Purpose and properties of IP addressing Flashcards
An____is a 32-bit number that uniquely identifies a host (computer or other device, such as a printer or router) on a TCP/IP network.
IP address
____ are normally expressed in dotted-decimal format, with four numbers separated by periods, such as 192.168.123.132.
IP addresses
Class A address range.
Subnet Mask.
- 0.0.0 - 126.0.0.0
255. 0.0.0

255. 255.255.0.
Class D address range.
Subnet Mask.
224.0.0.0 - 239.0.0.0
Class E address range.
Subnet Mask.
240.0.0.0 - 255.0.0.0
IP Classes:
The first octet is network ID; the last three octets are Host ID. The default subnet mask is 255.0.0.0.
Class A 1.0.0.0 - 126.0.0.0
IP Classes:
The first two octets are network ID; the last three octets are Host ID. The default subnet mask is 255.255.0.0.
Class B 128.0.0.0 - 191.255.0.0
IP Classes:
The first three octets are network ID; the last octet is Host ID. The default subnet mask is 255.255.255.0.
Class C 192.0.0.0 - 223.255.255.0
IP Classes:
Multicasting addresses
Class D 224.0.0.0 - 239.0.0.0
IP Classes:
Experimental use
Class E E 240.0.0.0 - 255.0.0.0
____ IP addresses are globally unique and based on class-based network IDs. When____ are assigned, routes are programmed into the routers of the Internet so that traffic to the assigned public addresses can reach their locations.
Public
____ IP addresses are basically used for host computers that require IP connectivity, but do not need to be visible on the public network. IANA has reserved a certain number of IP addresses for this purpose. ____ addresses are not routable to the public network. Therefore, computers with a ____ IP address connect to the Internet by a proxy server or another Network Address Translation (NAT) device.
Private
Private IP Addresses Classes:
Class A
10.0.0.0- 10.255.255.254
Private IP Addresses Classes:
Class B
172.16.0.0- 172.31.255.254
Private IP Addresses Classes:
Class C
192.168.0.0- 192.168.255.254
____ is a methodology of allocating IP addresses and routing Internet Protocol packets. IP addresses are described as consisting of two groups of bits in the address: the most significant part is the network address which identifies a whole network or subnet and the least significant portion is the host identifier, which specifies a particular host interface on that network.
Classless Inter-Domain Routing (CIDR)
____address is a 32-bit address consisting of a series of four 8-bit numbers separated by periods.
IPv4
____ address is a 128-bit address, which enables it to support a much greater pool of available addresses
IPv6
____ address is a unique 48-bit address assigned to the network interface card (NIC) by the NIC manufacturer.
Media Access Control (MAC)
____addresses alone can’t be used to communicate between two computers on different LANs.
MAC
All hosts on a local area network must communicate by their ____ addresses, which are managed by the Data Link layer protocol that controls the network.
MAC
Unlike other addresses,____ addresses are absolute- a ____ address on a host normally doesn’t change as long as the NIC doesn’t change
MAC
A ____contains six octets in which the first three octets are referred to as Organizationally Unique Identifier (OUI), and the last three octets are referred to as Network Interface Controller (NIC) Specific Identifier.
Media Access Control address (MAC address)
“01:23:45:67:89:ab” is an example of what kind of address?
MAC
____is a process through which an IP address network is divided into smaller networks. It is a hierarchical partitioning of the network address space of an organization into several ____. ____ creates smaller broadcast domains. It helps in the better utilization of the bits in the Host ID. To subnet a network, you take some bits from the host ID and give them to the network ID. As the manager and designer of a network, you have the freedom to do this.
