What is the preferred way to determine the subnet mask of your box using /bin/ip on debian 9.0 (stretch)?
In the old days, this sort of information would come out of ifconfig, but it looks like debian really wants to get away from ifconfig, and i think use ip as a sort of replacement. So i would like to do the same thing, using ip or whatever the debian people think is the best practice. I tried to search for this information using google, but not very skillfully. TIA for any info. dan
