140xx

The term "140xx" most commonly refers to a range of IP addresses. Specifically, it denotes the Class C subnet range starting with 140.0.0.0 up to 140.255.255.255. In the context of networking, IP addresses are used to identify devices on a network. Class C addresses, historically, were allocated for smaller networks. The 140.x.x.x range has been assigned to various organizations and entities over time for their internal or public-facing networks.

This range can encompass a multitude of individual IP addresses, each capable of being assigned to a specific device. The allocation and management of IP address blocks, including those within the 140.x.x.x range, are overseen by regional internet registries (RIRs) like ARIN, RIPE NCC, APNIC, LACNIC, and AFRINIC. These organizations ensure the efficient and orderly distribution of IP addresses to prevent conflicts and maintain the integrity of the internet's addressing system.

While historically significant in IP addressing schemes, the concept of IP address classes (A, B, C, D, E) has largely been superseded by Classless Inter-Domain Routing (CIDR). CIDR allows for more flexible allocation of IP address space, breaking away from the rigid boundaries of classful addressing. Nevertheless, understanding these older class notations, such as the 140.x.x.x range, is still relevant for comprehending the evolution of internet infrastructure and for interpreting legacy network configurations.
