- Scope options can include IP addresses for specific network functions.
- Home or small office DHCP servers may be on embedded routers with different configuration values.
- DHCP assigns dynamic, temporary IP addresses or static, permanent ones based on MAC address.
- Lease times determine how long a device keeps an IP address before checking in with DHCP server.
- T1 timer checks in with DHCP server halfway through the lease time to renew the lease.
- T2 timer allows a device to rebind with another DHCP server if the primary one is unavailable.
