Please Whitelist This Site?
| IP Address Class | Total # Of Bits For Network ID / Host ID | # Of Host IDs Per Network ID |
|---|---|---|
| Class A | 8 / 24 | 224-2 = 16,277,214 |
| Class B | 16 / 16 | 216-2 = 65,534 |
| Class C | 24 / 8 | 28-2 = 254 |
What are the 4 classes of IP?
IP address classes With an IPv4 IP address, there are five classes of available IP ranges: Class A, Class B, Class C, Class D and Class E, while only A, B, and C are commonly used. Each class allows for a range of valid IP addresses, shown in the following table. Supports 16 million hosts on each of 127 networks.
Which class has no ID and host ID?
Class D
Explanation: Class D is the multicast address class. It does not have Net ID and Host ID fields.
What is the net ID in Class A?
If the class is class A, the first byte is the netid and the remaining 3 bytes are the hostid. If the class is class B, the first 2 bytes are the netid and the remaining 2 bytes are the hostid. For a class C address, the first 3 bytes are the netid and the last byte is the hostid.
How do I find my net ID and host ID?
A host ID can be found simply by ANDing the IP address in binary form with its respective default subnet mask (in binary form). The other fragment of an IP address is the network ID, which identifies the network to which the host belongs. For Example, In the above Image, the IP address of host C is 198.162.
What is a Class C network used for?
Classes of IP Addresses
| Class | Purpose |
|---|---|
| A | These are designed to be used in very large companies like Google. |
| B | These are designed to be used in medium-sized companies |
| C | They designed to be used in small-sized companies. |
| D | They are not used in the public sector, instead being reserved for multicast addressing |
How many classes are in network?
What are the classes of networks? There are five classes of subnetworks: Class A, Class B, Class C, Class D, and Class E. Each class relates to a specific range of IP addresses. Classes A, B, and C are used the most often by different networks.
What is the difference between Class A and Class B IP addresses?
If the address is written in decimal format, the first number determines the address. If the first number is between 0 and 127 inclusive, the address is class A. If the first number is between 128 and 191 inclusive, the address is class B.
Who uses Class A IP?
Internet Service Providers
Class A IP addresses are used for huge networks, like those deployed by Internet Service Providers (ISPs). Class A IP addresses support up to 16 million hosts (hosts are devices that connect to a network (computers, servers, switches, routers, printers…etc.)
How do I know my IP class?
You can identify the class of an IP address by looking at its first octet. Following are the ranges of Class A, B, and C Internet addresses, each with an example address: Class A networks use a default subnet mask of 255.0. 0.0 and have 0-127 as their first octet.
How to determine the network and host ID of Class B?
For determining the Network and Host ID: We know that Subnet Mask for Class A is 8, for Class B is 16 and for Class C is 24 whereas Class D and E are not divided into Network and Host ID. For 2nd Example, the first octet is 130. So, it belongs to Class B. Class B has a subnet mask of 16.
Which subnet class does the host ID belong to?
So, it belongs to Class B. Class B has a subnet mask of 16. So, the first 16 bit or first two octets are the Network ID part and the rest is the Host ID part.
What is the difference between Network ID and host ID?
Looking now at Host A, you will see that its IP Address is 192.168.0.2. The Network ID portion of this IP Address is in blue, while the Host ID is in orange. I suppose the next question someone would ask is: How do I figure out which portion of the IP Address is the Network ID and which is the Host ID?
How many bits are in a Class A network ID?
Any Class A network has a total of 7 bits for the Network ID (bit 8 is always set to 0) and 24 bits for the Host ID. Now all we need to do is calculate how much 7 bits is:
