[src/oneliner] Getting the IP from an external rescource in ruby

[mrpink]

Hi,
just for fun I wanna share this oneliner which prints you the external
IP on the screen

require 'net/http'

Net::HTTP.get_response(URI.parse('http://www.wieistmeineip.de')).body.scan(/^Ihre
IP-Adresse ist.+/) { |ipadresse| puts
ipadresse.sub(/^.+">/,'').sub(/<.+$/,'') }

greets

Interesting. I expected my code to be equivalent, but it gives a
different answer:

$ ruby -r resolv -e 'p Resolv.getaddress("http://www.wieistmeineip.de")'
"212.19.62.76"

If I may translate: the German parts into English:


Net::HTTP.get_response(URI.parse('http://www.whatismyip.com')).body.scan(/^Your
WAN IP is.+/) { |ipadresse| puts ipadresse.sub(/^.+">/,'').sub(/<.+$/,'') }


The one liner resolves your external IP with the help of an external
service.

A hint for mrpink: German is not widely spoken beyond Germany, Austria
and Swiss, so it's a good idea to translate your output.

lol my output prints a plain IP-adress on the screen and nothing else
and you're code is of course not working because you conducted my
regular expression with an output string muahhh
