HE.NET Network Tools vs iPerf3 Client & Server

This suite of networks tools implements most of the network diagnostics that you need as a Network Engineer or System Administrator. Please help us improve it by giving us feedback. + ARP / NDP: Lookup local devices found on your network using either ARP (IPv4) or NDP (IPv6). + Bonjour Browser: See what DNS-SD/Bonjour services are available on your network + DNS lookup: Search for a servers DNS zone records such as SOA, NS, A, AAAA, MX, PTR. + Interface Information: Get information regarding your device's current network state. + IP Calculator: Calculate the Netmask, Wildcard, Network, Host range, and Broadcast for a given subnet. + iperf: Check bandwidth against remote iperf services. + One Time Password: Securely store and view your TOTP and HOTP (two-factor authentication) codes. TOTP codes are available on the Apple Watch. + Ping: Send ICMP packets to a single IPv4/IPv6 address. + Ping Sweep: Send ICMP packets to an entire subnet range. + Traceroute: Find the route packets take to reach your destination. + Progressive Traceroute: Get detailed statistics for a given route. + Port Scan: Scan a list of TCP ports on any server. + Routing Table: See your local device's routing table. + SSL/TLS Information: Check available ciphers, protocols and what's being used when connecting to a remove service. + Whois: Get information regarding network resources. + NO ADS! Note: Recent iOS releases secure certain low-level network information, and as such will not be available in-app, such as MAC addresses for other network devices.

Requires access to an iPerf3 server (local, VPN, or remote). This is not a general Internet speed test. iPerf3 Client & Server brings the standard iPerf3 tool to iPhone and iPad with a clean, native UI. One purchase also unlocks the Mac version. Measure real throughput across Wi-Fi, cellular, VPN, or LAN. Compare routers and access points, validate ISP or VPN changes, and find bottlenecks. Key features: - Client and server modes - TCP/UDP tests, including bidirectional and reverse - Advanced controls: duration, parallel streams, bandwidth caps, window size, MTU - Shortcuts automation + x-callback-url for power users - Saved server profiles and favorites - History with charts and CSV/JSON export - Detailed metrics: throughput, latency, jitter, packet loss Automate repeatable workflows with Apple Shortcuts or x-callback-url (run tests, fetch results, and chain actions). Built for network engineers, sysadmins, and power users who need accurate, repeatable results.
