I’ve submitted a tool called IP Lookup to the app store for initial release. I honestly feel this is the most complete TCP and UDP port reference tool available anywhere. It currently has over 12,000 entries, and the list is still growing.
As you can see it includes a search function. Not only can you search on port numbers, but portions of the description as well. For example searching on the keyword “malware” produces a list of ports used by worms, backdoors, etc.
One of the key features of the tool is that the list is live sorted while you type. So as you start typing in your search criteria you’ll immediately see the results in the list.
Hope you enjoy the tool!
