If you’re using a Mac and you want to speed up your internet connection, then Network Utility is the tool for you. This powerful little program can help optimize your network settings and improve your online experience.
What is Network Utility?
Network Utility is a built-in tool on Mac that allows you to view and modify your network settings. With this program, you can change your DNS server, configure IP addresses, and troubleshoot connection problems.
The Network Utility app is a graphical user interface for several macOS networking Terminal commands, such as netstat, ping, lookup, traceroute, and so on. This program is designed for users who are unfamiliar with the macOS terminal commands.
Network Utility is also a great way to speed up your internet connection by optimizing your network settings.
Update: Network Utility Deprecated in macOS Big Sur
Network Utility provided information and troubleshooting tools to help users check their network connection, view routing tables, trace network traffic paths, check for open TCP ports, and more. Since the release of macOS Mojave, the app had been rather hidden under System > Library > CoreServices > Applications.
Network Utility’s functionality can still be replicated with Terminal commands, and for WiFi issues, Apple says to use the Wireless Diagnostics app.
