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).
there are two types of addresses: network addresses and physical addresses
It can provide a list of physical addresses on the network

One - by your problem statement, all addresses are part of the same network. The number of host addresses is 232-21 - 2, or about 2000.One - by your problem statement, all addresses are part of the same network.

What is one purpose of using logical addresses in an IP network?
Layer 3 network addresses are logical addresses and can be easily changed by software.
