Hey,

I was wondering if there is a simply way to get the public IP address of the
machine. I need it to work on Windows and Linux.

Is there a simply way that will work on both?

Thanks!

Are you wanting the public IP address, or just the machine's IP address?

Example: my computer is in a network, so it's IP starts with 172.16. 
But, my public IP address starts with 72 or something (for my entire 
network.)

To get the machine IP, it's going to be more system-specific, and I 
don't know off hand how.  To get the public IP, you have to check an 
external source - e.g. http://www.whatismyip.org/.

Assuming the computer is connected directly to the internet (via a cable modem
or such), then it's IP should be the public IP. I guess, however, I'm asking
how to get the machine's IP.

Thanks.

Most computers are not connected directly, since they usually have a 
firewall (which most of the time involves a nat) in between.

I've never had need to get a machine's IP (always let it be configurable 
or use ADDR_ANY) so I'm afraid I don't know how.  I'm sure there's a 
way, but I suspect it varies by platform.

I know there's a way, and I can do it in C++, but I was just wondering if there
is an easy multi-platform solution in D.

Thanks guys!

There isn't. If you have an open socket you can get the local IP,
however all network connected systems have at least 2 IPs:
127.0.0.1(IPv4) / ::1(IPv6) and a public one like 89.50.67.60.

Many have more IPs (e.g. the system I'm posting from has 5 different
ones), thus I'd like to know how you get the right local IP with C++.
