DNS checker
My DNS Checker is a tool that allows you to analyze your domain’s DNS (Domain Name System) configuration.
DNS is crucial to the operation of the Internet because it is responsible for converting domain names (such as example.com) into IP addresses that computers can understand.
With this tool, you can detect and fix problems in your DNS settings.
What is DNS?
DNS acts as the “phone book” of the Internet. When someone enters a domain name into their browser, DNS translates that name to the corresponding IP address of the server where the Web site is hosted. Good DNS settings ensure that your Web site is accessible and performing well.
Why use a DNS Checker?
- Troubleshooting: Track configuration errors, such as incorrect DNS records, that can lead to connection problems.
- Security: Check that your DNS settings are secure, such as by verifying that DNSSEC is enabled to protect against DNS spoofing.
- Performance: Verify that your DNS settings are configured correctly to improve your website load times.
- Full configuration: Check all DNS records, such as A records, MX records, CNAME records, TXT records and more.
How does the DNS checker work?
- Enter your domain: Type or paste the domain name you want to check into the DNS Checker.
- Automatic check: The tool performs a DNS lookup to retrieve all relevant DNS records for your domain.
- Receive Results: Get a detailed report with all DNS records, including A, AAAA, MX, CNAME, TXT, NS, and more.
- Take Action: Use the results to fix problems with your DNS configuration and improve the security and performance of your Web site.
Examples of DNS records being checked:
- A-record: Refers a domain to an IPv4 address.
- AAAA record: Refers a domain to an IPv6 address.
- MX record: Specifies the mail server for the domain.
- CNAME record: Refers a domain to another domain.
- TXT record: Contains textual information, often used for verification, such as SPF, DKIM, and DMARC.
- NS record: Indicates the name servers that have authority over the domain.
With my DNS checker, you can easily analyze and optimize your domain’s entire DNS configuration. By regularly checking your DNS settings, you can prevent potential connection problems, improve security and optimize your website’s performance.
