if i use :  
Net::HTTP.start(‘[http://88.183.xyz.uvw](http://88.183.xyz.uvw)’)  
with numerical (i don’t have a domain name)  
i get an error :

essais/download\_files.rb:16: no . floating literal anymore; put 0  
before dot  
[http://88.183.xyz.uvw](http://88.183.xyz.uvw)  
^

does it mean Net:HTTP wants to translate the numbers given ?  
being somehow a bug for an address right ?

however it seems Net::HTTP can’t download a file from an unregistered  
domain :  
/opt/local/lib/ruby1.9/1.9.1/net/http.rb:581:in `initialize’:  
getaddrinfo: nodename nor servname provided, or not known (SocketError)

Net::HTTP.start doesn’t take a url, it takes a hostname and optional  
port.
