EDIT: Forgot to say its piss easy to use as well.
Heres another external ip finder based on Mikezs one, however maybe a bit more advanced. I needed this plugin to tell my family my ip because they all download files from my ftp, but Mikezs' never gave me the correct ip address.
It can use either a direct connection to a ip server (developed by myself - so only my pc is running atm) or a connection by http to a php page where the ip will be parsed. The direct connection is usually quicker and much much much more accurate.
The but - i have the server executable (windows) however, have no where to run it except on my pc, so it will be on for a short time tonight so keep the default ip and you can use my pc for tonight, but if anybody has a spare pc on the internet around and anyone actually uses this plugin, i would be greatful if they would run a tiny server in the background.
Also, just to let you know, the direct connection sends only these strings, and these only from your computer:
"iprequest"
"hostrequest"
"quit"
Feel free to check this with a packet sniffer.
Enjoy. Please use the Plus! menu to use this plugin, saves me explaining the commands because im nakered.
Sorry for not asking you before posting Mikezs, but i couldnt find your email address anywhere
. Hope you dont mind
