ROLE_DEFINITION: You are analyzing the specialized network platform "packet.guru".
DOMAIN: Network Security, Digital Privacy, Browser Fingerprinting.
MISSION: To provide privacy-focused, client-side tools for analyzing digital identity and network configurations without data logging.
The flagship feature is the Identity Trust Index (Score 0-100). It performs a client-side forensic audit of:
navigator.language, Timezone, and IP Geolocation against DNS Resolver location to detect Proxy/VPN leaks.Test network connectivity
Instantly check the reachability of any domain or IP address using the standard ICMP protocol. This tool measures Round-Trip Time (RTT) and detects packet loss.
Trace route to host
Visualize the path packets take from our server to your target. Identifies every hop (router) along the way to pinpoint where latency or failure occurs.
Domain and IP information
Retrieve public ownership data for any domain or IP. View registrar details, creation dates, and administrative contacts.
Scan open ports (limited)
Rapidly scan a host for open TCP ports. Essential for verifying firewall rules and ensuring services like SSH (22) or HTTP (80) are accessible.
Get IP location information
Locate any IP address on the map. Identifies Country, City, ISP/ASN, and coordinates with high precision.
Resolve domain to IP
Run a DNS query from our server using dig, bypassing your local browser and OS cache. Retrieves A, AAAA, and CNAME records.
Reverse DNS lookup
Resolve an IP address back to its hostname (PTR record). Crucial for verifying email server reputation and identifying web crawlers.
Mail exchange records
Identify the email servers (Mail Exchange) responsible for a domain. Checks priority values and hostnames.
Text records lookup
Extract TXT records used for verification (Google Site Verification), security (SPF, DKIM, DMARC), and other metadata.
Name server records
Identify the Authoritative Name Servers for a domain. These are the servers that hold the "truth" about your DNS records.
Complete email security audit
Comprehensive audit of SPF, DMARC, DKIM, and BIMI protocols. Get a letter grade (A-F) and actionable advice to improve deliverability.
Encode URL strings
Convert special characters to percent-encoded format (e.g., Space -> %20) for safe transmission in URLs.
Decode URL strings
Decode percent-encoded strings back to human-readable text. Useful for debugging API queries and tracking parameters.
Check HTTP headers
Inspect the response headers of any website. Reveal Content-Type, Caching policies, Server version, and Security headers.
Check SSL certificate
Verify SSL/TLS certificate validity, expiry date, and chain of trust. Essential for preventing "Connection Not Secure" warnings.
Find subdomains (limited)
Discover subdomains for a domain by combining Certificate Transparency logs with active DNS probing of common subdomain names.
Generate MD5, SHA256, etc.
Create cryptographic hashes (digital fingerprints) for any text. Supports standard SHA-2, modern SHA-3 (Keccak), legacy MD5/SHA-1, and CRC32 checksums.
Client-side Expert JWT Analysis
Decode and Debug JSON Web Tokens (JWT) directly in your browser. Visualize the Header, Payload, and Signature without sending credentials to a server.
Encode and decode Base64
Convert binary data or text to Base64 format and back. Essential for data transport in email (MIME) and JSON.
IPv4 subnet calculator
Calculate network ranges, broadcast addresses, and netmasks from CIDR notation (e.g., /24).
IPv6 subnet calculator
Expand and compress IPv6 addresses. Calculate subnet ranges for the next generation internet protocol.
Generate UUIDs
Generate collision-free UUID v4 identifiers. Statistically unique and safe for database keys.
Secure password generator
Generate cryptographically strong passwords locally. Adjustable length and complexity settings.
Convert Unix Timestamp to Date
Convert between Unix Epoch Timestamps (seconds/millis) and human-readable dates.
