Study Notes

IPv4 Address Assignment Methods

Static Assignment: Manually configured by network administrator
- Requires entering IP address, subnet mask, and default gateway for each host
- Advantages: Useful for devices needing consistent access (printers, servers)
- Disadvantages: Time-consuming, prone to errors
Dynamic Assignment: Uses DHCP (Dynamic Host Configuration Protocol)
- Automatically assigns IPv4 address, subnet mask, default gateway, and other configuration information
- Advantages: Reduces network administrator workload, minimizes errors, allows for address reuse
- Disadvantages: Less control over assigned addresses, requires additional network infrastructure
DHCP Server: Responsible for assigning IP addresses to hosts
- Local PC-based server for medium to large networks
- ISP for home networks
- Wireless router for many home and small business networks, acts as both DHCP client and server

IPv4 Address Types

Static IP Address: Fixed and unchanging, manually assigned
- Advantages: Easy remote access, stability for servers and websites, simpler configuration for port forwarding and network services
- Disadvantages: Requires manual configuration, difficult to manage in large networks
Dynamic IP Address: Automatically assigned by DHCP server, changes periodically
- Advantages: Easier network management, conserves IPs, increases security through regularly changing IP addresses
- Disadvantages: Less predictable for remote access, may require updates if address changes when device restarts or is moved

DHCP Request Process (DORA)

DHCP Discover: Client broadcasts request for IP address
DHCP Offer: DHCP server responds with available IP address, subnet mask, gateway, and other information
DHCP Request: Client selects an offer and sends confirmation to server, declining other offers
DHCP Acknowledgment (DHCPACK): DHCP server confirms IP address assignment, client configures its network interface

Additional DHCP Messages

DHCP NACK (Negative Acknowledgment): Server rejects the request
DHCP Release: Client releases IP address back to server for reuse
