Retrieving an IPV6 throw an exception

[jjsaunier]

When you retrieve an ipv6 via getDetails for example, it throws Symfony\Component\Cache\Exception\InvalidArgumentException Cache key "xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx_v1" contains reserved characters "{}()/\@:".

We hit the same problem. I've made a PR to fix it, but we still need to wait for the code owners to merge it.
In the meantime, just use 3.0.0 which doesn't use Symfony cache.
