Aether — Professional Network Intelligence Tools

A clean, sophisticated, single-page PHP application providing three essential professional tools:

• HTTP Status Checker — Deep uptime & response analysis (status, timing, headers, redirects, SSL)
• WHOIS Lookup — Accurate domain registration details via RDAP (primary) + legacy WHOIS fallback
• DNS Inspector — Comprehensive intodns-style analysis (NS, SOA, MX, A/AAAA, SPF, DMARC, DKIM, consistency checks)

Features

• Modern light theme with excellent readability
• Zero dependencies — pure PHP + vanilla JS + Tailwind via CDN
• Works great on restricted shared hosting (DirectAdmin, cPanel, etc.)
• RDAP-first WHOIS (port 443) with legacy socket fallback
• Prominent SPF, DMARC, and DKIM discovery in DNS results
• Beautiful result cards with copy-to-clipboard
• Local browser history (no server-side storage)
• Defensive error handling — always returns clean JSON

Requirements

• PHP 8.0+
• dns_get_record, curl, fsockopen enabled (standard on most hosts)
• Outbound HTTPS access (port 443) — required for RDAP + HTTP checker

Quick Start

Local Development

cd /path/to/aether-network-tools
php -S localhost:8000

Open http://localhost:8000

Production Deployment

Simply upload the entire folder to any PHP-capable web host.

No database, no composer, no configuration.

Recommended for production:

• PHP 8.1+
• Reasonable max_execution_time (12–20s is plenty)
• cURL and dns_get_record enabled

Tool Details

1. HTTP Checker

• Full redirect following + timing breakdown
• TLS certificate details when available
• Complete response headers table
• Status, content type, size, and total time

2. WHOIS / RDAP Lookup

• Prefers modern RDAP (JSON over HTTPS)
• Falls back to traditional WHOIS on port 43 when needed
• Clean parsed fields + full raw response
• Works reliably on shared hosting where port 43 is blocked

3. DNS Inspector

• NS, SOA, A, AAAA, MX, TXT, CNAME, DS, CAA
• Explicit SPF and DMARC extraction
• DKIM discovery via common selectors
• Health & consistency checks (intodns style)
• Overall status (good / warning / error)

Security & Privacy

• Strict input validation on all tools
• No data stored server-side (history is localStorage only)
• All outbound requests use safe timeouts and User-Agents
• Never outputs unsanitized data

Customization

The entire UI lives in index.php.
The three tool engines live in includes/tools/:

• HttpChecker.php
• WhoisTool.php
• DnsInspector.php

You can easily extend or restyle any part.
