robin keir’s giant port list

this time a short one, as i just stumbled upon the url again: i find robin’s extensive list of commonly used ports really useful. it lists both tcp and udp ports in the whole range up to 65535. although iana’s list holds the official reservations of public ports, i believe that robin’s list is more up-to-date (i.e. backdoors don’t register ports – they plain use them).
