awitpt::netip Math::BigInt performance issue.
we currently run policyd along with a Zimbra server and we experienced some performance problems. So we made some profiling with Devel::NYTProf and found that awitpt::netip::is_within was using a huge part of the system resources. The introduction of BigInt to manage (it's just my guess) IPv6 addresses is the cause. So I forked your repository and tried to fix this issue using Net::Subnet, which it uses only native Perl function to achieve the same result.
The commit with my changes is this.
