What is a class B network?
What is a class B network?
A class B network is a type of network in the now-defunct classful networking architecture. Class B networks have IP addresses between 128.0. 0.0 and 191.255. 255.255. The Classful networking system has been superseded by CIDR (Classless Inter-Domain Routing) since 1993.
What does class B contain?
Explanation: Each block in class B contains 216 addresses.
What is the range for class B private network?
Class B: 172.16. 0.0 to 172.31. 255.255.
How many hosts are in a class B network?
Table 2-1 IP Addresses Available to Internet Hosts
| Address Class | First Octet Range | Number of Hosts Per Network |
|---|---|---|
| Class A | 0 to 126 | 16,777,214 |
| Class B | 128 to 191 | 65,534 |
| Class C | 192 to 223 | 254 |
How do I find my class B IP address?
You can do it by looking at the first octet of the IP address. Convert the dotted-decimal IP address to its binary equivalent. If it begins with 0, then it’s a Class A network. If it begins with 10, then it’s a Class B network.
What is a valid Class B host address?
In a Class B address, the host bits are the third and fourth octets by default. 255.254 is the last valid host. 152.93. 255.255 is the broadcast address (all host bits on).
What is a Class B IP address?
Class B IP addresses are used for medium and large-sized networks in enterprises and organizations. They support up to 65,000 hosts on 16,000 individual networks. Class C addresses are most common and used in small business and home networks. These support up to 256 hosts on each of 2 million networks.
Which of the following is an example of a Class B IP address?
Class B Network The first 16 bits (known as two octets) help you identify the network. The other remaining 16 bits indicate the host within the network. An example of Class B IP address is 168.212. 226
How do you calculate the number of hosts in Class B?
With those two addresses always reserved, the total number of assignable hosts for a class B network is 216 – 2 = 65,534. The total number of networks a class address may have is calculated by subtracting the number of bits in the subnet mask from the number of bits used to determine which class of network it is.
How do I assign a Class B IP address?
Class B Network Numbers A class B network number uses 16 bits for the network number and 16 bits for host numbers. The first byte of a class B network number is in the range 128-191. In the number 129.144. 50.56, the first two bytes, 129.144, are assigned by the InterNIC, and comprise the network address.
What is the purpose of Class B?
How is a Class B network address assigned?
The last two bytes, 50.56, make up the host address, and are assigned at the discretion of the owner of the network number. Figure 3-3 graphically illustrates a class B address. Class B is typically assigned to organizations with many hosts on their networks. Class C network numbers use 24 bits for the network number and 8 bits for host numbers.
What is the maximum Class C network number?
Class C network numbers are appropriate for networks with few hosts–the maximum being 254. A class C network number occupies the first three bytes of an IP address. Only the fourth byte is assigned at the discretion of the network owners.
What makes up a Class A network number?
A class A network number uses the first eight bits of the IP address as its “network part.” The remaining 24 bits comprise the host part of the IP address, as illustrated in Figure 3-2 below.
How many bits does a Class B address use?
Figure 3-3 graphically illustrates a class B address. Class B is typically assigned to organizations with many hosts on their networks. Class C network numbers use 24 bits for the network number and 8 bits for host numbers. Class C network numbers are appropriate for networks with few hosts–the maximum being 254.
