X-DNS-Prefetch-Control

This response header controls DNS prefetching, a feature by which browsers proactively perform domain name resolution on links, images, CSS, and other resources the user may navigate to. Prefetching improves performance but can leak information about which resources a page references to the user’s DNS resolver.

See the MDN docs.
