Traceroute is an important part of any IT experts toolkit who’s worth his salt.. Traceroute enables you to track down potential routing issues between your Mac/PC/Device to your Router/DNS Servers/Web Host.

If, like me you migrated over to Mac from a PC, you will be used to launching a command prompt and firing off the tracert command. However, in OS X the command is slightly different. Some may say it makes more sense..?

To use OS X Traceroute you need to launch a new terminal session, to do this open Applications > Utilities and click terminal.

When the terminal has launched simply type Traceroute followed by the address you want to trace the route to. So for example, if you wanted to check how your devices browser gets to Google.co.uk you would type:

Traceroute www.google.co.uk

Your mac will then resolve Google.co.uk to it’s IP address, and then trace each ‘hop’ from your device to the address. This can be very handy when trying to figure out if the routing issue is your equipment, your ISP’s equipment or the web host it’s self.
