identify DNS-related issues and missing settings before you make changes to your domain configuration.
DNS Test for Email and Domain Services
DNS supports more than website resolution. Email systems, domain verification, authentication, and other online services can depend on correctly configured DNS records.
A DNS test can help identify configuration gaps that may affect these services and give you a clearer starting point for troubleshooting.
DNS Test vs DNS Lookup
DNS Lookup and DNS Test serve different purposes.
DNS Lookup is primarily used to see which DNS records a domain currently returns. It is useful when you want to inspect the current state of a domain's DNS.
DNS Test is designed for diagnosis. It looks for potential problems and missing configuration so you can focus on settings that may need attention.
Use DNS Lookup when you want to inspect the records. Use DNS Test when you want to investigate whether something is wrong.
When Should You Run a DNS Test?
Run a DNS test when setting up a new domain, changing DNS providers, moving hosting, configuring email, connecting third-party services, or troubleshooting a domain that is not working as expected.
It can also be useful after making DNS changes to check whether the configuration appears complete.

How DNS Test Works
Enter the domain you want to test and run the check. SEOsoft examines the available DNS configuration and evaluates it for potential problems or missing settings.
The results highlight areas that may require attention so you can investigate the relevant DNS records and configuration.
Limitations of this tool
- DNS configuration can vary depending on DNS propagation, resolver location, caching, and the timing of recent changes. A test result therefore represents the configuration that can be observed at the time of the check.
- A warning or missing-record result does not necessarily mean that a domain is completely broken. Some DNS records are optional or depend on the services a domain uses, so results should be interpreted in the context of the domain's intended configuration.
Frequently asked questions
- What is a DNS Test?
- DNS Test is a diagnostic tool that checks a domain's DNS configuration for potential problems and missing settings. It is designed to help identify issues that may not be obvious from simply viewing individual DNS records.
- What is the difference between DNS Lookup and DNS Test?
- DNS Lookup shows the DNS records currently returned for a domain. DNS Test focuses on diagnosing the configuration by identifying potential problems, missing settings, or conditions that may require attention.
- How do I test my DNS configuration?
- Enter your domain into SEOsoft DNS Test and run the check. The tool evaluates the available DNS configuration and highlights potential issues or missing settings.
- Why should I test my DNS settings?
- Testing DNS can help identify configuration problems that may affect website resolution, email delivery, domain verification, or other services that rely on DNS.
- Can DNS Test find missing DNS records?
- Yes. DNS Test is designed to highlight potential missing DNS configuration where the expected setting can be determined from the available information.
- Can DNS problems affect my website?
- Yes. Incorrect or incomplete DNS configuration can prevent a domain from resolving correctly or cause other services connected to the domain to stop working as expected.
- Can DNS problems affect email?
- Yes. Email delivery depends on DNS configuration, particularly MX records and, depending on the setup, additional authentication-related records. Problems with these settings can affect how email is delivered or authenticated.
- Will DNS Test tell me exactly how to fix every problem?
- DNS Test identifies potential DNS configuration problems and missing settings, but the correct fix depends on your hosting provider, DNS provider, email service, and intended domain configuration.
- How long does it take for DNS changes to take effect?
- DNS changes can take time to propagate and may appear differently across DNS resolvers while cached records expire. A recent change may therefore not be visible everywhere immediately.
- Should I use DNS Lookup or DNS Test?
- Use DNS Lookup when you want to inspect the records currently returned for a domain. Use DNS Test when you want a diagnostic check that focuses on potential problems and missing configuration.
