Fix for Telemetry DNS Errors (Issue #13272)

Problem

Users experience repeated DNS errors that don't affect core functionality but clutter logs:

Error: getaddrinfo ENOTFOUND http-intake.logs.datadoghq.com

Occurs when Claude Code attempts telemetry connections to Datadog but encounters network restrictions, DNS failures, or connectivity issues.

Solution

Set the CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC environment variable (available since v2.0.17):

Quick Fix

macOS/Linux:

export CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=true

Windows (PowerShell):

$env:CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC = "true"

Windows (CMD):

set CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=true

Permanent Configuration

macOS/Linux - Add to ~/.bashrc, ~/.zshrc, or ~/.profile:

export CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=true

Windows (PowerShell) - Add to your PowerShell profile ($PROFILE):

$env:CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC = "true"

Windows (System) - Set as system environment variable through Windows Settings → System → Advanced → Environment Variables.
