DNS: the internet’s address book
How names become addresses, who sees your lookups, and how encrypted DNS changes that.
- 1 What DNS does
Why computers need a name-to-number lookup for every website you visit, and who actually answers that lookup.
6 dk - 2 Who sees your DNS lookups

6 dk - 3 Encrypted DNS: DoH and DoT
Two standards wrap DNS lookups in encryption. What that actually hides, what it still does not, and how macOS supports it.
7 dk - 4 DNS in attacks and defence
