Your ISP probably has a Class C address. D 224–247 These are reserved for multicasting (transmitting different data on the same channel). E 248–255 Reserved for experimental use. These five classes of networks will become more important later in this book (or should you decide to study networking on a deeper level). 4 carefully, and you probably will discover that the IP range of 127 was not listed. This omission is because that range is reserved for testing. 1 designates the machine you are on, regardless of that machine’s assigned IP address.

Does your approach help guarantee the integrity of data? And does your approach still make the data readily available to authorized users? Another important concept to keep in mind is least privileges. This means that each user or service running on your network should have the least number of privileges/access required to do her job. No one should be granted access to anything unless it is absolutely required for the job. ” Network security paradigms can be classified by either the scope of security measures taken (perimeter, layered) or how proactive the system is.
