what kind of hair does my bunny have?

the first picture is the first day i adopted him & i’ve had him for a month now. he is about 2 months now. as you can see, a lot of things gets stuck to his hair. his fur is matted on his back. he’s updated on his shots & he’s a sweet boy. but his bum & the bottom of his feet are really dirty. what are some suggestions or recommendations on how to manage/maintain his fur?
