Claude Network & IP Check

Compare Claude exits, supported regions and routing, with optional IPv6, WebRTC and local checks.

Claude network check

Request Cloudflare trace on three Claude domains directly from this browser.

Running the check contacts Claude domains and Cloudflare, which will see your exit IP. The optional network owner lookup also contacts ipwho.is.

Official region lists

Which countries and regions does Claude support?

Read the official source

The current Help Center list was updated on March 16, 2026 and names 176 regions. A newer policy names 185 regions but is marked effective November 12, 2026. Both versions are shown for comparison; check Anthropic’s latest official page for actual availability.

The unlisted examples are not exhaustive. The official policy says regions not listed are unsupported and territories of listed countries generally follow their parent country. Some Ukrainian regions are exceptions that an IP country code cannot distinguish.

Official rules and limits

Network checks cannot verify your account

Anthropic’s official pages govern regional access. An exit country code cannot distinguish the excluded Ukrainian regions or determine an entity’s ownership.
Anthropic also restricts organizations controlled from unsupported regions. A public page cannot check phone numbers, payment methods, account history or organizational eligibility.
If Claude Code runs on a server, in a container or in WSL, check the exit and time zone on that machine. This page observes only the current browser.
IP databases and browser clues are not Anthropic’s internal verdict, so this tool does not invent a success rate or official risk score.

Practical guide

Read Cloudflare trace on three Claude domains from this browser, compare exits, regions and routing, and search the current Help Center and newer policy region lists.

How to use it

Start the check and wait for traces from the three Claude domains and a reference site.
Review the IPs, country codes and consistency, then compare the two official region lists.
Optionally run extended checks for IPv4/IPv6, WebRTC and browser settings, and save an exit locally for later comparison.

Example

If all three Claude domains show one IP while this site shows another, these requests may be split routed. The Claude domains still share the same exit for this run.

What to know

This does not sign in to Claude or call an authenticated API. Cross-origin rules, browser policy and routing may prevent observations. The newer 185-region policy is marked effective November 12, 2026; the current Help Center lists 176. ASN does not reliably classify VPNs or proxies, DNS leaks need a dedicated probe, and results do not guarantee account or API access.

Common question

Why can trace work when Claude sign-in fails?

A trace response shows only that Cloudflare answered this browser request. Account state, service incidents, regional rules and human verification can still affect sign-in.
