1. If OSU has an IP address whose first byte is 128, what class does this IP address belong to? (Use the old class system adopted for IPv4).

2. To which of the four bytes of the IP address can OSU assign values, assuming the first byte has the value 128? (Use the old class system adopted for IPv4).

3(a) Assume that ICANN has assigned OSU a group of IP addresses, and that the first two bytes (of each assigned IP address) are 130.192. In this case, how many IP addresses are available for OSU? (Use the old class system adopted for IPv4).

3(b) How many IP addresses are available to OSU, if ICANN assigned OSU a class A IP address? (Use the old class system adopted for IPv4).

3(c) How many IP addresses are available to OSU, if ICANN assigned OSU a class C IP address? (Use the old class system adopted for IPv4).
