Annex C09 Addressing the Network Flashcards
Broadcast Address
Last available IP address in the network range. This address is used to send traffic to all of the devices in the network
Network Address
First availabale IP address in the network range. This address is used to represent the network range and the network as a whole. Also known as the network ID
Host Address
Rest of the IP addresses that fall between the network and the broadcast ID. These are the usable IP addresses that you can assign to devices within the network
Public Address
Designated for use in networks that are accessible on the internet. This means that routers will route these outside of your internal network
Private Address
IP addresses that are designated for use within a private network and must rely on the NAT, to be routable on the internet. Therefore, they do not need to be globally unique
Unicast
P2P comm from one host to another over the network.
Broadcast
Sends IP traffic to the broadcast IP address, all of the computers and network devices on that IP network wil receive the broadcast. One to many
Multicast
When a host sends out a data stream that multiple host can receive. Hosts that receive that data are called multi cast clients, and they subscribe to a multicast group. Multicasting prevents computers from being overwhelmed by connections and also saves bandwidth.
Purpose of a Ping
Used to test whether or not a path through the network exists to a destination network or computer
Network Address Translation (NAT)
Changes the private space addresses in the IPv4 packet header to a public space address.
Internet Protocol Version 6 (IPv6)
Has 8 fields of 4 hexadecimal numbers per field. Larger address space, simpler header which leads to faster and more efficient routing, and built in security.
