Can't retrieve ip address

[Guest]

I trying to get a persons ip address using  <cfoutput>#cgi.REMOTE_ADDR#</cfoutput>, but all i'm getting is 0:0:0:0:0:0:0:1.Anyone know why and a better why to get it?

Do you have a firewall or other traffic management device between you and the outside world which might be routing external traffic onto an internal network? 

Check to see if this returns anything useful:

GetHttpRequestData().headers["X-Forwarded-For"]

I only have a router for a firewall. I used a site www.whatismyip.com and it gets it no problem.

That's localhost in IPv6 is it not? Are you running CF locally?

[Guest]

Yes running cf on my computer to test all cf applications.

[Owainnorth]

In which case that's probably correct and it should work when you put it live. As I say, that's localhost in IPv6.

I needed to add the persons ip to this application to make sure they don't submit a vote twice (site i'm working on). So since this doesn't work locally i have to come up with another way.

[Owainnorth]

Well to be clear - it *does* work locally - it's giving you the IP address of the client; it just happens that's localhost. You shouldn't redesign your entire application just because it doesn't work in this one case.

You shouldn't redesign your entire application just because it doesn't work in this one case.

Or indeed because it does work in this case.

You have yet to respond to Owain's IPv6 remark. I hope you are now convinced that 0:0:0:0:0:0:0:1 is actually the localhost IP. That is, it is the same address as 127.0.0.1, but then in IPv6 notation. Your computer is the only localhost. You can therefore safely assume that CGI.REMOTE_ADDR will return the IP address of other client computers out of your domain.
