June 05, 2007 Get Local Ip Address? | ||||
---|---|---|---|---|
| ||||
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! |

Posted in reply to okibi | 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/. -[Unknown] okibi wrote: > Hey, > > I was wondering if there is a simply way to get the public IP address of the machine.

Posted in reply to Unknown W. Brackets | 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.

Posted in reply to okibi | 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.

Posted in reply to Unknown W. Brackets | 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++.
