Current registry reference use a subset of dns and IPv4 addresses to represent a registry domain. Since registries are mostly compatible with rfc3986, that defines the URI generic syntax, this adds support for IPv6 enclosed in squared brackets based on the mentioned rfc. The regexp is only expanded to match on IPv6 addreses enclosed between square brackets, considering only regular IPv6 addresses represented as compressed or uncompressed, excluding special IPv6 address representations.
