Safety: A dial up connection is much safer than any other technology because of the rotation of the IP addresses, assigned to a user. IP address is a set of numbers assigned to you, that you use to connect to the Internet. So, wherever you go you leave a trail behind. Using a dial up connection, every time a person logs in, he does so using a new IP address. This makes hacking an account impossible and saves the user a lot of headache. IP address theft has some serious consequences, like someone can login using your IP address and do 'wrong things' that may actually point back at you.
