I have a huge list of proxies with ports in IP:PORT format. I need to extract all the proxies that use the port ranges 80-8081 including common ports like 3128 and 8080 and ignore all the rest. The regular expression I'm using is "(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}:\d{1,4})", how can I do this using a single captchering regexp statment?
