Best way to add subnets into AD sites and services

When adding subnets into sites and services can they be added as 10.0.0.0/8, or do they need to be entered more as 10.222.208.0/21.

I;m just trying to find a way to cover all subnets at once.  Any thoughts?

It really depends on your network and how you are segmenting.  if you use the /8 then all the subnets will be associated with that site in this scenario.  This is actually known as a "catch all subnet"   More on that in the link below

For eg you have 3 sites in AD or physical network i,e australia (192.168.10.0/27) US (192.168.1.0/27) UK (192.168.2.0/27) here you will need to create three different subnets and link to there respective sites

If you have one site and that has all three subnets then also you need to create all three subnets and link it to same site

Do not use shorcuts sometime it may complicate things
