Question

instructions
where are the dns address resolutions stored?

• on your router
• on the host machine
• on your service provider
• all of these

Explanation:

Analyze the question

The question asks: "Where are the DNS address resolutions stored?"

Evaluate the options

• On your router: Routers maintain a local DNS cache to speed up subsequent requests from devices on the local network.
• On the host machine: Operating systems on host machines (like Windows, macOS, or Linux) store DNS resolutions in a local DNS resolver cache.
• On your service provider: Internet Service Providers (ISPs) run DNS recursors that cache DNS query results.
• All of these: Since DNS resolutions are cached at multiple levels (host, router, and ISP) to optimize network performance, this option is correct.

Synthesize the final conclusion

Because DNS caching occurs at the host level, the local network router level, and the ISP level, DNS address resolutions are stored in all of these locations.

Answer:

• On your router
• On the host machine
• On your service provider
• All of these (Correct answer)
