2) Classfull addressing has been long deprecated however network engineers will often refer to a network as being a "Class A", "Class B", or "Class C" network. For the following networks give the netmask in dotted decimal notation and the "Class" of each of the following networks.

Please give your reasons for your choice of Class.

i. 192.168.1.0/24

ii. 172.31.9.0/27

iii. 8.7.0.0/16

iv. 126.0.1.192/29

Please note: some of you might still find this notion of class a little confusing. I've asked the above question with the intent that you tell me what you think Class means.
