Everything that has been through
One page per client. Identification is by User-Agent unless marked verified, which means forward and reverse DNS agreed — a self-declared name is a claim, not a fact, and the difference is marked everywhere it matters.

On “verified”
Any client can send any User-Agent. A row is marked verified only when the connecting address resolves back to a hostname the operator publishes, and that hostname resolves forward to the same address. Everything else is recorded as a claim and displayed as one.
