- kadoban 2y agoLooks like once per nameserver that you're configured to use. I guess just in case they give different answers, which is uncommon in practice.
- ksynwa 2y agoWould be useful in my unfortunate case where the ISP's DNS is broken for a bunch of domains. Most notably githubusercontent.com. Also a bunch of CDN domains.

- mrngm 2y agoTry a few queries to an anycasted resolver for the same record. It's rather common that, for example, TTL values differ per response. (the magic trick here is that it's not guaranteed that your requests end up on the same resolver). You could have a look at https://dnsdiag.org/ https://dnsdiag.org/ that provides a few tools for further introspection in the many (different) answers resolvers can give.
- mr-karan 2y agoJust tried on my Adguard DNS server, I am only getting one entry. I think it's related to your nameserver configuration. Could you try reproducing with specifying a custom one, with @1.1.1.1 or something? doggo google.com --short 142.250.185.238
