Online discussion about Claude access sometimes includes specific claims about exact IP requirements — particular address types being required or disqualifying, specific score thresholds. Worth being clear about which claims are actually grounded in official documentation versus speculation.
What's actually publicly documented
Anthropic publishes general regional availability information — which countries are supported for Claude's consumer and API products. This is the authoritative, verifiable source for availability questions.
What isn't publicly documented
Specific technical requirements about IP address type (residential vs. datacenter vs. VPN), specific reputation score thresholds, or other granular network-level requirements for access are not something Anthropic has published in detail. Claims circulating online about specific thresholds should be treated skeptically rather than as confirmed fact, since they're not verifiable against any official source.
Why this distinction matters
Treating unverified claims as established fact can lead to unnecessary troubleshooting effort chasing a specific "fix" that may not actually reflect how access decisions are made. Grounding troubleshooting in what's actually documented — regional availability, account status, network reachability — is more productive.
What NetRiskScan's checker can and can't tell you
The Claude Access Checker shows your network's observable signals (reachability, apparent region, IP reputation context) — genuinely useful diagnostic information, but not a disclosed set of Anthropic's specific internal access rules, because no such detailed public documentation exists to check against.
FAQ
Where should I look for authoritative information?
Anthropic's own official documentation and support channels are the authoritative source for anything specifically about access requirements — treat other sources, including general online discussion, with appropriate skepticism.
