Domain Info & Health Check

Domain Explorer provides general and security information about a domain. Just enter the domain name and press the Free Scan button. It provides the following information:

1. Domain WHOIS

WHOIS information includes details about the domain registration such as the registrar, registration date, expiration date, and contact information for the domain owner. This data helps identify who owns the domain and the associated administrative and technical contacts.

2. Server Info

Server information provides details about the web server hosting the domain. This can include the server’s IP address, hosting provider, geographical location etc.

3. Nameservers

Nameservers are part of the domain’s DNS settings and direct traffic to the correct IP addresses. The tool lists the nameservers associated with the domain, which is crucial for domain name resolution.

The tool also checks if the nameserver supports DNS-over-HTTPS.

4. DNS Records

DNS records are a set of instructions that store information about the domain and are stored on DNS servers. They include various record types such as:

• A Record: Maps a domain to an IPv4 address.
• AAAA Record: Maps the domain to an IPv6 address.
• MX Record: Directs email to an email server.
• CNAME Record: Alias from one name to another.
• TXT Records: Textual information, often used for SPF records and domain verification.

5. Email Configurations

This includes records and settings related to email services such as MX records, SPF, DKIM, and DMARC configurations, which help in authenticating email and preventing spoofing and phishing. For more detailed email configurations checkup, please use our email tool.

6. Website Blacklists

Checks if the domain or associated IP addresses are listed on any blacklists that indicate malicious activity. This is important for maintaining a good reputation and avoiding being flagged by security services.

7. Email Blacklists

Similar to website blacklists, this checks if the domain’s email servers are listed on blacklists, which can affect email deliverability and domain reputation.

8. SSL Certificate

Provides details about the SSL certificate used by the domain, including the issuer, validity period, and encryption strength. SSL certificates are crucial for securing data transferred between the user and the server.

9. HTTP Headers

HTTP headers provide metadata about the website’s responses. This includes information such as content type, server type, caching policies, and security policies.

10. HTTP Security

Evaluates the security of the HTTP headers, checking for implementations of security measures like Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Content-Type-Options.

11. Firewall

Information about any firewall settings or protection measures in place to secure the domain from unauthorized access and attacks.

12. TLS Cipher Suites

Details about the Transport Layer Security (TLS) cipher suites supported by the server. This is critical for securing communications and ensuring the integrity and confidentiality of data.

13. DNSSEC

DNS Security Extensions (DNSSEC) add an extra layer of security to the DNS lookup process, ensuring that the responses to DNS queries are authentic and have not been tampered with.

14. Open Ports

Lists open network ports on the server. This is important for identifying potential security vulnerabilities and ensuring that only necessary services are exposed to the internet.

The following ports are checked:

15. Security.Txt

The security.txt file contains contact information for security researchers to report vulnerabilities. This file helps improve the security of the domain by providing a clear point of contact.

16. Robots.Txt

The robots.txt file provides directives to search engine crawlers about which parts of the site can be crawled and indexed. This is important for SEO and controlling search engine behavior.

17. Archive History

Shows historical snapshots of the website as stored in web archives like the Wayback Machine. This can be useful for understanding the website’s changes over time.

18. Google Cache

Provides information about the most recent cached version of the website by Google, useful for seeing the latest version indexed by the search engine.

Domain Explorer is designed to provide you with comprehensive insights into any domain. It’s very easy to use.

Here’s a step-by-step guide on how the tool works:

1. Enter the Domain Name

   • Simply input the domain name you wish to analyze in the provided search bar. This can be any valid domain name such as itechtics.com. Our tool also works with sub-domains.

2. Initiate the Scan

   • Click on the “Free Scan” button to start the analysis. Domain Explorer will begin fetching a wide range of information related to the domain.

3. Data Collection and Analysis

   • The tool will take a few seconds to collect all the information about the domain.

4. Domain Security Score
   

   We have a domain security scoring system which takes the following information into account:

   • SSL Certificate: The domain must have an SSL certificate installed to ensure encrypted communication.
   • HTTP Security Headers: All critical HTTP security headers (CSP, HSTS, X-Content-Type-Options, etc.) must be configured properly.
   • Firewall: A firewall should be installed and operational to protect against unauthorized access.
   • DNSSEC: DNS Security Extensions should be supported by the DNS server to protect against DNS spoofing and related attacks.
   • Security.Txt: A security.txt file should be deployed to provide a point of contact for security researchers to report vulnerabilities.
   • Blacklist Status: The domain must not be listed on any DNS or email blacklists to maintain a good reputation and ensure email deliverability.

5. Review the Results

   • Once the scan is complete, the tool will display the results in an organized, easy-to-understand format. You can review each section to gain insights into different aspects of the domain.

6. Protect and Optimize

   • Use the insights gained from the tool to enhance your domain’s security, optimize configurations, and ensure compliance with best practices. Address any vulnerabilities or issues highlighted by the tool to protect your domain effectively.

Domain Explorer simplifies the process of domain analysis, providing you with all the necessary information to discover, analyze, and protect your domain comprehensively. DNS security scores help you quickly understand the overall security posture of your domain and identify areas for improvement.

Domain Security Score is a measure of the overall security status of your domain. It considers several factors such as SSL certificate installation, HTTP security headers, firewall status, DNSSEC support, deployment of security.txt, and blacklist status.

You can improve your DNS Security Score by:

• Installing and maintaining an SSL certificate
• Configuring all necessary HTTP security headers
• Ensuring a web application firewall is in place and operational
• Implementing DNSSEC for your domain
• Deploying a security.txt file
• Regularly monitoring and addressing blacklist status

The Domain Explorer tool is completely free to use. There is no limitation (until the server breaks due to overload :-] ). You can use it as much as you can.

There are two types of usage of the Domain Explorer tool:

1. Extract information about a domain
2. Analyze the security status of a domain

It is recommended to use Domain Explorer regularly for analyzing the security, especially after making changes to your domain’s configuration, or if you notice any unusual activity. Regular checks help ensure your domain remains secure and optimized.

While you can copy the report link and share it with anyone you want, Domain Explorer displays results in an easy-to-understand format on the web. Export option may be available in future updates.

No. Our domain checker tool only provides information about public domains. For Active Directory domains, you may run tools like dcdiag on your Domain Controller to check for any issues with AD Domain.

Our Domain Health Check tool can also analyze the health of your web server by examining security headers, SSL certificate status, and other relevant parameters to ensure your website is secure and functioning properly. Make sure your domain security score is 70+.

Although it is possible to check and analyze your domain email configuration and deliverability issues, we strongly recommend using our Email Domain Health Checker tool for detailed analysis of your domain email configuration.
