[Dnsmasq-discuss] Question about behaviour of '#' symbol

[Elias LA]

Thanks again. I will rephrase my question one last time:

Considering that I have the rule `address=/*.firebaseio.com/`, how can I allow only the domain `firebaseio.com` without having to use the instruction `server=/firebaseio.com/8.8.8.8`? (How can I block all the subdomains except the main domain).

Since you used no-resolv, I guess the request is handled locally according to docs: Also permitted is a -S flag which gives a domain but no IP ad‐ dress; this tells dnsmasq that a domain is local and it may an‐ swer queries from /etc/hosts or DHCP but should never forward queries on that domain to any upstream servers. --local is a synonym for --server to make configuration files clearer in this case. perhaps guys can correct me. >A rephrase of my question is: > > How can I route `firebaseio.com` to resolve using default address (the > standard server defined by `server=8.8.8.8`) without having to write > `server=/firebaseio.com/8.8.8.8` (with keeping the second following rule > `address=/*.firebaseio.com/`). I have said it already: since you send everything to 8.8.8.8 why do you need explicitly configure any domain to query 8.8.8.8 ? Why did you specify that domain at all? Why did you set server= and address= with firebaseio.com? >> > > On 18.03.24 09:41, Elias LA via Dnsmasq-discuss wrote: >> > > >> > > > In mydnsmasq.conffile, I have either one of two sets of rules: >> > > > >> > > > # Set 1: >> > > > >> > > > no-resolv >> > > > server=8.8.8.8 >> > > > >> > > > server=/firebaseio.com/# >> > > > address=/*.firebaseio.com/ >> > > > >> > > > # Set 2: >> > > > >> > > > no-resolv >> > > > server=8.8.8.8 >> > > > >> > > > server=/firebaseio.com/8.8.8.8 >> > > > address=/*.firebaseio.com/ >> > > > >> > > > Running `dig firebaseio.com` using Set 1 gives local address, but using >> > > > `Set 2` give a valid server IP address.
