How to know the current submask/dns value

[yellowsky]

Hi everyone,
is there any command to know the submask and the DNS which are retreived by DHCP?
Thank you.

nmcli device show eth0

... which works only under linux with the network manager package installed.

Ubuntu has this by default, other distribuitions like SuSE or Debian/Raspian have not.

If you run linux without network manager
use siply "ifconfig" for the network card config.

The configured DNS can be read from a file with "cat /etc(resolv.conf".
Much easier is a " nslookup microsoft com".

Under windows (yes still some peole using it...)
open a cmd window (open start and type "cmd" to get it).
In the cmd windows type "ipconfig /all".
