Linux tips: Find the DNS Nameservers (DHCP)

If you're looking for the DNS servers (IP) for your ISP through your working (DHCP) internet connection:

Step 1:

#  cat /var/lib/dhcp/dhclient.leases

Step 2:

(a) Look for your interface's name (e.g: eth0/eth1/wlan0) that's connected to internet

(b) Look under: option domain-name-servers xxx.xxx.xxx.xxx, yyy.yyy.yyy.yyy
