Dynamic Addressing
Giving addresses to clients (automatically) only when they are logged in to a network
- Eliminates permanent addresses to clients
- When the computer is moved to another location, its new IP address is assigned automatically
- Makes efficient use of IP address space
- Example:
- A small ISP with several thousands subscribers
- Might only need to assign 500 IP addresses to clients at any one time
Uses a server to supply IP addresses to computers whenever the computers connect to network
