What is DNS over HTTPS?

DNS over HTTPS encrypts the lookups that turn a domain name into an address, so they cannot be read or altered in transit:

• It protects the question, not the destination - the site you visit is still visible by other means.
• Browsers may use it by default - which can bypass filtering you have set at the network level.
• It is mostly a client-side matter - there is nothing for a small business to publish on its own domain.

Worth knowing if you rely on DNS-based content filtering, because the browser may be routing around it.
