Sixteen tools, and what each one actually does

Unprivileged ICMP echo through a native probe, so it is a real ping rather than a TCP connect pretending to be one. Continuous or fixed-count, with adjustable packet size and a running min/avg/max and loss summary.

Walks the TTL up one hop at a time and reads each router's reply out of the socket error queue, naming every hop along the way.

Traceroute and ping combined: it keeps probing every hop and shows where loss actually starts, which a single traceroute cannot tell you.

Measures the line itself against Cloudflare's edge, which answers from wherever is nearest. Reports download, upload, idle latency and jitter — and latency measured while the link is saturated, which is what actually decides whether a video call survives someone else's download.

Speaks the real iperf3 control protocol, so it measures against any standard iperf3 server. Forward and reverse, with per-second throughput as it runs.

Sweeps the subnet with ICMP, falls back to a short TCP probe for hosts that ignore ping, and identifies what it finds using Bonjour, UPnP, WS-Discovery and NetBIOS. Every device opens a detail page with its records and an automatic scan of the ports LAN devices actually listen on. It can also keep watching in the background and notify you when a device you have not seen before joins the network.

Every access point in range with its band, channel, width, security and standard, plus a channel chart showing which parts of the spectrum are crowded and an estimated distance from signal strength.

Full-connect TCP scanning with presets or your own ranges. Distinguishes open from closed from filtered, and reads the banner from services that greet on connect.

Browses the local domain for advertised services and resolves each one to its host, port and TXT records — printers, media players, file shares.

SSDP discovery followed by a fetch of each device description, including the port mappings a router has open.

Both your public IPv4 and IPv6 together rather than whichever answered first, with the geolocation, ISP and AS behind any address you look up.

Queries port 43 directly and follows the referral chain from IANA to the registry that actually holds the record.

Queries any resolver you name — with the common public ones suggested — over plain DNS or DNS-over-HTTPS, with EDNS0 and the TCP retry the standard requires when a reply is truncated.

Network and broadcast addresses, netmask and wildcard, host range and count, class and scope, and subdividing a network into equal subnets.

Checks the hosts you care about on a schedule and posts a notification when one stops answering. The checks run natively, so they keep working with the app closed.

Saved machines, each with its own MAC, broadcast address and port. Sends the magic packet and then polls to confirm the machine actually came up.
