Subnet Plus is a fast, beautiful subnet calculator for network engineers, sysadmins, and students — now completely rebuilt for iPhone and iPad. Type any IPv4 or IPv6 address and instantly see the network address, broadcast, usable host range, subnet mask, wildcard mask, prefix length, total and usable hosts, IP class, and address type. A live prefix stepper lets you dial the mask up or down and watch every value update in real time. NETWORK CALCULATIONS • IPv4 and IPv6, auto-detected • Binary view with network/host bits color-coded • Visual address-space map PRO TOOLS • VLSM Designer — carve a network into right-sized subnets and save the plan • CIDR to subnet mask to wildcard converter • Subnet membership — is an address inside a network? • Range to CIDR, and supernet / aggregate • CIDR cheat sheet NETWORK UTILITIES • DNS Lookup — A, AAAA, MX, NS, TXT, CNAME, SOA, SRV, and reverse PTR — using your device's resolver or any IPv4/IPv6 DNS server you add • Ping — round-trip time and packet loss • Traceroute — see the path to any host • Path Monitor (Pro) — a live, MTR-style traceroute with per-hop packet loss and latency • Network Scanner (Pro) — find the active devices on your local network, their names, and open ports • Email Auth — check a domain's SPF, DKIM, and DMARC records SIRI, WIDGETS & APPLE INTELLIGENCE • Explain this — turn any subnet calculation or Email Auth report into a plain-English explanation, generated on-device by Apple Intelligence • Siri & Shortcuts — calculate a subnet, ping a host, check a port, or ask "What's my network?" by voice, and use the same actions in your own Shortcuts • Live Activities — follow Path Monitor and Network Scanner from the Lock Screen and Dynamic Island • Home Screen widget — pin any saved subnet, with a different subnet per widget SAVE & SYNC • Label and save subnets, VLSM plans, and lookups • Everything syncs across your devices with iCloud • Share and export your results Available in 45 languages.

FREE (6 tools) - Ping — Real-time latency graphs with TCP probes - DNS Lookup — Resolve A, AAAA, MX, TXT records instantly - IP Info — Public IP, geolocation, and network details - Whois — Organization, ISP, ASN, coordinates, reverse DNS, proxy detection - Device Info — CPU, RAM, battery, model, and OS details - Port Check — Scan common ports with service identification BASIC — $9.99/month (11 tools total) - Traceroute — Hop-by-hop path visualization - WiFi Analyzer — Signal strength, channels, and security - HTTP Client — Full request builder with header control - SSL Inspector — Certificate chain and expiry validation - Speed Test — Download, upload, and latency via Cloudflare PRO — $49.99/month (all 16 tools) - JSON Debugger — Tree view, path queries, structural diff, pretty-print, URL fetch, sensitive-key masking - Log Viewer — Live OSLog streaming with multi-level filters, histogram, marking, recording, and export (text, JSON, CSV) - Process Manager — Read-only process tree with ancestors, children, search, and export (macOS) - Scheduled Tasks — Read-only LaunchAgent inspector with decoded schedules and user-granted folder access (macOS) - Security Scanner — 15 sandbox-safe local posture checks (OS version, Gatekeeper, biometrics, code signing, keychain, trust store, volume encryption, and more) plus remote host audit (DNS, port scan, TLS handshake, security headers) BUILT NATIVE No web views. No wrappers. Built on Network.framework, Security.framework, OSLog, and SwiftUI. Every tool runs natively on your device. PRIVACY FIRST No analytics. No tracking. No ads. All tools run locally — nothing about your network, system, or lookups is transmitted to any server operated by ComDeck. HONEST ABOUT THE SANDBOX Some system-level checks (FileVault, firewall, system-wide processes) require admin privileges unavailable to sandboxed apps. ComDeck does not fake these results. The Security Scanner clearly labels which checks are intentionally skipped and why, so the data you see is real. TIER POLICY Higher tiers include all tools from lower tiers.
