These options set the corresponding resolver (name resolution) option flags.
Append "=0" to clear a default option. See man NOEXPAND(resolver(5)) for more

These options temporarily set the corresponding resolver (name resolution)
option flags. Append "=0" to clear a default option. See man
NOEXPAND(resolver(5)) for more information on these options. These flags are
per process, however socat() restores the old values after name resolution.
