NetDebug Toolkit: Ping & DNS
Network Diagnostics & Analyzer
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
NetDebug Toolkit is the all-in-one network diagnostics suite for developers, sysadmins, IT teams, and power users.
17 pro-grade tools on iPhone, iPad, and Apple TV. Fast. Focused. No account. No tracking.
Diagnose connectivity, DNS, routing, ports, certificates, throughput, and local-network services from one clean interface:
POWER-USER WORKFLOW
• Saved Hosts: store frequently used IPs, hostnames, and MAC addresses with per-host tool defaults
• My Automation: chain multiple tools into one-tap workflows with a combined PDF, PNG, or text run report
• Export & Import: portable JSON files for automations and saved hosts (iOS share sheet, tvOS QR-code download)
• Universal Links & Deeplinks: open any tool from a URL with pre-filled inputs, auto-run, and auto-export, eg. https://netdebug.developerinsider.co/open/ping?target=1.1.1.1&export=pdf
• Copy Deeplink: every tool and saved automation can copy its own shareable Universal Link
• Built-in tool docs: quick-reference markdown for every tool
NETWORK CORE
• Ping: ICMP or HTTP HEAD reachability with timing and packet-loss stats
• Traceroute: hop-by-hop route inspection
• HTTP(S) Check: status, redirect chain, headers, TLS summary
• Speed/Latency Baseline: download/upload presets from 1 MB to 64 MB
• iperf3 Client: TCP throughput against an external iperf3 server (upload or download)
• Public IP + Geo / ASN / ISP: current WAN IP with carrier and location detail
DNS & DOMAIN
• DNS Lookup: forward (host → A/AAAA) and Reverse DNS (IP → PTR), auto-detected from input
• DNS Record Explorer: A, AAAA, CNAME, MX, TXT, NS, SRV via DNS-over-HTTPS (custom resolver supported)
• Whois: RDAP or IANA WHOIS mode, with chained referrals
SECURITY & TLS
• TLS Certificate Inspector: full chain, validity, SANs, signature algorithm, weak-cert signals
• Subnet Calculator: IPv4 and IPv6, usable host range, broadcast, gateway hints
PORTS & CONNECTIVITY
• Port Scan: custom ports or ranges
• TCP/UDP Connect: per-port reachability with built-in UDP profiles (DNS, NTP, SNMP, SIP, RADIUS, TFTP, memcached)
LOCAL NETWORK
• LAN Scan: fast or deep subnet host discovery
• mDNS / Bonjour Browser: AirPlay, HomeKit, Matter, printers, SMB, SSH, and more
• UPnP / NAT-PMP Discovery: router gateway port-mapping introspection
• Wake-on-LAN Sender: send magic packets to wake compatible devices
APPLE TV / tvOS
• Full feature parity: every tool, Saved Hosts, My Automation, and all three in-app purchases ship on Apple TV
• LAN-only QR-code export: Apple TV serves run reports and JSON exports over a one-shot HTTP server; scan the QR with your phone to download
PRIVACY & TRUST
• No account required: Saved Hosts and language preference stay local on device
• No analytics SDK, no behavioural tracking
• Diagnostic traffic only contacts user-specified targets and a small set of well-known, documented endpoints (RDAP, IANA WHOIS, dns.google, ipinfo.io, speed.cloudflare.com)
• All sources of network traffic disclosed in the privacy policy
