NetDebug Toolkit: Ping & DNS

NetDebug Toolkit is an all-in-one network diagnostics app for developers, sysadmins, network admins, IT teams, and power users who need fast, reliable network visibility.

Diagnose connectivity, routing, DNS, ports, certificates, throughput, and local-network services from one clean interface:
- Ping (ICMP or HTTP HEAD)
- HTTP(S) Check (status, redirect chain, TLS summary)
- Public IP + Geo/ASN
- Speed/Latency Baseline (download/upload presets 1–64 MB)
- iperf3 Client (TCP throughput against an external iperf3 server)
- Subnet Calculator (IPv4/IPv6)
- Traceroute
- Whois (RDAP or IANA WHOIS mode)
- DNS Lookup (custom resolver supported)
- DNS Record Explorer (DoH-based multi-record view)
- TLS Certificate Inspector (chain, validity, SANs, signature)
- Port Scan (custom ports or ranges)
- TCP/UDP Connect (per-port reachability with UDP profiles: DNS, NTP, SNMP, SIP, RADIUS, TFTP, memcached)
- LAN Scan (Fast or Deep)
- mDNS/Bonjour Browser (AirPlay, HomeKit, printers, SMB, SSH, and more)
- UPnP/NAT-PMP Discovery (router/gateway port-mapping introspection)
- Wake-on-LAN Sender

Key capabilities:
- Save frequently used hosts and per-host options for faster troubleshooting
- Optionally disable auto-run on saved hosts when you want to review inputs first
- Reorder saved hosts to match your workflow
