This is a class C address. The network portion is the first
three octets, so it would be 209.240.80.0.
An IP address must be unique within a LAN; the combination of the network and host portion must present a number that is not duplicated anywhere else in the network. Outside of a LAN the IP addresses do not have to be unique, except that the network id portion can only be used by the organization that owns the IP network address. The host portion does not need to be unique across all LANs within an enterprise network.
Here are 3 facts about the network portion of an IPv4 address.Identical for all hosts in a broadcast domainVaries in lengthIs used to forward packets
When you set up a sub network you decide upon the subnet mask and this determines the network address (all zeros in the subnet portion of the address) and the broadcast address (all ones in the subnet portion of the address). When you assign the host addresses in your subnet, then you use the addresses between the network address and the broadcast address.
A network with 6 bits remaining for the host portion can accommodate (2^6 = 64) total addresses. However, two addresses are reserved: one for the network address and one for the broadcast address. Therefore, the number of usable hosts in this network will be (64 - 2 = 62).
A subnet mask can be divided into two sections called the network portion and the host portion. The network portion identifies the specific network to which an IP address belongs, while the host portion identifies the individual device within that network. Together, these sections help determine how IP addresses are allocated and routed within a network.
A slash 22 network, denoted as /22, refers to a subnet mask that allows for 2^(32-22) = 1,024 IP addresses within the network. In a /22 network, the first 22 bits of the IP address are used for the network portion, while the remaining 10 bits are used for host addresses. This means that it can accommodate 1,022 usable host addresses (after accounting for the network and broadcast addresses). Typically, a /22 subnet is used in medium-sized networks requiring a moderate number of IP addresses.
there are two types of addresses: network addresses and physical addresses
The subnet mask for a /26 subnet indicates that the first 26 bits are used for the network portion, leaving 6 bits for the host portion. In this case, the subnet 172.168.2.0/26 can accommodate 2^6 = 64 addresses, but only 62 are usable for hosts (subtracting the network and broadcast addresses). Thus, there are 26 bits designated for the network and 6 bits for hosts within this subnet.
It can provide a list of physical addresses on the network
At Layer 3 of the OSI model, hosts are identified using IP addresses, which provide a unique numerical label for each device on a network. An IP address consists of a network portion, which identifies the specific network, and a host portion, which identifies the individual device within that network. This structure allows routers to efficiently route packets of data between different networks and hosts. Additionally, IPv4 and IPv6 are the two primary versions of IP addresses used in networking today.
