Understand network analysis
Find out what’s going on with your network by using Spotlight to search for and open Network Utility, which offers important tools for diagnosing connections
1 The Info tab
The first tab in Network Utility shows attributes of your connection to your local network and offers basic data transfer statistics. Use the pop-up menu to check details of a different network interface, such as Ethernet or Wi-Fi.
2 The Ping tool
Having trouble connecting to the internet or another device? Enter its IP address or web address in the box at the top of this tab, then click the Ping button. If you see lots of packet errors in the results, that means your connection is timing out.
3 The Lookup tool Want to know more about where communications are coming from? Provide this tool with an IP address and it’ll try to convert it to a domain name – handy if an email header includes the former and you want to know more about its source.
4 The Whois tool
Want to find out who owns a particular website? Type a domain name into the box at the top of the Whois pane for details. This will give you the registration details of the domain, but it’s important to know that many site owners anonymise their information.
