Add Multiple IP Addresses
-
I want to add ip address to my lan card by using Management class' method like GetMethodParameters("EnableStatic") ; but i am unable to assign multiple ips to my lan card is there any way to add ip address programmatic, like we use advanced tab and then ip settings tab to add another ip address, or is there any way to call net set command using C# Thanks in Advance Regards

WHY do you want to add IP addresses? What is your purpose? Are these IP addresses yours?

Yes those ip addresses are of our network, basically i want to ping that ip address if no reply from ping is returned then i want to add that ip as secondary ip of my lan card, just like dhcp but i dont want to use dhcp caz i have specific ips

Still does not make sense. Adding an IP address to your interface brings you nothing, if the rest of the world doesn't know about it. The only situation where this could be valid is if you have a physical subnet which carries 2 or more logical subnets, where only one of them is DHCP enabled. There may also be uses if you're defining a fault tolerant cluster, where you reserve fallback addresses, but in that case you should reserve them first. In all other situations, you are going to mess up routing tables, impact your own connectivity, and generally be a nuisance to everyone on the network. Doing it programmatically only guarantees that you're ALWAYS a nuisance.

There's a thing called DHCP. It's part of the operating system. Use it.

He's trying to do what DHCP does.

i have done this by another method, i pinged my desired ip and then if that ip pinged fail, i created a batch file to process and assigned that ip to my nic. thanks for your responses, if any one among you guys get the solution to do without executing batch file means through coding. Regards

Yeah, but why would you even want to do this? Just pinging an IP to see if it's alive then assigning it to you LAN card gets you nothing. If you're adding IP addresses to the card that are not even part of the subnet that your machine is on just gets you wasting your time since you can't route traffic to that IP if it's not on the correct subnet.

But no longer in 2009...Actually the purpose to this all scenario is, we work on real time systems in which we are going to arrange high availability of system, like two main servers, two branch servers and etc, there would be only one main server and one branch server running in one time if one of the each server (either branch or main) get fails to respond to its counter part, then another (branch or main server) gets which are already powered on gets connected to its counter part. hope you could understand the scenario Regards

So basically, you're trying to kludge together a "poor mans cluster". This is not going to implement a "high availability" system. You've got a couple of problems. First, neither server is going to have an exact copy, if at all, of the data the other one has. There has to be some kind of syncing going on. There is going to be, in most cases, a substantial lag between one server storing data and the other one picking it up. Depending on the amount of data you have to sync, this can take from minutes to hours to complete 1 sync cycle. Next, what's you're polling interval going to be for pings? What's you're timeout going to be? How many pings in a row must the server not respond to before it's considered failed? What if both servers are actually running and it's just the ping that didn't come back? Now you've got two servers with the same IP's running and you'll end up with even bigger problems. Another problem is how are you going to recover the failed server once it's back up? When it comes back up, it should have it's original IP address to match it's DNS record. Now you've got 2 servers going on the same IP address and the one that hold both IP's has no way of automatically determining that the failed server is back up and running because ping's going to that address will get routed back to the "good" server without ever going down the network cable. At a certain auto manufacturer I used to work for, we did something similar. It was impossible to get the lag time down between the two servers to under 4 hours because they had to sync up hundreds of GB of data constantly. Once server always had a copy of the data that was at least 4 hours old, and probably longer. IMHO, you should be looking for an actual cluster or single IP solution depending on your requirements. Doing something like this is not scalable at all. If you added more servers, this solution cannot be expanded without rewriting the code to "steal" IP addresses.
