Question 1

Dynamic host configuration protocol (DHCP)

Answer 1

4 Step process.
1. Client to DHCP Server– Find all of the available DHCP Servers.
2. Offer - DHCP Server to client– Send some IP address options to the client.
3. Request - Client to DHCP Server– Client chooses an offer and makes a formal request.
4. Acknowledgment - DHCP Server to client– DHCP server sends an acknowledgment to the client.

Question 2

Static

Answer 2

DHCP assigns an IP address from the first available from a large pool of addresses– Your IP address will occasionally change. You may not want your IP address to change– Server, printer, or person. Disable DHCP on the device– Configure the IP address information manually– Requires additional administration. Better: Configure an IP reservation on the DHCP server. Difficult to change later - You must visit the device again. A DHCP reservation is preferable– Change the IP address from the DHCP server.

Question 3

Automatic Private IP Addressing (APIPA)

Answer 3

A link-local address - No forwarding by routers. IETF has reserved 169.254.0.0 through 169.254.255.255. First and last 256 addresses are reserved– Functional block of169.254.1.0 through 169.254.254.255. Automatically assigned– Uses ARP to confirm the address isn’t currently in use.
