What else can I help you with?
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 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 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.
What portion of an IP address consists of from one to three octets with the final octet between 1 and 254?
network
Which part of an IP address identifies a specific device on a network?
the host portion or the last part
How many bits comprise the network portion of a class c address?
Thirty bits make up the network portion of a class C address. Three bits are borrowed for the subnet mask. There is also a class A and a class B that are comprised of bits.
What constitutesthe serial number portion of the MAC address?
The serial number portion of a MAC address is typically represented by the last three bytes (24 bits) of the address. In a standard MAC address, which is usually formatted as six groups of two hexadecimal digits (e.g., 00:1A:2B:3C:4D:5E), the first three bytes (the Organizationally Unique Identifier or OUI) identify the manufacturer, while the last three bytes serve as a unique identifier assigned by the manufacturer to each network interface card (NIC). This ensures that each device has a unique MAC address within its network.
How does the IP address indicate the network?
The first octet determines what class of network you are located on. From that, you can determine how many of the octets represent the network address, and which part represents the client or host portion. IP addresses in version 4 (iPv4) are divided into two segments: the network id and the host id. Knowing the range of network class addresses will help: Class A is 0 - 126 and uses only the first octet for the network portion Class B is 128 - 191 and uses the first two octets for the network id Class C is 192 - 223 and uses the first three octets for the network id An example would be: 192.168.1.5 is a class C address, so we use the first three octets for the network id. This gives a network id of 192.168.1.0 and a host id of 5 in that network.
What is true regarding network layer addressing?
The three correct options are: 3. Hierarchical Explanation: By design, layer three addressing is hierarchical, as you can group hosts in different networks. 4. Uniquely identifies each host Explanation: Each host has a unique address inside its network. 6. Contains a network portion Explanation: For example, in an IP (v4) address a portion of the most significant bits identify the network the host belongs to.1.It supports data communications between networks 2.It prevents broadcasts 3.It uniquely identifies each host
What is network id host id?
Network IDA network ID refers to a part of a TCP/IP address that is used to identify the subnet that a host may be on. The subnet that the computer is on is determined by the netmask and IP address of the computer. This subnet address is the same as the network ID and is the beginning part of the computers IP address.When the netmask is setup, it is a number where some of the most significant bits have a 1's value and the rest have values of 0. The most significant part of the netmask with bits set to 1's specifies the network address, and the lower part of the address will specify the host address.The part of the IP address that matches the part of the netmask where the bits are set to ones determines the network ID.
What part of 192.168.10.51 is the Network ID assuming a default subnet mask?
Assuming a default subnet mask of 255.255.255.0 for the IP address 192.168.10.51, the Network ID is 192.168.10.0. The first three octets (192.168.10) represent the network portion, while the last octet (51) identifies the specific host within that network. Thus, the Network ID indicates the entire subnet where the host resides.
A network uses a subnet mask of 255.255.255.0 and has a computer on the network with the IP address of 120.12.12.3 Will the IP address 120.12.12.3 be on the network Explain your answer?
No, because first three octets are suppose to be same and they are not.
