I've been trying to ssh to a raspberry pi with a 32 gigs sd card with no progress. I've been using raspberry pi imager for a while with other 16 gigs sd's on other pi zero w with expected results. This is the first time that i use a 32 gigs sd card. The sd card have been formatted by me to be a fat32 file system and i deleted all the partitions it had before. I'm doing the ssh headless and I'm installing raspberry pi OS lite (32 bit).

When I'm done installing the image, I see that everything is correct and that there is data inside the card, but for some reason every time that I use arp -a in my main computer after powering on the raspberry pi, I never see a proper MAC address with it's proper IP address.

I was expecting to see the beginning of the raspberry Mac address something like this 'b8:27:eb:...' and it's corresponding IP with no luck.

  • You NEED a monitor to setup Raspberry Pi OS. What does it show on screen?

  • @Milliways you categorically don't. If you follow the documention you can have headless without needing to have graphical access. OP - I'd suggest using the link above to set this up rather than the installer you mentioned in your original post on SO

  • not all pi's use b8:27:eb: ... also, don't forget, the first boot resizes the root partition, which can take some time on an sd card Jul 3, 2023 at 0:08
  • @JaromandaX early RPis use b8:27:eb:xx:xx:xx modern ones use d8:3a:dd:xx:xx:xx.

  • @Dougie - yes, I did say NOT all use b8:27:eb - mine is a DC:A6:32 so, your comment seems to be no 100% correct Dec 2, 2023 at 2:26

As far as I can see, the 32GB is not the issue, it looks more like a network thing.

Pi's can have different MAC ID's. As far as I know:


is the current list of vendor IDs assigned to the Raspberry Pi Foundation.

Alternatively, you can edit avahi.conf and un-comment the line

#allow-interfaces=<interface name> 

and uncomment the line


(and perhaps give it a creative hostname)

Using mDNS, you should be able to reach the Pi as raspberrypi.local.
