I'm working on an issue in Elytron, which requires validation of IPv6

Do we use some standard library for such purposes, or is there such

wildfly-network package, which does some of that, but that

in Elytron.
What is the use case?
Detection of and matching of IPv6 addresses including canonicalisation
for different representations of the same address.
Note: This is not DNS lookup or reverse DNS lookup.
Are there some rules when considering new dependencies? For instance
would Apache Commons Validator/Net represent conceivable dependencies
for Elytron?
new runtime dependency? I would avoid them if possible.
Especially when it comes to Apache Commons * ...
+1 This code may be used by all remote clients and all deployments.
