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.
What is a Class B IP address example?
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. 226.204, where *168 212* identifies the network and *226.204* helps you identify the Hut network host.

Which IP address should not use in private network?
In April 2012, IANA allocated the block 100.64.0.0/10 (100.64.0.0 to 100.127.255.255, netmask 255.192.0.0) for use in carrier-grade NAT scenarios. This address block should not be used on private networks or on the public Internet.
What part of a Class B IP address identifies the network?
In a Class B network, the first 16 bits are the network part of the address. All Class B networks have their first bit set to 1 and the second bit set to 0. In dotted decimal notation, that makes 128.0. 0.0 to 191.255.
What is class B in networking?
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 The Classful networking system has been superseded by CIDR (Classless Inter-Domain Routing) since 1993.
Which IP addresses are considered to be private addresses?

- Range from 10.0. 0.0 to 10.255. 255.255 a 10.0.
- Range from 172.16. 0.0 to 172.31. 255.255 a 172.16.
- A 192.168. 0.0 to 192.168. 255.255 range, which is a 192.168.

- If it begins with 1111, then it’s a Class E network.
Which address class does not need subnet masks?
A subnet mask is a four-octet number used to identify the network ID portion of a 32-bit IP address. A subnet mask is required on all class-based networks, even on networks that are not subnetted.
Default Subnet Mask.
| IP Address Class | Default Subnet Mask |
|---|---|
| Class A | 255.0.0.0 |
| Class B | 255.255.0.0 |
| Class C | 255.255.255.0 |
What are the 4 types of IP address?
There are four types of IP addresses: public, private, static, and dynamic. An IP address allows information to be sent and received by the correct parties, which means they can also be used to track down a user’s physical location.
Which subnet mask is used with a Class B address?
255.255.0.0
Class B networks use a default subnet mask of 255.255. 0.0 and have 128-191 as their first octet. The address 172.16. 52.63 is a class B address.
What is the subnet mask for a Class B IP address?
255.255.0.0
In comparison to Class A, Class B IP addresses are better suited to serving smaller networks since they reserve 14 bits for a network, which leaves only 18 bits for hosts. Network addresses for these range from 128 to 191. Consequently, the default subnet mask for Class B is 255.255. 0.0.
Why do we need to assign IP?
An IP address is a unique address that identifies a device on the internet or a local network.The internet needs a way to differentiate between different computers, routers, and websites. IP addresses provide a way of doing so and form an essential part of how the internet works.
