Proxies for Claude — personal IPs for API, Claude Code and web access

Why you need proxies for Claude

Claude is not available in every country, and Anthropic restricts access by region. Even where the service is available, the IP itself matters: the system evaluates its type, reputation and history. Shared and free addresses are used by many users at once — this can trigger additional checks.

This is especially true for developers. Claude Code and the Anthropic API often run from servers, VPS and corporate networks, where the outgoing IP depends on the infrastructure in use. A proxy lets you separate the application's outgoing IP from your main network and use a dedicated IP from the required country.

Important: a proxy solves the IP question, but does not replace the other conditions of using the service (region, payment method, Anthropic rules). Follow them.

Which proxies to choose for Claude

🚀 Personal IPv4 — for API and Claude Code

• Only your IP — the reputation of the address depends on your actions.
• Unlimited traffic and up to 100 Mbit/s. Long sessions and large contexts without slowdowns.
• HTTP/HTTPS and SOCKS5. HTTP/HTTPS for Claude Code, SOCKS5 for scripts and API.
• Country selection. US and Europe.

🛡️ Prime (ISP / Residential or business) — for working with an account

Addresses of real internet providers and business networks. Suitable when you need an address from a real ISP or business network for account work.

❌ What doesn't work

• Free and shared proxies. Such addresses are used by many users at once.
• Public datacenter lists. Used by many people at once, which may trigger additional checks.

How to set up

Option 1: Browser

1. Install the Proxy-solutions settings extension (Chrome, Firefox).
2. Create a profile, choose SOCKS5 or HTTPS.
3. Enter IP, port, login and password.
4. Switch to the profile. All browser traffic will go through the proxy.

Option 2: Anthropic API (Python)

For SOCKS: pip install "httpx[socks]"

import httpx
from anthropic import Anthropic

proxy_url = "socks5://username:password@ip_address:port"

client = Anthropic(
    api_key="your_api_key",
    http_client=httpx.Client(proxy=proxy_url),
)

For high-volume workloads, consider bulk IPv4 proxies to distribute requests across a pool.

Option 3: Claude Code

Linux / macOS:

export HTTPS_PROXY="http://username:password@ip_address:port"
export HTTP_PROXY="http://username:password@ip_address:port"

Windows (PowerShell):

$env:HTTPS_PROXY="http://username:password@ip_address:port"
$env:HTTP_PROXY="http://username:password@ip_address:port"
claude

Use HTTP/HTTPS proxy — SOCKS is not supported in Claude Code.

Common mistakes

• Free and shared proxies. Used by many users at once.
• One IP for multiple accounts. Accounts get linked to each other.
• Jumping geolocation. IP from one country, timezone and language from another raise suspicions. Keep the environment consistent.
• Changing IP mid-session. Sharp switches between addresses and countries look suspicious. Use one static IP.
• SOCKS in Claude Code. Won't work — HTTP/HTTPS is required.

Summary

Personal IPv4 works for API and Claude Code, Prime for account work in the browser. Advantages: personal IPs, unlimited traffic, country selection, 24/7 support.
