What are two parts that make up network address called?
Network Portion Host 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 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.
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
In bits before subnetting how large is the host portion in a Class A network?
In a class A network, the first 8 bits specify the network, the remaining 24 bits specify the host.
How do you know which bits are host bit in a subnet mask?
Since a subnet mask is used to separate the network id from the host id, any 1 bits indicate the network portion and the 0 bits indicate host portion. As an example, in the subnet mask: 255.255.0.0 This indicates the first two octets are used for the network, and the last two octets (ipV4) are used for host portion of an address.
Which dotted decimal number is used to distinguish the network portion of an IP address from the host portion?
Subnet mask
Which dotted decimal number is used to distinguish the network portion of an ip address from host portion?
subnet masks
What is unique about network IP addresses?
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.
Which value represents the host portion of IP address 128.107.10.11 with a subnet mask of 255.255.0.0?
Seeing as the IP address of 128.107.10.11 is a class B network, the host portion is 10.11
Why do you AND ing the subnet and ip address?
Because this is the way you can easily and quickly isolate the network portion from the host portion of the address to just get the network id, which would be using for routing purposes.
What portion of the IP address 129.219.51.18 represents the network?
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.
