DNS Relay

Computer users usually prefer to use text names for computers they may want to open a connection with. Computers themselves, require 32 bit IP addresses.
Somewhere, a database of network devices' text names and their corresponding IP addresses must be maintained.
The Domain Name System (DNS) is used to map names to IP addresses throughout the Internet and has been adapted for use within intranets.
For two DNS servers to communicate across different subnets, the DNS Relay of the Switch must be used.The DNS servers are identified by IP addresses.

count to determine whether to forward a given BOOTP or DHCP packet.
