Hi all,

Here's a (hopefully) simple question: How do I get a string containing my IP address (e.g., "129.200.123.456")? TIA!
 
Hi,
U can retreive IP address from server variables.
Request.Servervariable("REMOTE_ADDR")

Whoops... sorry, I guess no question is ever as simple as it seems. My application is a Windows Forms application, not a web app.
My question should more properly have been:

How can my Windows Forms app get a string containing my IP address (e.g., "129.200.123.456")

TIA!
 
Hi,

Try this

using System.Net;

System.Net.IPAddress addr;
addr = new System.Net.IPAddress(Dns.GetHostByName
(Dns.GetHostName()).AddressList[0].Address);

addr.ToString() is an IP address.

Hope this will help U

Regards

Keep in mind that this only gets you one of the machine's IP addresses.
 
Thanks for the code sample. It gives the correct result, but I get a compilation warning to the effect that the Address() property
is obsolete because it is address family dependent. Is there a way to do this without using the Address property?

It turns out that this simpler expression returns the IP dot address without referencing the obsolete Address property:

Dns.GetHostByName(Dns.GetHostName).AddressList(0).ToString



Thanks again for the help!

Bob, are you aware that "address family dependant" means that it could be an
IPv6 address? In that case, the result of .ToString will be a much longer
string with hexadecimal digits and colons instead of decimal digits and
dots.
 
John,

I guess that makes perfect sense. I'm looking to get the string form of the numeric IP address so that I can give it to other
computers in my network so that they can talk to me. If we're using IPv6 then I would expect to give them a string in IPv6 format.

Thanks everyone for the help!
