Many home routers can resolve starting from root or if you must then: 1.1.1.1, 8.8.8.8, 8.8.4.4 will get you started. You might consider 9.9.9.9 and there are quite a few others.
I never, ever, ever, recommend using ISP provided DNS unless you know how they are configured. The anycast jobbies at least publish a policy of some sort.
