I'm sure this has been asked before, but how do I get my IP address so that I can then display in as an NSString?

Any help is appreciated.
Thanks.

Well you could use NSHost
[[NSHost curentHost] addresses]

but many users have reported that it only returns 127.0.0.1 (not for me tho.)

Anyway, for me it returns a NSArray of 2 NSStrings "127.0.0.1" which is localhost, and "192.168.123.185" which is my "lan address" ( nobody outside of your networks could contact you with that address )

I guess what you're interested in would be the "external" IP address (the one people outside of your lan see) something like 65.74.21.11

Well the easiest way I know would be to parse the html at

http://checkip.dyndns.org (which isnt really hard)

it's pretty easy to fetch, ( use NSString's initwithContentsOfURL, CURLHandle (curlhandle.sf.net) or even a 10 lines/max bsd socket call )

I hope that helps!

Thanks. I'll try that.

(Luckily I built in a parse HTML feature in my app, Poster.)

Well it's basically a three lines NSScanner trick, so...
