In what way doesn't it work? This is with my ISP's DNS (using which I can visit https://www.lancaster.ac.uk/ in a browser):

  $ host -t a lancaster.ac.uk
  lancaster.ac.uk has address 148.88.65.80

and this is with Cloudflare's:

  $ host -t a lancaster.ac.uk 1.1.1.1
  Using domain server:
  Name: 1.1.1.1
  Address: 1.1.1.1#53
  Aliases: 
  
  lancaster.ac.uk has address 148.88.65.80

Looks the same to me.
