TCP/IP Model
- The Network layer provides a route to forward messages through an internetwork
Server Technologies
- DNS servers rely on record types such as A, NS, AAAA, and MX to provide services
- DNS provides hostname-to-IP address resolution services
Network Protocols
- Proprietary protocols are owned and controlled by a single company
Network Configuration
- The
ipconfigcommand can be used on a Windows PC to see the IP configuration of that computer
Networking Models
