Answer: A subnet mask of 255.255. 255.0 allows for close to 256 unique hosts within the network (since not all 256 IP addresses can be used).This is the default subnet mask used by Class B networks and provides up to 65,536 IP addresses (256 x 256).
What does subnet mask 255.255 255.0 tell the router?
What does the subnet mask 255.255. 255.0 tell a router? The purpose of the part of the mask that reads 255, or all 1s in binary, is to tell a router what part of an IP address is the subnet ID.
What does a subnet mask tell a router?
A subnet mask determines which parts of the IP address are network and host identifiers. It is a 32-bit number that distinguishes each octet in the IP address.
What does the IP address 255.255 255.255 represent quizlet?
255.255 is the broadcast address of a Class B address. This designation means “the broadcast address for this network.” When you are assigning IP addresses to hosts, be aware of the following: Each host must have a unique IP address.
What is the term for the place one network ends and another begins?
When discussing computer networking you’ll often hear the term demarcation point to describe where one network or system ends and another one begins.
Is 255.255 255.255 IP address valid?
No, it is not possible to have any source 255.255. 255.255 as IP Address because this IP Address is already reserved for the broadcast address.
What is a 255.255 254.0 subnet?
255.255.254.0 = 1 bit less than 24 bits mask, so (256 x 2) – 2 hosts = 510. And to know if an ip address is good or not regarding a certain subnet..i do the following: Is 192.168. 1.64 – 255.255.
Is 255.0 255.0 a valid subnet mask?
A subnet mask distinguishes the network identifier from the host identifier in an IP address, but is not restricted by the same rules as the class-based method. A subnet mask, like an IP address, is made up of four numbers. These numbers can range from 0 to 255.0.0 is a valid subnet mask as opposed to 255.0.
What is the purpose of the subnet mask quizlet?
The subnet mask identifies the network and host portion of an IP address. It is used by hosts to identify the destination IP address as either local or remote and is also used by routers to determine the path to route packets.
What is a subnet mask and how is it used quizlet?
Subnet Mask. identifies which bits in the IP address are to be used to represent the network/subnet portion of an IP address.
What is the purpose of an IP address quizlet?
What is a purpose of an IP address? It identifies the source and destination of data packets. You just studied 31 terms!
What is the term for the place one network ends and another begins DMZ subnet demarcation point NAT firewall?
An Internee is where one network ends and another begins.
What is the meaning of router in computer?
A router receives and sends data on computer networks. Routers are sometimes confused with network hubs, modems, or network switches. However, routers can combine the functions of these components, and connect with these devices, to improve Internet access or help create business networks.
What does ARP stand for and what does it do?
Address Resolution Protocol
Address Resolution Protocol (ARP) is a protocol or procedure that connects an ever-changing Internet Protocol (IP) address to a fixed physical machine address, also known as a media access control (MAC) address, in a local-area network (LAN).
What is broadcast in networking?
In computer networking, broadcasting refers to transmitting a packet that will be received by every device on the network.Broadcasting may be performed as all scatter in which each sender performs its own scatter in which the messages are distinct for each receiver, or all broadcast in which they are the same.
What destination adress is 255.255 255.255 for?
broadcast address
255.255. 255.255 Represents the broadcast address, or place to route messages to be sent to every device within a network. 127.0. 0.1 Represents localhost or the loopback address, allowing a device to refer to itself, regardless of what network it is connected to.
How do I know my subnet mask?
Subnets, hosts and broadcast addresses per subnet: To find the valid subnets for this specific subnet mask you have to subtract 248 from the value 256 (256-248=8), which is the first available subnet address.
What should my subnet mask be?
Most home networks use the default subnet mask of 255.255. 255.0.This is the default subnet mask used by Class B networks and provides up to 65,536 IP addresses (256 x 256). The largest Class A networks use a subnet mask of 255.0.
How many IPS does the subnet of 255.255 255.0 have?
254

How long is a subnet mask quizlet?
Subnet masks are always 32 binary digits long.
How many octets does a subnet mask have quizlet?
Subnet IDs are calculated via what’s known as a subnet mask. Just like an IP address, subnet masks are 32-bit numbers that are normally written now as four octets in decimal.
