Subject: Standardlib "ipaddr.rb"

Happy New Year Everyone,

I seems for me that there is a bug (or a feature) in the standard lib 
"ipaddr.rb". ;-)

See irb output ->

irb(main):001:0> require 'ipaddr'
=> true
irb(main):002:0> ip1 = IPAddr.new("192.168.1.243/24")
=> #<IPAddr: IPv4:192.168.1.0/255.255.255.0>

IMHO should it be #<IPAddr: IPv4: 192.168.1.243/255.255.255.0>

And there should be methods to get the "net" and in case of ipv4 maybe 
"broadcast" address of the prefix.

But this is just a suggestion cause this would be intuitive for me as newbie.
