Module 1 – 5c Network Addressing
Network Address
-
Protocols vary according to the purpose, speed, transmission efficiency, utilization of resources,
ease of setup, compatibility, and ability to travel between different Local Area Network (LAN)
TCP/IP developed by DoD
Flexibility allows it to run on virtually any combination of network OS or network media
Transmission Control Protocol (TCP)
-
Reliable data delivery services
Connection must be established between communicating node before data is transmitted
Internet Protocol
-
Responsible for logical addressing
IP address identifies both host and residing network of each machine
Assigned manually or automatically through service such as Dynamic Host Configuration
Protocol (DHCP)
Network Address
-
Designation used in routing to send packets to remote network
IP Address
-
Logical address used to define a single host (device) on network
Network + Host
Broadcast Address
-
Address used by applications and host to send information to all network nodes
Host/Device/Node
-
Any connected network device (computer, router, printer, etc.)
IP address
-
-
Can be IPv4 or IPv6
IPv4 annotated as Dotted decimal
o Ex. 172.16.30.5
o Consist of 32 bits
IPv6 annotated as 8 groups of four hexadecimal digits
o Ex. 2001:0db8:85a3:0000:0000:8a2e:0370:7334
o 128 bits divided into 8
Module 1 – 5c Network Addressing
Network Address
-
Also known as Network ID
Designation used in routing to send packets to remote network
Uniquely identifies each network
Connect multiple LANs into WANs with use of routers
Every machine on the same network shares that network address as part of its own IP host
address
Network Classes
Class A – (Range 1 – 126) /8 255.0.0.0
Class B – (Range 128 – 191) /16 255.255.0.0
Class C – (Range 192 – 233) /24 255.255.255.0
Class D – (Range 224 – 239) used only for multicasting
Class E – (Range 240 – 254) experimental use only
Network Subnet Mask
-
Way to partition networks into logical segments or groups for easier administration
