so i think this is more of an it depends. https://lima-vm.io/docs/config/network/

Thanks Justin, I tried interacting with the configuration with no success; I had not found the doc you shared though. I'll go through the doc and try again.

yeah rd just uses limavm for interacting and maintaining the vm

Typically the bridge network is defined in docker networks though; not sure if Lima is setting those up...

well if you use bridged instead of NAT, but i would assume you are using nat

This has nothing to even do with container networking. The bridge network is used internally as well so for instance; if I have no containers and I only want to pull an image from a registry, it fails to pull if the registry server is on the 172.17 network (which is my case). I need to change the default bridge network so I can pull images.
