Most rabbits are actually a mix rather than a specific breed unless you have specifically purchased a certified rabbit. His ears mau be 'lop' or 'upright' but that isnt a breed just a description.
I suggest that you just love and care for him and do not think about whether he is a mix or not.
You say he is a male ? Males are much easier to handle and also to pair up with a friend if they are neutered (castrated) and it is recommended by rabbit welfare organisations that this is done - you can discuss it with your vet when you have the rabbit's vaccinations done if he is not alread vaccinated. Dont forget there are now TWO vaccines needed.
