A letter addressing scheme has to do with a TCP/IP protocol. Addresses are determined by both decimal and binary counting.
IPv4
Layer 2 addressing not required for this topology
An example is IPv4 addresses having network, subnetwork, and host portions.

When determining an appropriate addressing scheme for a network, key information includes the size of the network (number of devices), the network's growth potential, and the specific addressing requirements (such as static vs. dynamic IP allocation). Additionally, understanding the types of devices and services that will be used, as well as any subnetting needs for organizational structure or security, is essential. Compliance with addressing standards, such as IPv4 or IPv6, and considering the geographical distribution of devices can also influence the addressing scheme.

Most UNIX implementations use the same type of addressing as other modern Operating Systems, which include page translation, segmentation, and virtual memory addressing.
