5-2 Alternate IP Addressing

How do you know if a host is using an APIPA address?

Using APIPA, hosts can assign themselves an IP address on the 169.254.0.0 network (with a mask of 255.255.0.0) if they can't locate a DHCP server.

Which IP configuration parameters are set when APIPA is used? Which parameters are not set?

When a DHCP server fails, APIPA allocates addresses in the private range 169.254.0.1 to 169.254.255.254. Checking against these IP addresses is really the only way to tell. Which IP configuration parameters are set when APIPA is used? Which parameters are not set? As stated in the las question, APIPA sets only the IP and subnet mask addresses and never sets anything else (default gateway or DNS). What are the advantages of static IP address assignments? Reduces DHCP related network traffic; Assigns the same IP address to the same host every time; Disables APIPA which can prevent host connectivity; Usefull when no DHCP servers are available. When might you want to use static IP addressing? You might want to use IP addressing when you are running a fairly small network, and don't want to spend the money setting up a DHCP server. In which scenarios would an alternate IP configuration simplify IP configuration? You can use a DHCP server though multiple routers by allowing BootP requests in the router settings
