No, user space Perl programs cannot do that. Your only option is to accept or not accept a connection - and you cannot get the information of an incoming connection (like its IP address) without first accepting it.

What you want to do is normally done at kernel level (although in some implementations, the kernel can consult a user space program to make the decision).
