Configure Proxy Using IP Address on macOS

This guide shows how to replace a proxy hostname (DNS) with a raw IP address on macOS — both manually and using a shell script.

This is useful in environments where:

• DNS resolution is unreliable or delayed
• You want to explicitly route through a known egress IP
• You need consistency for proxy-controlled Conditional Access or firewall rules

Manual Method (System Settings)

1. Open System Settings → Network
2. Select your current network (e.g., Wi-Fi or Ethernet)
3. Click Details → Proxies
4. Under:
   • Web Proxy (HTTP) and
   • Secure Web Proxy (HTTPS)
     Replace proxy.company.com with the IP address of the proxy (e.g., 192.168.1.10)
5. Set the port (usually 8080)
6. Click OK and Apply

Scripted Method (Bash)

Use this shell script to apply proxy settings using a raw IP address across all network services:

#!/bin/bash

# Define proxy IP and port
PROXY="192.168.1.10"
PORT="8080"

# Get list of all network services (excluding the header)
services=$(networksetup -listallnetworkservices | tail +2)

# Apply proxy settings to each network service
for service in $services; do
  echo "Setting IP proxy for: $service"
  networksetup -setwebproxy "$service" "$PROXY" "$PORT"
  networksetup -setsecurewebproxy "$service" "$PROXY" "$PORT"
  networksetup -setproxybypassdomains "$service" $(echo $EXCLUSIONS | tr "," " ")
done
