NetAdmin vs NetBuddy DNS Sniffer

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.
