Q

How does network service order affect network connectivity?

A

The network service order list is used to determine the primary network service interface if more than
one service is active.

All network traffic that isn’t better handled through local connection to an active network service interface is sent to the primary network service interface.

So in most cases, all WAN traffic, Internet traffic, and DNS resolutions are sent through the primary network service interface.

In Network preferences, network service interfaces with a green status indicator are being used for
network activities.

All network traffic that isn’t better handled through a local connection is sent to the primary network service interface.

The primary network service interface is the topmost active interface in the listing.
