Renew ip in Sun Solaris (Virtual Server)

I attended MYSQL Cluster  training from Oracle and using Sun Solaris in Hyper-v for Lab purpose.

When I brought my computer to training center, I needed renew my IP so I can't connect to Sun Solaris in Hyper-v with Tightvnc viewer (I use this to solve Mouse trap problem in Sun Solaris at Hyper-V)

In window environment, I always run this
IPCONFIG /renew

In *inux version, I don't know how and always restart Virtual server to get the latest IP.

Do some search and come this
list ip of the network in my virtual pc
/sbin/ifconfig -a

net0 is my ip.

I run the below
 ifconfig net0 dhcp status
ifconfig net0 dhcp release
ifconfig net0 dhcp status

and then

ifconfig net0 dhcp primary
ifconfig net0 dhcp status
The IP is refresh.

I get the information from here and it work in my Virtual Server.
