The ifconfig command (when no options or arguments are specified) displays the configuration of all network interfaces.

Your results for defaults show configurations for about 20 distinct interfaces.
I suppose you have some interest in a particular network setting, so it would help to tell us what you want to find out.

Why would you think that was something that you may have done?
When you ran that command, it displays the current configuration of those various network interfaces.
Those are all interfaces that are a native part of your hardware, as reported by the macOS system.
Pretty ordinary, and normal for any computer to show a variety of network settings by default.

Do you have any reason to believe that those settings are anything more than the original settings (from a fresh system install), or are updated settings reflecting whatever use you have for your Mac, and its connection to any network?

"The thing is I didn't do it."
Well, yes, when you connected to a network, Wifi, or hard connected through ethernet, your system automatically responds, and adjusts to that network connection, by modifying settings to allow that network connection. Sometimes it will be completely transparent, no action from you necessary, other than plugging in a cable, or you might enter a password for your wifi connection, or a variety of other actions that you click through for that initial connection. Or, you didn't notice much at all, and your network/internet just worked. But, the network settings (viewable through that same ifconfig) will have been modified.
It's more complex than that, but I think I can safely say this doesn't have anything to do with a VM. Not sure why you mentioned that.

  • lo0 is the loopback virtual interface.
  • en0 is your built-in Wi-Fi.
  • en1 and en2 are your Thunderbolt ports. macOS supports IP over Thunderbolt this way.
  • bridge0 is a virtual interface that bridges your two IP over Thunderbolt interfaces together.
  • en3 is likely an built in ethernet
  • awdl0 is Apple Wireless Direct Link. It's an Apple-proprietary, incompatible equivalent to Wi-Fi Aware or Wi-Fi Direct. It's how AirDrop and AirPlay and Handoff and a few other things work.
  • p2p0 Is like an earlier version of AWDL. When AirDrop first came out and was Mac-only, it used this. iOS never used this and used AWDL instead. Now both platforms prefer AWDL but the older mac-only Apple Peer to Peer wireless protocol still exists for backwards compatibility with older Macs running ancient versions of macOS.
  • utun0 is a tunnel virtual interface used for VPN connections.
  • ipsec0 is also a VPN-related virtual interface.
  • gif0 is a virtual "generic interface" used for certain IPv6-in-IPv4 tunneling situations.
  • stf0 is a virtual interface for an obsolete IPv4/IPv6 transition mechanism known as 6to4 that is still in use by a few people.
  • ap1 is where used Mac as a Virtual Access Point
  • llw is a WLAN low-latency interface likely used with awdlo and ap1
Pretty normal to see on a Mac

He's using an old Linux command in nMac OS with unpinning on BSD Unix! On Mac you should NOT use that command is what I am away, instead use the the command networksetup instead!

ifconfig is 8 years older than Linux and there’s no real reason not to use it like this without arguments, it won’t break anything.

ifconfig is also built into macOS, is it not?
And, the OP was asking about results from the ipconfig command.
Giving an answer about another command would be less than helpful, eh?
(We know nothing about the OP's knowledge level. If you simply want some basic information about the configuration of the network interfaces in your system, ifconfig is competent enough to show that. As someone else said, there's no real reason not to use ifconfig to show the configuration. There is also a man for ifconfig...
