I know this might be a little too long, you can completely discard this but DO NOT read part of it and then make such grammarly incorrect and baffling replies.
Maybe I did not clearly state what I was doing, I'll be verbose this time. I'd like to: Connect to a random wifi or ethernet (you can't hard code its dns server, this won't work) with dns poisoning. Define a known domain list that is not poisoned. Connect directly to the dhcp dns for those domains to minimize impact on the local CDN. For those domains that are not in this list, redirect it to another dns server. EDNS is not that good at preserving local CDNs but it's still better than getting bogus results. I was using dnsmasq 2.85 to do all of this, until it is upgraded and no longer works. I'm not quite sure if it is an unintentional feature on the old version 2.85, in option.c there is a piece of clearly intentional code to deal with the sharp inside something like "server=/#/1.1.1.1" if (strcmp(arg, "#") == 0) domain = ""; this also sets the SERV_HAS_DOMAIN server flag below. I remember seeing the feature being discussed in the mailing list, though the thread is not that easy to find. I spent some more time digging into the code base, only to find out that there is no "easy" way to implement this in the new version because of the new sorting algorithm used for choosing servers, the vastly changed server flags (SERV_HAS_DOMAIN, along with some other flags, are removed) and the fact that server flags and query flags are already full, idk if the upstream is willing to merge my changes if the size of the flags are enarged. Worst case I just replace dnsmasq with systemd-networkd, but before that I'd like to know if there's still other ways to implement this. Any help is appreciated.
