Address Assignment Information

You can divide a VNet into multiple subnets for organization and security. Each NIC in a VM is connected to one subnet in one VNet. NICs connected to subnets (same or different) within a VNet can communicate with each other without any extra configuration. You can change the subnet a VM is connected to after it's created, but you cannot change the VNet. Each NIC attached to a VM is assigned a MAC address that doesn’t change until the VM is deleted.

Reserved addresses in each subnet:

The addresses x.x.x.0 to x.x.x.3 in every subnet and the last addresses in every subnet are reserved.

• x.x.x.0: network address
  
• x.x.x.1: default gateway
  
• x.x.x.2, x.x.x.3: DNS services
  
• x.x.x.255: broadcast address
  

The automatically configured default router of a subnet does not respond to a ping command.

The traceroute command does not work.

Multicast, broadcast, and GRE are not supported.
