The Institute of Electrical and Electronics Engineers (IEEE) designated by the International Standards Organization (ISO) as the registering body for OUI, which is utilized in the first 3 octets of a MAC address to identify the manufacturer of a network enabled device.
A class C network supports the most networks - the first three octets or 24 bits gives the largest grouping of networks.
IP addresses identify devices on the internet and other TCP/IP networks. They comprise four numbers separated by periods. The first part of an IP address identifies the network, and the last identifies the host. MAC addresses are used only for communication within a local network.There are four octects in a IP address. IP address can be assigned, MAC address are embedded in the (NIC)IP address is a 32 bit address consisting of a series of four 8 bit numbers separated by periods. An IP address identifies a computer, printer, or other device on a TCP/IP network such as the internet or an intranet.Mac address is a unique 42 bit address permanently embedded in a NIC and identifying device on a LAN.Source: CompTIA A+ Guide to Hardware by Jean Andrews (page 468)An IP address is a 32-bit address comprising a series of four 8-bit numbers separated by periods. An IP address identifies a computer, printer or other device on a TCP/IP network such as the internet or intranet.
This is a class C address. The network portion is the first three octets, so it would be 209.240.80.0.
It is a class B address (The first three numbers (octet) are between 128 and 191), meaning it has a subnet of 255.255.0.0, thus, 129.219 is the network portion, with 51.18 representing the host portion.
When we express an IPv4 network address, we add a prefix length to the network address. The prefix length is the number of bits in the address that gives us the network portion. For example, in 172.16.4.0 /24, the /24 is the prefix length - it tells us that the first 24 bits are the network address. This leaves the remaining 8 bits, the last octet, as the host portion.
In the IP address 177.100.18.4, the network portion is determined by the subnet mask. Without knowing the subnet mask, it is impossible to accurately determine the network portion. The network portion is used to identify the specific network to which the IP address belongs, helping in routing and communication between devices.
The purpose of dividing a large TCP/IP address space into multiple smaller networks called sub netting. Each sub network have its own sub net address. The first address of the sub net is the sub net identifier.
Usually the highest address in any given subnet (all 1's in binary) is that networks broadcast address and the lowest address in that same subnet (all 0's in binary) is that networks net-ip (in other words, the address of "the network"). These two addresses are typically never assigned to a host.
