Network configuration made fast.
macOS
OnNet IP Config is a native macOS utility for quickly switching network adapter configurations. Switch between DHCP and static IP in seconds — ideal for IT professionals, developers, and power users who work across multiple network environments such as office, home, VPN, or lab setups. Settings are applied instantly through macOS System Configuration, the same framework used by Network preferences. No restarts required.
Select any adapter — Wi-Fi, Ethernet, Thunderbolt, VPN. Displays BSD name, MAC address, link speed and duplex mode.
Switch between automatic and manual IPv4 configuration with one click. Subnet mask defaults to 255.255.255.0 for manual mode.
Set DNS to automatic or configure preferred and alternate DNS servers manually.
Save named configuration presets. Load, rename, or delete them instantly. Search the profile list as it grows.
Share your full profile set across machines as a portable JSON file. Import multiple profiles in one step.
Real-time view of current IP, subnet mask, gateway, preferred & alternate DNS, DHCP server address, and computer name.
Toggle any adapter on or off directly from the app — no need to open System Settings.
Force a fresh IP lease from the DHCP server with one click when the adapter is in DHCP mode.
Persistent menu bar icon shows the active adapter name and current IP address at all times. Open the app, manage shortcuts, or jump straight to Network Settings.
Register OnNet IP Config as a login item so it's always available from the menu bar when you log in.
OnNet IP Config is a native macOS application built with SwiftUI, distributed directly — no App Store required.

macOS
OnNet is a native macOS network toolkit built entirely with Swift and SwiftUI. It gives you a real-time view of every device on your network, your current Wi-Fi quality, live traffic speeds, and connection-level diagnostics — without ever sending your scan data to the cloud. Everything runs locally on your Mac. Two optional, user-initiated features connect to external services: a public IP lookup (ipinfo.io) to display your current ISP and approximate location, and a Whois Lookup that opens your browser at whatismyip.com for any remote IP in the Active Connections table.
Discovers devices using ARP, mDNS/Bonjour, ICMP and TCP probing. Results stream live as each device is found — no waiting for the scan to finish. Identifies computers, phones, routers, printers, and IoT devices by hostname and vendor OUI. Right-click any device for SSH, HTTP, HTTPS, FTP, Ping, and copy actions.
Lists all local network adapters with IP address, subnet, router, and DNS servers. Shows a live Ethernet speed graph and a per-IP active connections table powered by real-time interface counters. Includes a public IP lookup with ISP, country, city, and VPN/proxy detection via ipinfo.io.
Displays RSSI, SNR, link rate, 802.11 standard (Wi-Fi 4/5/6/7), and channel width. A rolling 2-minute signal history chart shows stability over time. Scans nearby networks to show channel congestion and recommend the least-congested channel for 2.4 GHz, 5 GHz, or 6 GHz.
TCP-based latency probe — sandbox-safe and accurate. Live per-packet output with min/avg/max summary on completion. Built-in port scanner covers 30+ common services (SSH, HTTP, HTTPS, RDP, SMB, DNS, and more) or a custom comma-separated range.
Measures live upload and download throughput directly from network interface counters — no external test server needed. A rolling chart displays the speed history for the current session. Switch between Mbps and MB/s in Options.
Stores the last 100 network scans locally. Select any session to review its full device list. Tracks daily upload and download totals per interface automatically. Export the full traffic history as a CSV file at any time.
Persistent menu bar icon shows live upload and download speeds at a glance. Click to see today's traffic totals broken down by interface. Tap any interface row to jump directly to the relevant tool. All tools are accessible without opening the main window.
Assign a custom name and notes to any device — stored by MAC address so labels survive IP changes. Mark devices as whitelisted to distinguish known from unknown hosts at a glance.
Per-remote-IP traffic table shows upload and download speed and cumulative bytes for the top active connections — available in both the IP Info and Wi-Fi sections. Pause and resume the feed without stopping the monitor. Right-click any row to copy the IP or look it up online.
All scanning and monitoring runs entirely on your Mac. No data is sent to 2DAY Networks Ltd. Two optional user-initiated features connect to external services: a public IP lookup via ipinfo.io, and a Whois Lookup that opens whatismyip.com in your browser. No accounts required. No subscriptions.
