Subject: indent strings(make them lined up)

Hi,

I am newbie in Ruby. I have a question about indenting string.

there is strings like below:

www.google.com => 123.123.123.12
www.ibm.com => 123.112.123.12
www.iowahawkeyes => 123.123.112.12

i want to make above like next

www.google.com     => 123.123.123.12
www.ibm.com        => 123.112.123.12
www.iowahawkeyes   => 123.123.112.12


original code was

puts (dns + " => " + ip)

I tried next code

puts (dns + "  "*(20 - dns.length) + " = > " + ip)

but it did not work well. please teach me how to do it.
