描述

Hi,

I just installed in my raspberry AdGuard home and so far I'm very satisfied. I just noticed a weird behavior comparing with my previous setup which was using dnsmasq as DNS caching and DHCP server.

I was using expand-hosts option to resolve some local clients using unqualified names instead of their IP. For example, I was able to ping a host using just a simple name (i.e. test) instead of its IP.

When I installed AdGuard I changed my setup of dnsmasq to do only IP-->hostname mapping to my local network hosts and setup accordingly the AdGuard (using the dnsmasq IP as upstream).

While I'm able to ping everything as before (using just a name) from my windows PC I have to add the "." suffix in order to find the host. For example

ping test. instead of ping test

I didn't have to do the same with dnsmasq and I'm wondering why.

Any idea?

Thanks in advance!

研究方向: Investigate why dnsmasq's expand hosts option works with DHCP but AdGuard Home does not forward unqualified names. Check AdGuard Home's upstream DNS configuration and how it handles search domains. Look at the AdGuard Home DNS configuration files and compare with dnsmasq settings.
