Network: probe any domain or IP from your own browser

The network
is alive.

The whole console in one page, in both editions. A probe that takes any domain or IP and reports what a browser can actually learn — DNS, the registry, round-trip timing, who owns the address block. A global test across six continents. Short links, reviewed before they resolve. A domain lab that generates names and asks DNS about each one. A password bench, a live news wire, and the sixty-one names for sale.

What it will not do is dress a guess up as a measurement. A browser cannot send ICMP, so the timing here is five HTTPS round trips to Google’s DNS-over-HTTPS resolver, asked about the target — a measure of your own path to that resolver, not of the target. The network path panel is a sketch of a typical route, labelled as a sketch — everything else on the page is measured live, from your connection, at the moment you ask.

Network self-test — UTC

Runs live on every load, against different targets each time. Nothing simulated, nothing cached.

The probe

One target, the whole file.

Give it a domain or an address. It finds your own public IP first, so the path has two ends, then resolves the target, asks the registry for the record, times five HTTPS round trips to Google’s DNS-over-HTTPS resolver, and names the network that owns the target’s address block.

NETLINK probe

Source IP and reverse DNS, A-record resolution, the registry record (registrar, dates, nameservers), five timed HTTPS round trips to Google’s resolver, and the owner of the target's address block.

The global test

Is it you, or is it the internet?

Two sweeps, both real requests from your own connection. The continental sweep works through a fixed roster of seventy-five major sites, continent by continent, and rates each. The ultra-random sweep shuffles a pool of eighty-seven sites and takes fifty — a different fifty, in a different order, every run.

Global probe

Sweep

Each site is resolved over DNS-over-HTTPS, then asked for its front page with a six-second budget. A site that answers is timed; one that does not is reported as unreachable from here — which may be the site, or may be your network. The rating weighs both.

Tiny URLs · made by Click

A short link that shows where it goes.

Paste something long and get labs.llc/click/​code back — a seven-character code made by Click, labs.llc’s link shortener. Whoever opens it sees the full destination and its host first, and presses Continue themselves; nothing redirects. The same address always gets the same link.

Shortener

The address goes to Click on this site when you press Generate, and is checked against Click’s rules first: http and https only, no IP addresses, no other shorteners, and a limit on how many links one address makes in an hour and in a day. Open Click for the full tool and its method.

The password bench

Seven ways to make a password.

Fully random, three words, mnemonic, Markov chains, pronounceable, leet-substituted, or grown from a root word of your own. Everything is drawn from the browser's cryptographic generator and nothing leaves the page — there is no server on the other end of this bench.

The domain lab

Names, made and asked about.

Give it a word — or nothing at all — and it makes ten names across the endings you pick, then asks DNS about each one. A name with records is registered; a name without is probably free, and it is reported exactly that carefully. The full laboratory, with the registries asked directly, is DomainChaos.

Endings

Checked over DNS-over-HTTPS only — quick and free, but DNS is not the registry: a registered name with no records still looks free from here. "Probably free" means exactly that.

The live wire

What the network is talking about.

The front page of Hacker News, fetched live when you ask for it — the fastest honest read of what the technical internet is looking at right now. Every headline links to its discussion.

Domains for sale

Sixty-one names, each with a job in mind.

The sale book, card by card — every name links to an offer email, and the storefront with checkout lives at Buy Domains.

Overview

Internet instruments that run from your own connection.

Network is a bench of internet instruments that run in your browser, from your own connection, at the moment you ask. Give the probe a domain or an IP and it finds your public address and its reverse DNS, resolves the target over Google's DNS-over-HTTPS, asks the RDAP registries — rdap.org first, then IANA and Verisign — for the registrar, dates and nameservers, and names the network that owns the address block. A short self-test runs the same kinds of checks on every load, against targets picked at random.

The global test asks whether a slow page is you or the internet. The continental sweep works through a fixed roster of major sites on six continents; the ultra-random sweep shuffles a larger pool and takes fifty. Each site is resolved over DNS-over-HTTPS, asked for its front page with a six-second budget, then timed or reported unreachable, and the run is rated on both. The domain lab makes ten names and asks DNS about each: a name DNS knows is registered, a name it has never heard of is only probably free. The password bench draws every character from the browser's cryptographic generator, and nothing it makes leaves the page. The live wire is the Hacker News front page, read from the Algolia HN API when you press for it.

What a browser cannot do, the page says. It cannot send ICMP or run a traceroute, so the network-path panel is an illustrative sketch and is labelled as one. DNS is not the registry: the registry-grade name check is DomainChaos. Short links are written to the Network Labs store and are reviewed before they resolve, and the sale book is priced from the same file as Buy Domains.

Reading the results

What each line of a run means.

Source IP is your connection’s public address as api.ipify.org sees it, and Reverse DNS is the name, if any, that Google’s resolver returns for that address — often your provider’s. The A record is the address DNS gives for the target; a site behind a content network may answer with a different one from place to place. The registry block is RDAP, the successor to WHOIS: the registrar, the date the name was created, the date it runs out, and its nameservers.

The owner line names the organisation that holds the target’s address block, read from ipapi.co; for a site behind Cloudflare or a cloud host that is the provider, not the site’s owner. The five round trips time your path to Google’s resolver, so a slow figure there describes your connection and its route to the resolver, whatever the target is.

In a sweep each site’s name is resolved first, then its front page is asked for and timed until the first answer; six seconds without one marks it unreachable from here. The verdict is Excellent at 95 per cent reached with an average under 700 ms, Very good at 88 per cent under 1.1 s, Good at 78 per cent under 1.6 s, Fair at 65 per cent, and Poor below that. Failures on every continent point at your own connection; one continent failing on its own points at its sites, or at the route to them.

About

One page, four instruments.

The Network console rebuilt on the labs.llc paper system, in both editions, with every instrument of the old dark console carried over and the measurements kept honest: the probes, the global tests, working short links, the domain lab, the password bench, the live wire, the sale book and the subscriber card. The probes run entirely in your browser; the short links live in the Network Labs store next door, and the subscriber book is the site's own.
