Does Hosts file override DNS?
Modifying your hosts file enables you to override the domain name system (DNS) for a domain on a specific machine. DNS management is useful when you want to test your site without the test link prior to going live with SSL, verify that an alias site works prior to DNS changes, and for other DNS-related reasons.
How does Dnsmasq work as a DHCP server?
dnsmasq is a lightweight DNS, TFTP, PXE, router advertisement and DHCP server. It is intended to provide coupled DNS and DHCP service to a LAN. Dnsmasq accepts DNS queries and either answers them from a small, local, cache or forwards them to a real, recursive, DNS server. It loads the contents of /etc/hosts…
Do you need Dnsmasq to read / etc / hosts?
Any domain will do, but “localnet” is traditional. Now when you resolve “myhost” the resolver will attempt to look up “myhost.localnet” so you need to have dnsmasq reply to that name. The way to do that is to include the domain in each name on /etc/hosts and/or to use the –expand-hosts and –domain options.
Where do I find the Dnsmasq configuration file?
Its default configuration file is located at /usr/local/etc/dnsmasq.conf and contains examples of its most prominent features. Open that file and add this line all the way at the bottom: This will instruct dnsmasq to include all files that end with .conf in the /usr/local/etc/dnsmasq.d directory as additional configuration files.
What can I use instead of / etc / hosts?
This approach works fine but it’s a bit cumbersome to manage. Mostly because of these reasons: There’s a well-known tool to help us improve host name management: dnsmasq. Dnsmasq is a lightweight DNS forwarder that’s easy to install and configure.
