NetAdmin vs UNetState Pro

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.

------------ [The original of APP] ---------- For the students in the network and computer industry, you will always encounter some network-related problems. For example: You have accessed a service without success. At this time, you need to locate where the problem of the network request is. There are many reasons for a network request failure. For example, your device cannot access the external network, it may be a problem with DNS resolution of the domain name, or the network of the destination host may be down. Then you need a simple and lightweight tool to detect problems. That's why I developed this app. Let me briefly introduce. ------------ 【App Overview】 ---------- 'UNetState Pro' currently provides 9 basic functions, which are: Ping, TCP Ping, UDP Traceroute, ICMP Traceroute, NSLookup, DNS, Port Scan, Scanning LAN Active Devices, Device Network Information. On the settings page, you can set parameters related to the above functions to more comprehensively troubleshoot problems, or you can send us some feedback on this page. 'UNetState Pro' can be installed and used on the current mainstream Iphone and IPad. Therefore, whether you are a student, network engineer, programmer, or network operation and maintenance classmate, this app is very helpful for your study and work! !! !! ------------ [Function description] ---------- 1. Ping: The 'ping' command is mainly used to detect network connectivity and network transmission speed. It uses the ICMP protocol at the bottom. ICMP packets are contained in IP packets. Therefore, the ping command only goes to the IP layer. It can detect the connectivity of the lower three layers of TCP / IP. It does not have the concept of a port. You can set the number of ICMP packets sent in each ping on the app's settings page. 2. TCP Ping: The 'ping' command can basically detect whether one host is connected to another host, but cannot detect whether it is connected to the application layer, and `TCP Ping` just solves this problem, it is a supplement to the ping command. You can set the number of packets and destination port for each TCP ping on the settings page. 3. traceroute: This command is used to view the network routing path of network packets from your device to the destination host. In the implementation based on the UDP protocol, a port greater than 30,000 is usually selected for sending packets, but some host's firewall is in security or other considerations may prohibit UDP detection, so our implementation based on the ICMP protocol is for this situation A supplement. It can still try to find accurate routing information even if the traceroute packet is dropped by the server's firewall policy wall. 4. NSLookup: Parsing domain name use local DNS. . 5. DNS: That is, the user-defined DNS service. Google DNS service: 8.8.8.8 This function module is used by default. You can set up a third-party DNS service on the settings page to parse your domain name. 6. Port Scan: This feature can list whether the ports commonly used by the service you want to probe are available. For example, http default port 80, https default port 443 and other commonly used ports. 7. Scan for active devices in the LAN This function can quickly and accurately scan the IP of all active devices in the LAN. These devices include cell phones, computers, printers, and other networkable devices. 8. Network Information This module can display the cellular network, WIFI network information of your mobile phone, and the external network information of your mobile phone. ------------【other】---------- If you have any better comments or suggestions for this app, you can send us an email through the 'Feedback' function on the settings page, or give us feedback by submitting an issue in the 'Open Source Library'. We will carefully evaluate and continuously update the app. Thank you! !! !! Download it now and experience it!
