v2_6_3 - Show latest stable - Superclass: Object

IPAddr provides a set of methods to manipulate an IP address. Both IPv4 and IPv6 are supported.

Example

require 'ipaddr'

ipaddr1 = IPAddr.new "3ffe:505:2::1"

p ipaddr1                   #=> #<IPAddr: IPv6:3ffe:0505:0002:0000:0000:0000:0000:0001/ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff>

p ipaddr1.to_s              #=> "3ffe:505:2::1"

ipaddr2 = ipaddr1.mask(48)  #=> #<IPAddr: IPv6:3ffe:0505:0002:0000:0000:0000:0000:0000/ffff:ffff:ffff:0000:0000:0000:0000:0000>

p ipaddr2.to_s              #=> "3ffe:505:2::"

ipaddr3 = IPAddr.new "192.168.2.0/24"

p ipaddr3                   #=> #<IPAddr: IPv4:192.168.2.0/255.255.255.0>
