Claude-Web
Another legacy Anthropic token seen in community registries and older robots.txt files. Not documented on the current Anthropic crawler page; kept here because it is still widely declared and occasionally observed.
Verification
There is no documentation page or IP range list from Anthropic that we can point at for this token.
A user agent is a claim, not a proof: any client can send any name. Where an operator publishes IP ranges, a reverse lookup is the only way to tell a real visit from an impersonation.
