Which dotted decimal number is used to distinguish the network portion of an ip address from host portion?
subnet masks
What part of an IPv4 address specifies a particular network interface on the network?
The host portion specifies the particular network interface's address. The network portion specifies the network address.
What are two parts that make up network address called?
Network Portion Host Portion
What portion of the IP address does the prefix represent?
It represents the network portion
How do you know how many bits represent the network portion and 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.
What is the network portion of 177.100.18.4?
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.
What is used to of an IPaddress from the network address separate the host address portion?
To seprate an ip address from the network address we use subnet mask that can seprate the ip address from the network address
When the host portion of an IP address is all binary ones?
The host portion of an IP address of all zeros indicates that you are referring to 'this network'. For example, the address 145.5.0.0 means the network 145.5
What is the difference between a Network address and Broadcast address?
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.
network portion of these addresses: 209.240.80.78?
This is a class C address. The network portion is the first three octets, so it would be 209.240.80.0.
What defines an IPv4 logical network?
Hosts with the same network portion of their IPv4 address.
Does the first portion of each IP address identify the network?
no
