How this page is made
Every number on this page is a measurement Domduck took itself or read from a public source, on a stated date. Nothing here is written by a language model. Where a value has not changed, no sentence is generated about it.
First reading . 5 sources, 6 days with at least one reading. The popularity rank comes from the Tranco list; the registration record from RDAP, which ICANN requires registries to publish. The certificate, the DNS records and the crawler policy are read by Domduck directly from zearn.org.
