Assuming we are talking IPv4, the split between network and host is determined by the subnet mask. In binary, where there is a "1" it is network, where there is a "0" it is host. A+ pg. 870: A: 1st octect: Network; 2nd,3rd,and 4th: Host B: 1st and 2nd octects: Network; 3rd and 4th octets:Host C: 1st,2nd,3rd octects:Network; 4th octect: Host

In an IP address, the network and host address portions are identified by the octets. The initial octets correspond to the network address, whereas the later octets signify the host address. The precise division of these octets is dictated by the subnet mask, which determines the size of the network and host portions in the IP address.

Which octets are used for the network address and for host addresses in Class A Class B Class C?
There are 4 octets in an IP address as shown below:Octet1.Octet2.Octet3.Octet4 Every IP class has different allocation of network and host ID.For class A, the network and host IDs' allocation is as follows:Network.Host.Host.HostFor class B, the network and host IDs' allocation is as follows:Network.Network.Host.HostFor class C, the network and host IDs' allocation is as follows:Network.Network.Network.HostYou may go to the following link get more info on IP address classes and their IDs:www.iphow.co.cc
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.
Describe the structure of an ip address?
IP addresses identify devices on the internet and other TCP/IP networks. They comprise four numbers separated by periods. The first part of an IP address identifies the network, and the last identifies the host. MAC addresses are used only for communication within a local network.There are four octects in a IP address. IP address can be assigned, MAC address are embedded in the (NIC)IP address is a 32 bit address consisting of a series of four 8 bit numbers separated by periods. An IP address identifies a computer, printer, or other device on a TCP/IP network such as the internet or an intranet.Mac address is a unique 42 bit address permanently embedded in a NIC and identifying device on a LAN.Source: CompTIA A+ Guide to Hardware by Jean Andrews (page 468)An IP address is a 32-bit address comprising a series of four 8-bit numbers separated by periods. An IP address identifies a computer, printer or other device on a TCP/IP network such as the internet or intranet.
Which portion of the IP address 175.124.35.4 represents the host?
depends on the subnet mask ie/ 255.255.255.252 which would mean 175.124.35.0,4,8,12,16etc etc are networks and 175.124.35.1 & .2 are hosts. .3 is the broadcast address for that subnet.
Because the octets equal to 0 ans 255 are only the numbers 1 through 254 can be used for host information in an IPv4 address?
Because the octets equal to 0 and 255 are reserved
Assuming no subnetting what are valid Class B host addresses?
A classful class B network has a network range of 128 - 191. For host addresses, anything that is legal for an IP address in the last 2 octets would be a valid host address for a class B with no subnets.
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 class B address range?
A class B address range is all the addresses that start with binary 10, or decimal 128-192. As originally defined, the first two bytes (octets) indicate the network; the last two bytes are reserved for the host. That is, a class B network has about 65,000 available addresses.
Which octets are used for the network address and for host address in class A class b class c?

Which IP address class allows for the most network addresses and the least amount of host addresses?
A class C address.
How many host address are there for an address with 21 bits for the network address?
2046 Breakdown: 11111111.11111111.11111000.00000000 /21 - 21 bits in network address represented by ones in binary address above. Leaves 2^11th power host addresses left (the zeros to the right). Equals 2048 host addresses minus the two reserved addresses = 2046

What does the 4 octets in an IP address stand for?
The four octets make up a complete address. The first part refers to a network, the remainder an individual computer in a host; however, the exact size of this "first part" may vary.
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.
What is the maximum number of bits that can be borrowed with class b?
The maximum number of host bits that can be borrowed from a class A address is 22 (technically you could borrow 23 but the resulting network would be useless). A class A address uses 8 bits for its network address and 24 bits for its host addresses. Class A uses a subnet mask of 255.0.0.0 You can only borrow 22 bits (instead of 24) because a valid network requires 4 addresses: A network address, two host addresses and a broadcast address. These networks would result in 30 bits used for the network address and 2 bits used for the host addresses. These networks use a subnet mask of 255.255.255.252
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.
