Tools for Technical Professionals
These calculators are built for the daily workflows of developers, sysadmins, and IT professionals. The Subnet Calculator handles CIDR notation and IP range calculations. The Password Generator creates cryptographically strong passwords. Color converters handle HEX, RGB, HSL, and CMYK translations. Each tool is designed to be fast, accurate, and bookmarkable — so you can access it instantly when you need it.
Security and Networking
Network planning starts with proper subnetting — our Subnet Calculator shows network address, broadcast, usable host range, and helps you design efficient IP allocation schemes. For security, the Password Generator creates truly random passwords with configurable length and character sets. Both tools are used daily by IT professionals worldwide.
Frequently Asked Questions
Is the password generator secure?▾
Yes. Passwords are generated entirely in your browser using JavaScript random functions. Nothing is sent to a server. For maximum security, use the generated passwords with a password manager (1Password, Bitwarden) and enable two-factor authentication on all important accounts.
What subnet should I use for a small network?▾
For a typical home or small office (under 50 devices): /24 (255.255.255.0) provides 254 usable addresses — more than enough. For larger networks, /22 provides 1,022 addresses. Use our Subnet Calculator to plan the right size for your network.
