It's a mixed breed rabbit. Frosty (looks to be a bit of darker color on the ear tips and nose so it's not a BEW. Maybe VM frosty if the eyes are bright/ice blue instead of blue gray). At that age new zealand should be about double that weight, they don't come in BEW and it has the wrong fur type. Not a NZ, I'd probably say not even a new zealand cross. Might have dwarf or holland lop in it, but at this point I wouldn't say anything beyond mixed breed for certain
