A class B network is actually a type of network in the now-defunct classful networking architecture. The classful networking architecture has defined a range of network classes: A, B, C, D, and E as well. Class B networks also have IP addresses between 126.96.36.199 and 188.8.131.52. The Classful networking system has superseded through CIDR (Classless Inter-Domain Routing) since 1993. In this article, we are going to talk about What is Class B Network – Know All About it.
What is Class B Network – Know All About it
Classes A, B, and C provides unicast addresses for networks of three different network sizes actually. Class D was actually for multicast networking and the class E address range was also reserved for future or experimental purposes. IP addresses actually have 32 binary bits of information split into four-octet bytes as well. Class B networks also use the first two octets. And in order to define the network number and also the second octets are used. In order to describe the host addresses available in that network.
Class B networks are defined as in between 184.108.40.206 and 220.127.116.11 actually. In modern CIDR notation, a class network would have the subnet mask /16, and there would be a total of 16,384 possible networks. And 65,536 possible individual host IP addresses per network as well. Before the introduction of the classful networking system, and IP addresses were handed out to companies in blocks that also would become Class A or /8 as well. Given the design of IPv4 addresses, and there can only be 256 class A networks. So the classful system was seen just like a way in order to conserve the available IP address space via handing out smaller networks.
Common Uses of Class B Network
- A Class B network was also a network in which all addresses had the two most-significant bits set to 1 and 0 respectively.
- The pool of unassigned Class B addresses was already rapidly depleted.
- Sixteen contiguous class B networks are actually reserved for private network addresses.
Common Misuses of Class B Network
- Class B networks are actually the second-best, and that they don’t have the same reliability as Class A networks.
