North-south traffic

Which of the following terms is used to describe a traffic flow between devices within the same data center or network?

Automatic Private IP Addressing (APIPA) allows a Windows host to self-configure an IPv4 address and subnet mask when the Dynamic Host Configuration Protocol (DHCP) is unavailable. APIPA uses the address block range from 169.254.0.0 to 169.254.255.255. APIPA-assigned addresses are valid only for communication within the network segment to which a given host is connected; a host with an APIPA-assigned address cannot connect to the Internet.

True

Which RFC describes the concept of private IP addressing?

RFC 1918

Which IPv4 address range is used for loopback addresses?
