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

essais/download_files.rb:16: no .<digit> floating literal anymore; put 0
before dot
http://88.183.xyz.uvw
              ^

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