IPAddr#to_json remove prefix address with CIDR

[taketo1113]

IPAddr#to_json removed the prefix address with IPAddr/CIDR value.
It unable to deserialize IPAddr/CIDR value.

Expected behavior

require 'date'
require 'json'

IPAddr.new('172.16.0.0/24').to_json #=> "\"172.16.0.0/24\""

Actual behavior

require 'ipaddr'
require 'json'

IPAddr.new('172.16.0.0/24').to_json #=> "\"172.16.0.0\""

The JSON gem has no specific support for IpAddr. I suspect this is a change in IpAddr#to_s which is what JSON call when it doesn't know about a particular type.

Thanks to reply.

The JSON gem has no specific support for IpAddr.

I will create PR to add IPAddr#to_json method in ipaddr gem.
Becase I think the changing behavior of IPAddr#to_s has breaking compatibility.

see. rails/rails#52365
