    I created the scope the same way with the 192.168 and it dished out IP addresses just fine.
    Will this solve the DNS issues?

    Try not to concern yourself with classes, since supernetting became the norm that terminology is no longer relevant. For example you can supernet your class C range (192.168.x.x) by using a class B type mask (255.255.252.0) - so what is it; class B or class C? See how classes become blurred into each other, hence why people tend not to use that terminology anymore (yes I know books do but thats theory based on 80/90s tech)

    There is no reason why the above won't work so long as everything has the same subnet mask: 192.168.0.0-192.168.2.255 with mask 255.255.252.0 is one network/subnet/supernet.

    You don't NEED a L3 switch or vlans to have different subnets on the same physical network. In production, as FNGM said, the reason is to limit broadcasts and to segregate the network for security. For testing you can just pretend its vlaned.
