Episode notes
DHCP Assigns IP Dynamically
- DHCP assigns an IP address dynamically instead of manual configuration.
- It also provides essential network information for effective communication.
Assign More Than Just IP
- Always assign subnet mask, default gateway, and DNS servers with DHCP.
- These options enable proper TCP/IP networking beyond just the IP address.
DHCP Lease Time Concept
- DHCP assigns addresses with leases limited in time.
- Addresses return to the pool if leases expire without renewal.
