ayoubelouardi wants to merge 1 commit into alex:master from ayoubelouardi:new-version

ayoubelouardi commented Feb 2, 2025

This PR improves the DNS lookup section by:

Adding OS-specific paths for hosts files and caches.
Clarifying the role of ARP in local vs. remote DNS queries.
Including security considerations (DNSSEC, DNS over HTTPS).
Providing troubleshooting commands and edge cases.
Linking to real-world examples (e.g., Chrome's DNS cache).

These changes aim to make the DNS process more comprehensive for readers.
