IP Addressing and Subnet Quick Review (N10-008) (22)
Exam Prep
1. RFC1918: Defined the 3 ranges of private IPv4 Addresses
10.0.0.0 - 10.255.255.255 /8
172.16.0.0 - 172.31.255.255 /16
192.168.0.0 - 192.168.255.255 /32
2. Network Address Translation (NAT): Translates the private IP address to a public address
for routing over the Internet
3. Port Address Translation (PAT): A port number is tracked with the client com- puter's private
address when translating to a public address
4. APIPA (Automatic Private IP Addressing): A service that enables a DHCP client
computer to configure itself automatically with an IP
address on the 169.254.0.0
network in case no DHCP servers respond to the client's DHCP discover broadcast.
5. EUI-64 (Extended unique identifier): used with IPv6 addressing. EUI-64 pro- vides a mechanism
for logical assignment of the host's MAC address in the interface ID of the host'sIPv6 address
6. Multicast: a form of transmission in which a message is delivered to a group of hosts interested in
receiving data. Bad for large scale networks
7. Unicast: a message that is sent from a single sender to a single recipient
8. Anycast: A method of addressing groups of computers as though they were a single computer.
Anycasting starts by giving a number of computers (or clusters of computers) the same IP address.
