I am looking for a package that is similar to Net_IPv4 and Net_IPv6 but written for Java. It needs to be able to do the following:
It would be awesome if it could also:
I could probably write a package to do all this, but if someone has already gone through the trouble and most likely has done a better job, I'm all about using that. Anyone know of such a package or packages that could do all this? We are expanding into IPv6, so it needs to work for both IPv4 and IPv6 if possible.
I appreciate any help.

In Java, this can be done using Pattern. matcher(). Return true if the string matches with the given regex, else return false.
IPv4 to IPv6 mapping To convert Internet Protocol 4 (IPv4) to Internet Protocol 6 (IPv6), perform the following steps. Open the tool: IPv4 to IPv6 converter. Enter any valid IPv4 address, and click on the "Convert to IPv6" button. The tool will process your request and provide you the converted IPv6 address.
We can use InetAddressValidator class that provides the following validation methods to validate an IPv4 or IPv6 address. isValid(inetAddress) : Returns true if the specified string is a valid IPv4 or IPv6 address. isValidInet4Address(inet4Address) : Returns true if the specified string is a valid IPv4 address.
IPv4 addresses are separated by periods, while IPv6 addresses are separated by colons. Both IP addresses are used to identify machines connected to a network.
Maybe CIDRUtils can help you. It enables you to convert CIDR notation to an IP range.
