[DOCS] Add `platform.claude.com` to Network Access Requirements allowlist

Documentation Type

Missing documentation (feature not documented)

Documentation Location

https://code.claude.com/docs/en/network-config

Section/Topic

The "Network access requirements" section near the bottom of the page.

Current Documentation

The current list of required URLs is:

Claude Code requires access to the following URLs: api.anthropic.com - Claude API endpoints claude.ai - WebFetch safeguards statsig.anthropic.com - Telemetry and metrics sentry.io - Error reporting

What's Wrong or Missing?

The list omits platform.claude.com.

Recent updates to the authentication flow (specifically noted in v2.1.7) changed the OAuth and API Console URLs from console.anthropic.com to platform.claude.com. Users operating behind strict corporate firewalls or proxies who configure their allowlists based strictly on this documentation will experience authentication failures during the login process.

Suggested Improvement

Please add platform.claude.com to the list of required URLs.

Suggested text:

• api.anthropic.com - Claude API endpoints
• claude.ai - WebFetch safeguards
• platform.claude.com - OAuth and Console authentication
• statsig.anthropic.com - Telemetry and metrics
• sentry.io - Error reporting

Impact

High - Prevents users from using a feature

Additional Context

This is critical for enterprise deployment where all outbound traffic is blocked by default. The omission was identified based on recent changes to the authentication endpoints where the console URL structure was updated. Failing to allowlist this specific domain breaks the claude login flow.
