### Added

|
||||
- New flag `--no-etc-hosts` to disable client domain name lookups in the
|
||||
operating system's /etc/hosts files ([#1947]).
|
||||
- The ability to set up custom upstreams to resolve PTR queries for local
|
||||
addresses and to disable the automatic resolving of clients' addresses
|

([#2704]).
