Invalid IPv6 handling

[traxanos]

Hi guys,

i have found a bug.

It is allowed to use dot notation in ipv6. The following address is not a mapped ipv6 address.

IPAddress.parse('abcd:9234::1.2.3.4/96').to_string

I got a wrong output
=> ::ffff:9.2.3.4/96

But the correct output must be:
=> abcd:9234::102:304/96

Same problem here:

IPAddress.parse('::1.2.3.4/120').to_string
=> "::ffff:1.2.3.4/120"

Correct output is
=> ::102:304/120

Only
IPAddress.parse('::ffff:1.2.3.4/120') is a mapped ipv6 value!
Only here it is allowed to handle it as an Mapped IPv6 Object with the following output:
=> "::ffff:1.2.3.4/120"

I have create a workaround for me

if value =~ /:/
converted = value.gsub(/([0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3})/) { |a| IPAddr.new("::#{a}").to_string.slice(-9, 9) }
else
converted = value
end
IPAddress.parse(converted)
