Telcoaio - Network Toolbox

Description

A native iOS network engineering toolbox built for engineers, ISP operators, and anyone who needs to debug a connection on the spot.

Native diagnostics run directly on your device. Online features, including Global Ping, speed tests, DNS and registration lookups, contact the relevant services. No account or sign-up required.

NATIVE TOOLS

· Ping — continuous ICMP echo with min / avg / max RTT, loss %, jitter
· Traceroute — hop-by-hop path with per-probe RTT
· MTR — continuous traceroute that combines path discovery with per-hop loss and latency, refreshed every second; 10 packets per probe
· Port Scanner — concurrent TCP connect scan with banner grabbing and service identification
· Service Monitor — save HTTP, HTTPS and TCP endpoints; check status and latency together with optional foreground auto-refresh
· Reverse DNS — IPv4 / IPv6 PTR lookups
· Speed Test — download, upload, and latency via Cloudflare's public speed endpoint
· Global Ping — pings the target from 10 fixed cities around the world (San Jose · Ashburn · Shanghai · Mumbai · Frankfurt · Singapore · São Paulo · Lagos · London · Sydney) with 10 packets each. Powered by globalping.io

DNS & NAMING

· DNS Lookup — A, AAAA, CNAME, MX, NS, TXT, SOA, PTR, CAA, SRV records over DoH or a custom UDP resolver
· DNS Benchmark — find the fastest resolver for you (Cloudflare, Google, Quad9, AliDNS, 114DNS)
· WHOIS / RDAP — domain, IP and ASN registration records

WEB & ADDRESSING

· Subnet Calculator — IPv4 and IPv6 CIDR math, fully offline
· TLS Certificate — chain, expiry, SANs, TLS version and cipher for any host:port
· HTTP Request — status, headers, redirect chain and a DNS/connect/TLS/TTFB timing waterfall
· IPv6 Diagnostics — dual-stack reachability and NAT64/DNS64 detection

INFO TAB

· Current Wi-Fi name (SSID) and BSSID
· Local IPv4 / IPv6, netmask
· External IP, ASN, ISP, country
· Full interface listing with addresses (en0, awdl0, pdp_ip0, etc.)
· Device, OS, screen, memory, storage

LAN TAB

· Local subnet scanner — concurrent ICMP probe with reverse-DNS labels
· Bonjour service browser — HTTP, SSH, SMB, AirPlay, Chromecast, AirDrop, HomeKit, printers, and more
· Wake on LAN — send magic packets to saved devices

EXTRAS

· Visual traceroute — plot the route on a map with per-hop geolocation
· Export — share ping, traceroute, MTR, port-scan and LAN-scan results as text
· Home-screen widget — your public IP and connection type at a glance
· Siri & Shortcuts — Ping a host and get latency and packet loss results

ADDITIONAL ONLINE TOOLS
