How far back does a website go? Type a domain and we ask the Internet Archive for its earliest and latest captures. No account, and the lookup runs from your browser after this page has loaded — the archive can take a few seconds to answer.
An address and a website age differently. An IP address is a rented number: a hosting company hands it back and someone else gets it, so "this address in 2010" is usually a different machine altogether — that history lives in registry records, not in the archive. A domain keeps its name, which is exactly why the archive is useful for it: the earliest capture is close to when the site went up, and comparing captures shows what changed.
The archive only holds pages that someone chose to save — a crawl, a library, an owner. A missing year means nothing was captured, not that the site did not exist. Dates and snapshots belong to the Internet Archive; we only point at them.
For the address itself, see our IP pages, the country and network indexes, or the network tools for DNS, HTTP and TLS checks.
