WR850
A Dynamic Host Configuration Protocol server dynamically
assigns IP addresses to client hosts on an IP network. DHCP
eliminates the need to manually assign static IP addresses by
"leasing" an IP address and subnet mask to each client. It

The Domain Name System is the Internet system for converting

you access the world-wide web, a DNS server translates the URL
displayed on the browser to the destination website IP address.
The DNS lookup table is a distributed Internet database; no one
DNS server lists all domain name to IP address matches.
A unique name, such as motorola.com, that maps to an IP
