Key terms and descriptions

DNS
Domain Name System maps Fully Qualified Domain Names (F.Q.D.N.) to IP Addresses. DNS allows users to connect to websites using names instead of IPs.
DHCP
Dynamic Host Configuration Protocol automatically leases IP Addresses to clients on the network. DHCP uses UDP and uses ports 67 (server) and 68 (client).
Forward Lookup
A DNS forward lookup provides the IP Addresses for Fully Qualified Domain Names (F.Q.D.N.).
Reverse Lookup
A DNS reverse lookup provides the Fully Qualified Domain Names (F.Q.D.N.) for the IP Addresses.
Zone Transfer
When information is sent from one DNS server to another to provide a list.
