Network Tools vs IP Finder

A network engineer's toolkit that runs entirely on your iPhone. Seventeen tools, no account, no server of ours, and nothing about you collected. THE TOOLS • Ping — ICMP latency and packet loss, with a live chart • Traceroute — the hop-by-hop path, each router named • LAN scan — every device on your subnet, named and identified: routers, NAS boxes, printers, Macs, phones • Port scan — TCP connect scan with banners and service names, from a handful of ports to all 65535 • DNS — your own wire-format resolver: every record type at once, any public resolver you choose, DNS-over-HTTPS, reverse lookups, and a comparison mode that queries five resolvers and flags the one that disagrees • HTTP check — status, redirect chain, the DNS/connect/TLS/TTFB split, security headers • TLS — the full certificate chain, expiry, SANs, cipher suite, and whether the system trusts it • WHOIS — the referral chain followed to the registrar that actually holds the record • Wi-Fi — link quality graded against local thresholds, and a walking survey that compares rooms • Speed test — download, upload, latency and jitter, against Cloudflare or a URL you name • iperf3 — throughput against your own iperf3 server, up or down, multi-stream • IP calculator — CIDR maths, masks, host ranges, binary, and subnet division including VLSM • MAC lookup — 39,000 vendor prefixes, bundled and fully offline • Wake on LAN — the magic packet, sent to every address that might reach a sleeping machine • Network interfaces — addresses, subnets, flags and live throughput • Telnet — a raw TCP terminal for switches, PDUs and console servers • SSH — see below A REAL SSH CLIENT Not a wrapper. The protocol is implemented in Swift, and it does the things you actually need from a phone: • Jump hosts — reach a machine behind one bastion or several, each hop with its own account, its own credential and its own host key to confirm • Port forwarding — bind a local port to a service on the far side, then open it in a browser inside the app: a router's web interface, a database, a dashboard listening only on the server's loopback • scp — send a file up or pull one down, straight to the Files app • ssh-copy-id — put your public key in a server's authorized_keys without a second terminal • Keys — generate ed25519 on the device, or import ed25519, ECDSA and RSA in OpenSSH or PEM form, protected or not. Private keys live in the Keychain and can be exported under a passphrase when you need them elsewhere • Snippets — the commands you always type, one tap above the keyboard • A proper terminal — a real VT/xterm emulator, so vim and htop work, with esc, ctrl, alt, arrows and F-keys on a row of their own

IP Finder shows the public IP address your iPhone or iPad uses on the internet, with the provider and an approximate, IP-based location. It adds a few focused tools to check your connection: IP lookup, live ping, a DNS leak test and a log of IP changes. YOUR PUBLIC IP • Public IPv4 and IPv6 address, internet provider and approximate location • Copy or share the address with one tap • Local network: connection type, local IPv4 and IPv6, subnet mask and DNS servers, as far as iOS provides them IP LOOKUP • Look up any public IPv4 or IPv6 address • Provider, ASN, country, region, city and time zone, with the approximate position on a map LIVE PING • Ping several hosts at once, such as a website, a DNS server or your router • Live latency chart; full statistics (average, jitter, packet loss) with IP Finder Pro • Save targets and share the result as an image DNS LEAK TEST • See which DNS servers answer your device's requests, grouped by country and provider • Useful with a VPN: if your internet provider's DNS servers appear, your DNS requests may be leaving the VPN • Keep a history of past tests IP ADDRESS LOG • Records when your public IP changes, with the network and location at that time • Can also check in the background when iOS allows it • Stored only on your device WIDGETS • Home Screen and Lock Screen widgets with your public IP • Choose IPv4 or IPv6, mask part of the address, and refresh or copy with a tap • Requires IP Finder Pro IP FINDER PRO A one-time purchase, no subscription. Pro removes the daily limits and unlocks the widgets: • Unlimited IP lookups (5 per day without Pro) • Unlimited DNS leak tests (3 per day without Pro) • Up to 5 favorite ping targets (2 without Pro) • Every ping statistic: average, minimum, maximum, jitter and loss • The full IP address log (the last hour without Pro) • Home Screen and Lock Screen widgets GOOD TO KNOW • Location is approximate and based on the IP address. It is not your GPS position. • IP Finder is not a VPN: it does not hide your IP address or change your DNS settings. • No account, no ads, no tracking. Your IP log and history stay on your device.
