A class B network is a type of network in the now-defunct classful networking architecture. The classful networking architecture defined a range of network classes: A, B, C, D and E. 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 The Classful networking system has been superseded by CIDR (Classless Inter-Domain Routing) since 1993.
