Key takeaways
- DNS maps names like dailyscope24.com to IP addresses.
- Your device asks a resolver (ISP, 1.1.1.1, 8.8.8.8, or a company DNS).
- A DNS outage can make the whole web look “down” even if the site is up.
The internet routes packets to numbers. Humans type names. DNS is the lookup. Your laptop asks a resolver; the resolver may ask other servers until it finds a record, then caches it. If the cache is wrong or the resolver is down, apps fail in ways that look like “Wi-Fi is broken.”
Why companies push their own DNS
Filtering, logging, and speed. A school or employer DNS can block categories. A “privacy” DNS can reduce ISP logging and add its own. There is no free lookup with no operator.
