NetAdmin Pro - Network Scanner
macOS / Utilitaires
NetAdmin is a complete network administration toolkit for your local network. Scan a subnet, see every device that answers, and drill into each host: reachability, round-trip time, open ports, hostname, MAC and vendor. Everything runs on-device — no accounts, nothing to sign up for.
DISCOVER YOUR NETWORK
• Fast subnet ping sweep with a live reachable/latency readout
• Per-host detail: hostname, MAC address, OUI vendor and country, open ports, IPv6 addresses
• Device Identity: on-device brand/model/OS fingerprinting from UPnP/mDNS/hostname/OUI signals
• Bonjour / mDNS service discovery across ~40 service types (AirPlay, HomeKit, printers, file sharing, and more)
• Bluetooth LE device inventory
• Automatic device-type classification and icons
• Rename any host, and add notes and tags that survive re-scans
• Custom scan port list, and CSV export of hosts, Bonjour and Bluetooth results
MONITOR IN REAL TIME
• Live ping-reply latency and packet-loss graphs, per host
• RTT min / avg / max / current / jitter and loss statistics
• Optional automatic re-scan on a schedule you choose
• New-device alerts: get notified when a never-before-seen device joins
• Scan Diff: compare two scans to see which devices were added, removed, or changed
• Digital Presence: person-to-device profiles, who's-home status, and a network event timeline
• SNMP Walk over v1, v2c and v3 (USM authentication + privacy, SHA/AES)
• Module-grouped MIB tree browser with filter and search
• Import your own private MIB files
• Live monitoring: pick numeric OIDs (counters, gauges, timeticks) and graph them over time
• Save walks and export results as TXT or CSV
• Pull the ARP table to auto-fill host MAC addresses
TOOLS HUB
• Subnet Calculator — netmask, wildcard, network, broadcast and usable host range from any CIDR
• DNS Lookup — A, AAAA, MX, TXT, CNAME, PTR, NS, SOA, SRV, CAA, SSHFP records and a DNSSEC indicator
• DNS Benchmark — ranks public DNS resolvers (Cloudflare, Google, Quad9, OpenDNS, AdGuard) by response time
• DHCP Discovery — best-effort enumeration of DHCP servers on your LAN
• Port Checker — test whether a TCP port is open and read its service banner
• HTTP / TLS Inspector — response headers plus certificate common name, issuer, validity and SANs
• Speed Test — 10-second parallel measurement per direction with loaded latency (bufferbloat), an animated gauge, selectable servers (Cloudflare or public LibreSpeed), history and a trend chart
• Security Audit — on-device network security score (A–F) from risky open LAN ports and a router UPnP/IGD exposure audit
• Port Forwards — view, add and remove your router's UPnP port forwards, all on-device
• Wake-on-LAN — save named groups of devices and wake them together
• Topology Map — a visual map of the devices around your gateway
• Wi-Fi Scanner (Mac) — nearby access points via CoreWLAN: SSID, signal, channel, band and security
MORE NETWORK TOOLS
• Traceroute with per-hop geolocation, on-demand WHOIS, and a full-screen map on iPhone
• Ping Test to any host or domain with latency and loss graphs
• Network topology and interface details, public IP, Wi-Fi information
MADE FOR YOUR DEVICES
• Universal three-column layout that adapts from iPhone to iPad to Mac
• Save multiple networks and review them offline
• iCloud sync keeps your saved SNMP servers and bookmarks in step across your devices
• Privacy option to mask the device-specific half of MAC addresses
PRIVACY
NetAdmin works entirely on your device and over your local network — no analytics, no tracking, no third-party SDKs. Location is used only to read the current Wi-Fi name (to label saved networks) and, on Mac, to list nearby access points in the Wi-Fi Scanner; Bluetooth and Local Network access are used only to discover the devices you scan.
Quoi de neuf dans la dernière version ?
SUMMARY TAB
• Network mode opens on a new Summary tab that puts every section on one scrolling page — this device and its interfaces, the active interface and Wi-Fi details, the subnet, connected hosts, the router, your public network and its history, and internet status. of the Network screen.
• Connected Hosts and Network Interfaces show the first eight rows, then a "+N more" row that opens the full list — so the sections below stay reachable.
• The interface list leads with the one actually being scanned, instead of loopback and tunnel devices.
INTERNET STATUS IS NOW MEASURED
• The Internet section used to repeat your public IP and guess "Reachable" from whether that IP was known. It now runs a real reachability check and reports Online or Offline, plus how many outages this device recorded in the last 30 days. No outage or status service is contacted.
FIXES
• ISP details no longer come up blank until you leave the screen and return.
• Tapping the network node you're already on opens its details again.
• The Device Map's network picker no longer wraps mid-word.
