It would be amazing if you could update for the newer versions of Poxmox!
Thanks!

MAC=$(qm config $1 | grep --color=always "net" | cut -f 2 -d "=" | cut -f 1 -d ",")
echo Found VM_MAC: $MAC
MAC1=$(echo $MAC | cut -f 1 -d ":")
MAC2=$(echo $MAC | cut -f 2 -d ":")
MAC3=$(echo $MAC | cut -f 3 -d ":")
MAC4=$(echo $MAC | cut -f 4 -d ":")
MAC5=$(echo $MAC | cut -f 5 -d ":")
MAC6=$(echo $MAC | cut -f 6 -d ":")
MAC_ADDR=$MAC1:$MAC2:$MAC3:$MAC4:$MAC5:$MAC6
arp -an | grep -i --color=always "$MAC_ADDR"

@Mokarski i would be so grateful if you give me some hints or clarification that could help me understand your script
i am still beginners and i am looking to list all vm ip addresses in my proxmox VE
thanks a lot

@Mokarski i get an error when running this script but it works now after replacing the $ sign with the vmid
is there something that is deprecated or i have to add ??
