All of the above attributes also allow you to specify an error message that is displayed in the event of an error.If an error message is not specified, a default error message is displayed.An IP address is of the format [0-255].[0-255].[0-255].[0-255], so a regular expression with this format should serve the purpose, or the IP address string can be split using the String.split(...) and a check can be added.Every computer connected to the Internet is identified by a unique four-part string, known as its Internet Protocol (IP) address.This c program prints ip (internet protocol) address of your computer, system function is used to execute the command ipconfig which prints ip address, subnet mask and default gateway.The code given below works for Windows xp and Windows 7.

The format of an IP address is a 32-bit numeric address written as four decimal numbers (called octets) separated by periods; each number can be written as 0 to 255 (e.g., 0.0.0.0 to 255.255.255.255).If you have a requirement to change the virtual IP address of your SQL Server failover cluster, read this tip for step by step instructions. To take offline, right click on the IP Address in failover cluster manager as shown below and click on "Take Offline".The virtual IP address in a failover cluster is used to make a connection to SQL Server databases from your client applications instead of using the physical server name or physical IP address of the server. When a failover occurs, the ownership of the virtual IP address moves to the other node, so you don't have to change the connection string for your application to work. After the resources are offline, right click again and click on "Bring Online".Since this is only a two-node cluster, it can only failover to the second node.Once failover is successful, again connect to the SQL Server Instance by using the new virtual IP and run the T-SQL command below.
