A network administrator has signed up for service with a new ISP. The administrator was given the IP address of 172.17.10.254/30 to use on the external interface of the Internet-facing router.
However, the network administrator cannot reach the Internet using that address.
Which of the following is the MOST likely explanation?
A . The address provided by the ISP has a mask that is too small to be used and needs a larger mask.
B . The address provided by the ISP is a private IP address space and is not routable on the Internet.
C . The address provided by the ISP is the wrong one; they should be using 172.17.10.252/30.
D . The address provided by the ISP is part of the reserved loopback address space and cannot be used.
Answer: B
