Which statement is true about the address 173.194.75.105 in the traceroute example?

• A. It is an IP address
• B. It is a MAC address
• C. It is a hostname
• D. It is a DNS record

Answer: (A)

In traceroute, the addresses shown for each hop are IPv4 addresses used to route packets through the network. The string 173.194.75.105 is in the familiar IPv4 dotted-quad format, identifying a specific device on the Internet. It is not a MAC address, which is a 48-bit hex value such as 00:1a:2b:3c:4d:5e, nor a hostname like example.com, which would be textual. It’s also not a DNS record itself—the DNS system stores mappings like names to addresses, while the value you see in traceroute is the actual numeric IP assigned to a hop. So, this is an IP address, which is why the statement is true.
