Here we only consider two fields in the BGP announcements: the IP prefix and the AS path. For example, an update for one of the Google's prefix has the following fields: 216.239.34.0/24 15169|23947|3491|4436 From left to right, the numbers in the AS path represents the origin AS, the first-hop AS, the second-hop AS, etc. Explain your answer for: a) Google (AS number 15169) provides free DNS service on 8.8.8.8, which is part of the prefix 8.8.8.0/24. How can an attacker hijack the traffic toward this IP prefix? Explain the procedure for both origin hijacking and path spoofing methods. (5 points)
