✨ Key Features & Tool Suite

📡 IPv4 Subnetting & CIDR Engine

• IPv4 Subnet Calculator: Calculates Network Address, Broadcast, Usable Range, Mask, Wildcard, Block Size, and Usable Hosts (/0 to /32). Includes real-time 32-bit binary octet visualization.
• CIDR Aggregator & Supernetting: Aggregates contiguous CIDR blocks into optimized supernets and detects sub-network overlaps.
• VLSM Calculator (Variable Length Subnet Masking): Generates optimal subnet allocations ranked by host capacity with interactive space utilization bars and preset scenarios (Enterprise Branch Office, AWS VPC 3-Tier).
• IP Range-to-CIDR Converter: Takes any Start & End IPv4 address span and derives the minimal exact set of matching CIDR subnets.
• Wildcard Mask & Cisco ACL Generator: Converts subnet masks to inverse wildcard masks and generates copyable Cisco IOS Standard & Extended ACL syntax (access-list 100 permit ip ...).

🔄 Multi-Format Converters & IPv6 Suite

• Universal Cross-Converter: Instant multi-way conversion across Dotted Decimal IPv4, 32-Bit Binary, Hexadecimal, 32-Bit Unsigned Integer, Octal, and IPv6-Mapped IPv4.
• IPv6 Calculator & RFC 5952 Engine: Zero-compression/expansion, syntax validation, SLAAC EUI-64 Link-Local IPv6 generation (fe80::...), and multicast scope inspection.
• MAC Address Tools: Normalizes MAC strings across IEEE Colon (00:11:22:33:44:55), Hyphen (00-11-22-33-44-55), and Cisco Dot (0011.2233.4455) formats, extracts OUI, checks Unicast/Multicast, and calculates SLAAC IPv6 addresses.

📚 Integrated Searchable Reference Databases

• Port Reference Database: Instant filtering across common TCP/UDP service ports (FTP, SSH, DNS, HTTPS, BGP, WireGuard, etc.).
• IP Protocol Reference: OSI layer transport protocol matrix (ICMP, IGMP, TCP, UDP, GRE, ESP, OSPF).
• CIDR Cheat Sheet Table: Complete matrix from /0 through /32 displaying mask, wildcard, total capacity, usable hosts, and block sizes.
• Subnetting Architectural Guides: Visual cheat sheet cards for quick network design reference.

🚀 Productivity & UX Capabilities

• Export Data: One-click export of Subnet, CIDR, and VLSM calculations as structured JSON, CSV, or TSV text files.
• Global Search (Ctrl + K): Modal search index to launch any of the 22 tools instantly.
• Offline First & Zero Latency: Pure client-side JavaScript bitwise math—runs locally without internet connection or API keys.
• Dark/Light Mode & History: Theme switcher with localStorage persistence and calculation history log.
