## Overview

This hub focuses on the practical network checks that often happen together when a request, endpoint, or packet trace looks wrong. It brings together packet-capture inspection, webhook replay and signature checks, CIDR and address validation, DNS and WHOIS lookups, hosts-file editing, SSL endpoint checks, and user-agent parsing so users can move from raw traffic evidence to a more concrete diagnosis without jumping across unrelated tools.

## Tools

- Network Packet Analyzer: Parse pcap and basic pcapng captures, surface protocol hierarchy and session statistics, and export filtered packet summaries
- Webhook Debugger & Relay: Generate a unique webhook capture URL, inspect incoming requests, validate signatures, and replay payloads to a target endpoint
- CIDR Calculator: Calculate network information from CIDR notation. Supports IPv4 and IPv6.
- DNS Query Tool: Query DNS records and domain resolution information including A, AAAA, MX, TXT, NS, and CNAME records
- WHOIS Lookup: Query WHOIS domain registration information including registrar, dates, and name servers
- Hosts File Editor: Parse, validate, and format hosts file entries
- IP Address Validator: Validate IPv4 and IPv6 addresses with CIDR notation support
- IP Address Extractor: Extract IPv4 and IPv6 addresses from log files, server logs, network traces, or any text content
- MAC Address Validator: Validate MAC addresses and identify vendor information
- User-Agent Parser: Parse and analyze User-Agent strings to extract browser, operating system, device, and engine information
- SSL Checker: Check SSL certificate information, validity, and security configuration
- IPv4 to Integer: Convert IPv4 addresses to integers. Supports batch conversion of multiple addresses.
- Integer to IPv4: Convert integers to IPv4 addresses. Supports batch conversion of multiple integers.

- MAC Address Samples: Collection of MAC addresses in various formats for validation testing
- User Agent Samples: Comprehensive collection of User Agent strings from various browsers, operating systems, devices, and bots for testing and validation
- Network Security and SSL/TLS Configuration: Comprehensive network security examples including SSL/TLS configuration, firewall rules, VPN setup, and network scanning protection

## Frequently asked questions

### What can this hub help with?

It helps with packet-capture inspection, webhook replay and validation, CIDR and IP checks, DNS and WHOIS lookups, hosts-file review, SSL endpoint checks, and user-agent analysis.

### Who is this hub for?

It is useful for backend developers, SREs, DevOps teams, security engineers, API teams, support engineers, and anyone debugging network or endpoint behavior.

### Where should I start?

Start from the evidence you already have. If you have a capture file, inspect packets first. If you have a failing endpoint or callback, check DNS, SSL, headers, webhook replay, and address validation next.
