   • Open System Preferences → Network.
   • Select your current network connection, click Advanced → Proxies.
   • Enter the proxy IP and port, and select the appropriate protocol (e.g., HTTP, HTTPS).
2. Verify Proxy Effectiveness:
   • Open your browser and visit https://www.whatismyip.com.
   • Check if the displayed IP matches the proxy IP.

Method 2: Use Online IP Checkers

Online IP checkers are a quick way to verify whether a proxy is working. Common tools include:

• WhatIsMyIPAddress
• IPInfo
• IPLocation

Steps:

1. Configure your system or application to use the proxy.
2. Visit any of the above online IP checkers.

• MaxMind GeoIP
• IP2Location
• DB-IP

How to Use:

1. Sign up for the service.
2. Use the provided API or database to query the proxy IP.
3. Verify the returned geolocation information against the proxy provider’s details.

Advantages:

• Provides detailed geolocation information.
• Supports bulk queries, suitable for large-scale verification.

Disadvantages:

• Some services require payment.
• Query speed may be limited by the provider’s API.
