undefined method `link_local?' for #<IPAddress::IPv4:0x007fbd8353e880>

[RedaBenh]

To reproduce

> ip_adr = IPAddress('192.168.0.1')
> ip_adr.link_local?

or

> ip_adr = IPAddress::IPv4.new('192.168.0.1')
> ip_adr.link_local?

I get this error:

NoMethodError: undefined method `link_local?' for #<IPAddress::IPv4:0x007f9c7c790a70>

Support was added in f35aab8. No release of the gem happened since that time, so you'll have to tweak your Gemfile to fetch the gem from GitHub at that commit or a more recent one, e.g.

gem 'ipaddress', git: 'https://github.com/ipaddress-gem/ipaddress.git', commit: 'f35aab8e9109864945f606bef3e135be3763b9c4'
