353933 Check list of IP:Port

I want a script that myself or staff can input a list of IP's and ports information via a text box. Example format [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] Once this has been submited the script needs to strip the port part off and then check each IP in the list to see if it's been used on the sites database tables... I have 3 such tables that would need to be checked but only need the code script for one as once given the script i can change it to look at the other tables as needed... Easy enough i bet for some of you
