HTTPS Lookup
Our HTTPS Lookup Tool lets you analyze DNS HTTPS records, inspect SSL/TLS certificates, and verify secure HTTP headers to ensure complete HTTPS compliance.
About HTTPS Lookup
HTTPS Lookup Tool: Check DNS HTTPS Records, SSL Certificates & Secure Headers Online
Analyze HTTPS Records and Secure Connection Details Instantly
The HTTPS Lookup Tool by HasheTools helps you inspect both DNS HTTPS records and secure HTTPS response headers for any domain. It allows you to verify SSL/TLS certificate status, encryption strength, and security headers to ensure your website follows modern HTTPS standards and remains protected against vulnerabilities.
What is HTTPS Lookup?
“HTTPS Lookup” can refer to two important checks:
- DNS HTTPS Record Lookup: Verifies the HTTPS records stored in the domain’s DNS configuration, showing how a domain handles secure connections.
- HTTPS Header & SSL Analysis: Examines the website’s HTTPS response headers, SSL certificate details, and encryption configuration.
HasheTools combines both checks into one easy-to-use online tool for complete HTTPS visibility.
1. DNS HTTPS Record Lookup
What Are HTTPS DNS Records?
HTTPS DNS records define how a domain handles encrypted connections and which servers support HTTPS communication. These records are part of the modern DNS setup used to improve security, performance, and encryption management.
How to Lookup HTTPS Records
You can check HTTPS records directly through your terminal or use our online HTTPS Lookup Tool:
Manual Methods:
- On Windows: Native tools don’t support HTTPS record lookup, but you can use WSL or our online tool.
- On macOS:
dig example.com HTTPS
- On Linux:
dig example.com HTTPS
Or simply enter your domain name above to find all HTTPS DNS records instantly using HasheTools.
Example HTTPS Record Output
example.com. 3600 IN HTTPS 1 . alpn="h2" ipv4hint="192.0.2.1"
These records show protocol hints, IP addresses, and encryption parameters for secure HTTPS connections.
2. HTTPS Header & SSL Analysis
Analyze Secure HTTP Headers and SSL Certificates
The HTTPS Lookup tool also lets you analyze HTTPS response headers and SSL/TLS certificates for any website. It verifies encryption status, detects missing security headers, and helps maintain strong HTTPS compliance.
Common HTTPS Response Headers
| Header | Description |
| Strict-Transport-Security (HSTS) | Forces browsers to connect only via HTTPS |
| Content-Security-Policy (CSP) | Prevents XSS and data injection attacks |
| X-Content-Type-Options | Stops MIME-type sniffing |
| X-Frame-Options | Protects against clickjacking |
| Referrer-Policy | Controls how referrer data is shared |
Example HTTPS Header Response
HTTP/2 200
Server: cloudflare
Strict-Transport-Security: max-age=63072000; includeSubDomains
Content-Security-Policy: default-src https:
X-Frame-Options: SAMEORIGIN
Why Use HasheTools HTTPS Lookup?

Frequently Asked Questions About HTTPS Lookup
1. What is an HTTPS DNS record?
An HTTPS DNS record defines how a domain handles encrypted HTTPS connections and provides details like supported protocols, IP hints, and certificate bindings.
2. How do HTTPS headers enhance security?
HTTPS response headers like HSTS and CSP enforce secure browsing and protect users from cross-site attacks and insecure redirections.
3. What’s the difference between HTTP and HTTPS?
HTTPS encrypts the data transferred between the browser and the server using SSL/TLS, ensuring data confidentiality and integrity, unlike HTTP, which sends data in plain text.
4. How can I check my website’s HTTPS configuration?
Simply enter your website URL in HasheTools HTTPS Lookup to analyze both DNS HTTPS records and secure header responses.
