In today’s modern networking, we use the TCP/IP suite of protocols for communication that crosses networks. The postal service provides a vehicle for understanding how logical addressing using IP protocol works.
The processes and procedures associated with logical networking as it relates to subnetting and supernetting are beyond the scope of this article.
What is important is that you understand that a portion of an IP address is allocated for both network and host identification. Devices that are located on the same network will be able to communicate effectively at layer 2. Devices that are on different networks will communicate by directing their output data to routers that will be charged with the responsibility of delivery.
When a unit is placed in a mobile home community, it is typically located on a lot (often referred to as a space). The lot address can be used for postal service purposes. As you know, if you want to mail a package from one mobile home to another, serial numbers won’t work. But if you address the package properly, using the format the postal service requires, we have some assurance of delivery.
