SubnetBuddy vs PeekScout

SubnetBuddy is a fast, offline subnet calculator and network planning tool built for IT professionals, network engineers, students, and anyone studying for their CCNA, CompTIA Network+, or just needs to crunch CIDR notation on the fly. No internet required. No ads. No account needed. Just open the app and start calculating. SUBNET CALCULATOR • Enter any IP address and CIDR prefix (e.g. 192.168.1.0/24) • Instantly see network address, broadcast address, first and last usable host • View total hosts, usable hosts, and wildcard mask • Get the next sequential subnet with one tap • Supports all prefix lengths from /0 to /32 MASK CONVERTER • Convert between CIDR notation, dotted decimal, and binary • Enter a prefix length and see all three formats instantly • Quick-reference for common subnet masks • Perfect for exam prep and on-the-job lookups VLAN PLANNER • Plan multiple VLANs with custom names and sizes • Set a base network and SubnetBuddy calculates non-overlapping subnets for each VLAN • See network range, gateway, CIDR, and host count per VLAN • Great for designing office networks, lab environments, and homework assignments IP VISUALIZER • Enter a CIDR block and see a visual map of the IP address space • Color-coded grid shows used vs. available addresses • Instantly understand how big (or small) your subnet really is • Tap any cell to see the full IP address TERMINAL-STYLE DESIGN • Dark theme with VibeCMD's signature hacker-green aesthetic • Monospace fonts and command-line inspired interface • Clean, distraction-free layout built for speed • Easy on the eyes during late-night study sessions WORKS COMPLETELY OFFLINE • Zero network calls — all calculations happen on-device • No account required — open and use immediately • No data collection — your network plans stay on your phone • Lightning fast — results appear as you type BUILT FOR REAL PEOPLE • IT professionals doing quick subnet math on-site • Students studying for CCNA, Network+, or any networking exam • Homelab enthusiasts planning their network segments • DevOps engineers carving up VPC address spaces • Anyone who's tired of Googling "what is /22 in dotted decimal" SubnetBuddy is a utility tool for network address calculations. It does not connect to or scan any networks.

Hotel anti-spy pinhole camera detection software – an essential privacy guardian for your travels. It integrates high-precision device scanning to thoroughly inspect every corner of the room, quickly identifying and marking potential spying devices. The unique infrared detection technology clearly reveals hidden cameras even in low light, ensuring no blind spots. In addition, the software uses magnetic field intensity detection to capture abnormal magnetic fluctuations, further screening potential threats. Combined with big data intelligent analysis, it pre-marks and warns high-risk areas, providing comprehensive, multi-dimensional privacy protection – so you can enjoy a comfortable stay without worrying about privacy leaks.This app is for assistance only. Detection effectiveness may vary depending on environmental factors, device models, and camera types. It cannot guarantee the discovery of all hidden cameras. Users should always exercise their own judgment to protect their privacy. Featured functions: 1.Device scanning – uses deep scanning algorithms to detect devices on the same network. 2.Device marking – the more people mark a device, the more accurate the data becomes. 3.Infrared scanning – turn off the room lights to directly identify infrared hotspots and locate cameras. 4.Intensity detection – a strong magnetic field exists near cameras, helping to pinpoint their location.
