Network Tools
Free, in-browser tools to inspect, test and configure your home network. No installs, no tracking.
Discovery & identity
IP Reachability Test
Confirm whether 192.168.1.1 — or any IP — actually answers from this device. 4 methods, instant result.
What Is My IP
Public & local IPs, browser fingerprint, connection details — all in real time.
Browser Ping
Send probes to an IP and chart the round-trip latency. Same technique as the reachability tester, but timed.
Local Port Scanner
Scan common ports on a LAN host from your own browser. Live progress, no install.
Network analysis
Subnet Calculator
CIDR → network, broadcast, host range, binary mask. Visual split into sub-networks. All offline.
IP Converter
Convert an IPv4 address between dotted, decimal, hex and binary in real time.
DNS Lookup
Resolve any hostname using DNS-over-HTTPS. Choose Cloudflare, Google or Quad9.
MAC Vendor Lookup
Paste any MAC address — we'll identify the manufacturer using the IEEE OUI registry.
