What type of address follows a hierarchical format?
mAC ADDRESS its actually network addresses.
Are network addresses used in network routing?
An address that can only be used on the internal network
How many types of addresses does a network node have?
In computer networking, a node refers to a connection point. It has two types of addresses, a network address and a physical address.
Which OSI layer addresses data messages translates logical addresses into actual physical address and routes data to addresses on the network?
Network layer
An isp has a block of 1024 addresses.it needs to be divide the addresses to 1024 customers does it need subnetting?
No. If you have one IP per customer, you don't need to create smaller subnets. (You won't have enough addresses though - the first and last addresses of the block will be the network and broadcast addresses and won't be useable. You'll only have 1022 usable addresses)
Are network layer address physical or logical?
Layer 3 network addresses are logical addresses and can be easily changed by software.
Which IP address class allows for the most network addresses and the least amount of host addresses?
A class C address.
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.
What is the aggregation of IP network addresses advertised as a single classless network address?
Supernetting
A network administrator is building a network for a small business that has 22 hosts the ISP has assigned only one internet routable IP address which IP address block can the network administrator use?
The administrator can set up a Local Area Network (LAN) behind a firewall in which he can assign whatever IP address block he wishes. The firewall and router will then need to be configured to Network Address Translate (NAT) the 'hidden' internal IP addresses used on the LAN to the one assigned by the ISP when network traffic needs to leave the LAN.
Which of the folllowing uses a single public IP address to access the Internet on behalf of all of the hosts on the network that may be using other IP addresses or private IP addresses?
•If the hosts on a network using private IP addresses need to access the Internet, a problem arises because the private IP addresses are not allowed on the Internet. •The solution is to use NAT (Network Address Translation), which uses a single public IP address to access the Internet on behalf of all hosts on the network using other IP addresses.
Is 24 bit block a better addressing scheme in computer networking than a 16 bit block?
There is nothing inherently "better" about the 24-bit block address space. If by "better" you mean "able to contain more addresses," then yes. 24-, 20-, and 16-bit network ranges are also known as class A, B, and C, respectively, and refer to ranges of IP addresses. Every device that directly accesses the internet has a unique IP address. IP addresses are commonly represented as a set of four numbers (called "octets") separated by periods, e.g. "145.94.112.18". Each of the numbers can be in the range of 0-255, and some sets of numbers have special meanings. The range of IP addresses is divided up into three classes based on the first octet. If the first octet is from 0-127 it's class A, 128-191 is class B, and 192-223 is class C. The octets of an IP address are divided up into a network portion and a host portion depending on what class it is. In class A addresses, the first octet is the network portion and the remaining three are the host portion. For class B, it's two-and-two, and for class C the first three are network and the remaining one is host. What does this network/host division mean? Generally, large entities (such as a company) are assigned a single network block of IP addresses. For instance, IBM is in control of the 9.0.0.0 network block. This is a class A address, meaning that the network portion is 9 and the rest is the host portion. IBM can divide this space up (using a technique called subnetting) any way it sees fit. Every computer within IBM would have a different ip in the 9 network, e.g. 9.4.109.10, 9.212.34.88. A class A (or 24-bit) block address has three octets it can use to create different IP addresses, such as "9.0-255.0-255.0-255". A class C (or 16-bit) block address has only one octet it can use to create different IP addresses, such as "192.168.1.0-255". You can clearly see that a class C block address contains less potential addresses than a class A or B block address. This doesn't make class C addresses any worse than class A ones, though. A small business (or a home network) doesn't need a million different IP addresses, so a 16-bit block address is perfect for them and if they had a class A or B all those numbers would be wasted.
