RFC Address Ranges
For those preparing for Cisco certification exams, knowing the correct RFC address ranges is a must. The most common RFCs are Class A (1.0.0.0 to 127.255.255.255), Class B (128.0.0.0 to 191.255.255.255), and Class C (192.0.0.0 to 223.255.255.255). Knowing these addresses will help you understand how networks are assigned and configured, giving you a better understanding of networking fundamentals. For practice, try answering the following questions:

  1. What is the maximum number of IP addresses that can be assigned to a single Class C network?
  2. Which class of addresses has a default subnet mask of 255.255.0.0?
  3. What is the highest possible IP address in a Class A network?
  4. What is the lowest possible IP address in a Class B network?
    Answering these questions should give you a better idea of how different IP address classes work, which can help you prepare for more advanced Cisco certification exams.

OSPF Router Types
For those studying for their Cisco certifications, OSPF router types are an important topic to understand. OSPF (Open Shortest Path First) is a routing protocol used to find the best path for data packets to take between two networks. It does this by assigning each node on the network a cost for each route, which is then used to calculate the optimal route. There are three main types of routers used in OSPF networks: the internal router, the backbone router, and the area border router.

An internal router is responsible for routing within a single area or between multiple areas within an OSPF network. They are connected to other internal routers and can pass data packets between them. Backbone routers are used to connect multiple areas together, providing an efficient way for data packets to move between different areas of the network. Finally, an area border router (ABR) is responsible for connecting an area to a backbone router and routing data packets between the two networks.
It’s important to understand the differences between these three router types when preparing for your Cisco exams. Being able to identify each type and know its purpose will give you an edge when answering questions on your exam.
