Frequently Asked Questions
What is VLSM?
Variable Length Subnet Masking lets you use different subnet sizes within one network, matching each subnet to the number of hosts it needs and wasting fewer addresses.
What is CIDR notation?
CIDR writes an address with a prefix length, such as 192.168.1.0/24, showing how many bits identify the network. It replaced rigid classful addressing.
Why summarise routes?
Route summarisation combines many networks into one advertisement, shrinking routing tables and hiding instability. This free intermediate Codelivly room shows how to plan addresses so summarisation works.
