Too many domain blacklists to be handled by adblock

a blacklist domain contains millions of list for openwrt adblock which is to much to handle by router.Any solution to that?Like in pi hole that uses link that contain domains list to be black instead of actual domain list. I tried to copy and paste that list of domain but it cannot fit because it almost consumes 24mb of memory while I only have 12mb of memory left on my Newifi D2 router.

Maybe you could do something like that with banIP, but I am not sure you'll still manage with that amount of memory.

If you have a router with limited RAM, you need to use a smaller block-list.
