I am using Tiny Personal Firewall and it seems to protect my system very well. Now and again I get a message that a site with address (i.e.) 255.255.255.255 port 67 is trying to send you information. My question is how do I know what the numbers stand for: such as Microsoft, Anadtech, etc. It's hard to make a decision especially when I don't know what site wants to access my computer or send me information. Any help would be most appreciated.
