I am sure many of you have seen me post on here about port forwarding on a mac. So many of you have told me that I need to make a static IP address, and many of you have also given me links to "Port Forward.com". I was trying to find out my isp (internet service provider) and found that it was Comcast. My mom works for Comcast, so I asked her about DNS ip addresses, and when she looked at the screen for making a static IP address, she said that static IP addresses are dangerous because they open your computer to hackers, and are actually made for Business groups so that when they change locations, they will be located at the same place. So what is all this about? Do I really need to make a static IP address? Are they really dangerous? I know my router and everything, so that part is solved. But for each question I solve, two more pop up. Please help me, even better if the person who helps owns a mac him/herself.
