7. A new window will pop up. Enter our DNS addresses (78.47.115.195 and 78.47.115.198) in the appropriate boxes, by first selecting the radio button called Use the following DNS server addresses. Look at the Internet Protocol Version 4 (TCP/IPv4) Properties  window below, since this is how it should look like when you are done. Ignore the different IP numbers in the window below (they are old IPs); the new IPs are mentioned above.
