Thanks! Yeah, `dig` with no DNS gives me a SERVFAIL but `dig @1.1.1.1` works.

My ISP isn't Vodafone directly (I take it you think that because 83.146.21.6 belongs to them?) but might be a Vodafone reseller or something.

Yeah, I assumed since you were querying their DNS that you were a client, but makes sense it might be repackaged to other ISPs.
