[Urgent] Macvlan not working

Please can you tell me where I am wrong

sudo docker network create -d macvlan --subnet= --gateway= -o parent=wlan1 pub_net

That’s two post now being ignored

I have bigger problems the whole system has no connecion

and still nothing, so I ended up leaving docker
But I need this setup again

I know I have not had the best record on here. but I really need this sorting
I am sorry about everything that happened before

and nearly two months later, still nothing
I do ideally need pi-hole run in docker with its own static IP address
port 53 is in use on the host system
