How to understand network addresses and sub-net addresses in the learning material of AZ-104
Hi Everyone, I am currently studying for the AZ-104 Certification using Microsoft Learn. My greatest challenge is learning the Networking component of the learning material. I am confused by the way that sub-nets are presented in the learning material. With my understanding of networking a network should not have a different mask to a sub-net. Here is an example screen capture from the learning material - Given the above example IPv4 address space the mask is - /20 which in binary is - 11111111.11111111.11110000.00000000 which in Decimal is - 255.255.240.0 This network mask should allow for the following sub-nets - 10.40.0.0 10.40.16.0 10.40.32.0 10.40.48.0 10.40.64.0 10.40.80.0 10.40.96.0 10.40.112.0 10.40.128.0 10.40.144.0 10.40.160.0 10.40.176.0 10.40.192.0 10.40.208.0 10.40.224.0 10.40.240.0 Can anybody explain how the sub-net (in the screen capture) 10.40.0.0/24 factors in? Kind Regards, Davo
