DHCP is the service that automatically gives devices IP addresses and other network settings when they join a network.
Step by Step
- When a device connects, it requests network configuration.
- The router or another DHCP server normally assigns an available local IP address.
- It also supplies settings such as subnet information, gateway, and often DNS servers.
- The assignment is usually leased for a period of time and can later change.
If That Doesn't Work
- Manually assigning addresses inside the DHCP pool can create conflicts.
- Use DHCP reservations when you need a device to consistently receive the same local address and your router supports them.
