[Dnsmasq-discuss] server priority clarification after e86d53c
dave14305 via Dnsmasq-discuss · 2026-04-22 · via dnsmasq-discuss
Since v2.92test5, commit e86d53c ("Fix some edge cases wth domains and 
--address and --server.") clarifies the priority order of competing address and 
server options for the same domain:

--address with a IPv4 or IPv6 address (as long as the query matches the type)
--address with # for all-zeros, as long as the query is A or AAAA)
--address with no address, which returns NXDOMAIN or NOERROR for all types.
--server with address set to # to use the unqualified servers.
--server with matching domain.
--server without domain or from /etc/resolv.conf.

In light of this priority, I am seeing unexpected behavior when using server 
and local for adblocking with whitelisting. The local entry would be part of a 
downloaded adblocking list and the server entry would be a local whitelisting 
attempt.

Example:
server=/googleads.g.doubleclick.com/#
local=/googleads.g.doubleclick.com/

With this config, I would expect a query for googleads.g.doubleclick.com to be 
allowed since --server with # should take priority, but instead it is blocked. 
Example is from April 9 while I waited to be approved for the mailing list.

# dig googleads.g.doubleclick.com. @127.0.0.1
