Domain Name Service (DNS) is a system which translates the meaningful Hostnames and Domain Names into valid IP Addresses. A DNS Client or a Resolver is a host or a network device which queries the DNS servers for various resource records like the IP Address for a host like a Mail Server.

HowTo: Change Default Gateway or Default Router in Sun Solaris
The Default Gateway or the Default Router is the IP address (IPv4) to which all the traffic to any target destination(s) which does not have a route in the Routing Table of the server will be forwarded.
This Default Gateway is maintained in the file
/etc/defaultrouter [IPv4 only]
Disable IP Forwarding in Solaris Operating System
IP packet forwarding is the process of routing packets between network interfaces on one system. A packet arriving on one network interface and addressed to a host on a different network is forwarded to the appropriate interface. While this is a job for the network router, Servers with multiple interfaces connected to different network can perform this action as well. This behaviour as a router is a default in Sun Solaris Operating Systems.
