DNS over HTTPS. It allows encrypted DNS lookup with a URL, which allows for url-based customizations not possible with traditional DNS lookups (e.g. the server could have /ads or /trackers endpoints so you can choose what to block).
DNS Over TLS (DoT) is similar, but it doesn’t use URLs, just IP addresses like generic DNS. Both are encrypted.
