1.So the need to do that stems from my first DC to have a static IP address; default VM is a part of a subnet, which seems to have a router, when I drop static IP on the machine, I loose it (Get-AzureVM -ServiceName StaticDemo -Name VM2 | Set-AzureStaticVNetIP -IPAddress 192.168.4.7 | Update-AzureVM). How these boxes see each other in a custom subnet? Are there switches? Do these subnets can get routers? If not, how do I access them without inbuilt VPN?
2. I learned my networking via CISCO; if I pick 192.168.1.0/26 network, for example, I get 4 subnets, each having 63 addresses, 62 are usable, as 63 is a broadcast and 62 is usually a default gateway. When I do the same in Azure, I get 59 available addresses; please specify what are those, and what happened to 3 addresses missing. Also, provide guide info on your highly custom networking, unless you are sticking to the norm.
