What is a logical network? How do you improve one?
Learn what logical and physical networks are and how to improve them, in this expert response with networking fundamentals expert, Chris Partsenidis.
Q: What is a logical network is and why are they important? Also, what are the best solutions or measurements are to improve logical networks.?
A: The term "logical network" is usually combined with the known term "physical network." When designing a network, the "logical" part refers to the IP addressing scheme used within the network. For example, 192.168.0.0/24 could be the logical network used for our design. Breaking up our example, our logical network consists of a few important points, which we should be aware of:
- Network ID (192.168.0.0)
- Subnet mask (/24 = 255.255.255.0)
- Usable IP addresses (254 IP addresses)
- Broadcast address (192.168.0.255)
This information exists in every logical network and is vital information as it helps us determine how the design will be usable according to our needs.
Selecting the appropriate IP numbering scheme and subnet mask will determine how many usable IP addresses will be available for you. If you have many networks within your company, you should then be careful not to have overlapping or similar networks. Each network must be unique, otherwise routing problems can occur.
