DNS (Domain Name System)
Networking
The internet’s “phonebook” for website names.
Definition
DNS turns a website name (like example.com) into an IP address so your device can connect.
In plain English
The internet’s “phonebook” for website names.
Why this matters
Why it matters: DNS requests can reveal what sites you’re trying to visit, even if the page itself uses HTTPS.
Example
Example: Your device asks DNS where “bestprivacyapps.com” is located.
