I have an issue where I have a remote IP Address, and I need to discover the
local network interface IP Address which is viewable to the remote IP Address
(for UPnP document purposes). For example, if I have the remote IP Address
10.0.0.4, and I know all of the local IP Addresses:
127.0.0.1
10.0.0.5
10.1.0.20
192.168.0.5
157.54.185.126
How can I determine which of these IP addresses, without connecting to the
remote machine, that if broadcast over that network interface, the remote
device could see the broadcast and also connect to the local machine at that
IP address. I was looking at some properties in the NetworkInterfac e class
and stuff, but nothing was obvious to me. I hope I am explaining the problem
well enough.
Thanks 1 2404

Well, given your remote IP address, you should be able to apply your local
subnet mask to the remote address and each of your local addresses, and if
they result is equal then those addresses are on the same subnet.
But, you really shouldn't need to do this. Just broadcast to
IPAddress.Any, and assuming the remote machine is reachable, it will
receive the broadcast and can use the origin IP address to determine how
to connect back. There should be no reason for your local process to know
or care what the configured IP address is.

Hi,
Probably an easy answer to this, but I have not been able to figure it out.
How can I find the IP-address of the machine that my Java-program is running
on ? Could not find any methods in the InetAddress class that does this. The
closest I got was the getLocalHost() which will return the IP-address
representing the loopback address (usually 127.0.01, isn't it ?).
Any ideas ?

I come from C but don't really understand why in C++ you can return a temporary object

For example:

Hi everyone
I'm trying to lock my SQL Server Desktop Edition down which is running
on a relatively fresh install of Windows 2003 Server Standard Edition
which is a dedicated server from Fasthosts.
I'd like to create a local security policy that denies access to all
remote addresses other than my fixed IP address at home and work.
However, all attempts to create a policy just result in nothing

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
