Network laboratory · probes, links & passwords
Ask the network.
Watch it answer.
Four instruments in one page. A probe that takes any domain or IP and reports what can actually be learned from a browser — DNS, the registry, round-trip timing, who owns the address block. A global test that asks dozens of real sites across six continents whether the internet is up from where you sit. A shortener that mints permanent labs.llc links. And a password bench with seven ways of generating one.
What it will not do is dress a guess up as a measurement. A browser cannot send ICMP, so the ping here is an HTTPS round trip and says so. 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.

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 round trips, and names the network that answers.
NETLINK probe
Source IP and reverse DNS, A-record resolution, the registry record (registrar, dates, nameservers), five timed HTTPS round trips, 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 about eighty-five major sites, continent by continent, and rates each. The ultra-random sweep shuffles a hundred-site pool and takes fifty — a different fifty, in a different order, every run.
Global probe
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
A short link that stays short forever.
Paste something long and get labs.llc/labluxa/code back — codes start at three characters and grow only when the space fills. Links are permanent 301 redirects with click counting, and go live the instant you make them.
Shortener
Codes are checked for availability before they are claimed, so every link is unique. Nothing is queued — the link is written to this laboratory's own store and redirects the moment it is made.
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.

About
One page, four instruments.
Network Labs folds three LAB properties into one bench: the NETLINK probe and password suite, the global latency laboratory, and the Notime shortener — rebuilt on the labs.llc paper system, in both editions, with the measurements kept honest. The probes run entirely in your browser; the only thing with a server behind it is the shortener, whose links live in the labs.llc store.
