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.Host
For class B, the network and host IDs' allocation is as follows:
Network.Network.Host.Host
For class C, the network and host IDs' allocation is as follows:
Network.Network.Network.Host

What is the network portion of 177.100.18.4?
This is a class C address. The network portion is the first three octets, so it would be 209.240.80.0.
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.
What is ip address format?
Just a little caveat here, what Archangel dmitry lists here is true but should be regarded as only historical information since classed IP address assignment has not been used in over 20 years. It was replaced in 1993 by Classless Inter-Domain Routing. This was put in place to help deal with the quick depletion of available public IP addresses. In the modern day, IP addresses are assigned as needed rather than as blocks as was done when classed addressing was used.
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.
How Many Classes in internet protocal address?
IP addresses are divided into five IP classes:IP address class AIP address class BIP address class CIP address class DIP address class E
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.
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.
How many octets does a Class A address use for network identification?
the answer should be B
