Communications and Networking:

A router has the following CIDR entries in the routing table:

Address/Mask	Next Hop
135.46.56.0/22	Interface 0
135.46.60.0/22	Interface 1
192.53.40.0/23	Router 1
Default	Router 2

a.For each of the follwoing IP addresses, what does the router do if a packet with that address arrive?
1. 135.46.63.10
2. 135.46.57.14
3. 135.46.52.2
4. 192.53.40.7
5. 192.53.56.7

b. A Large number of consecutive IP address are available starting at 198.16.0.0. Suppose that four organizations, A, B, C, D request 4000, 2000, 4000, and 8000 addresses, respectively, in that order.
For each of these, give
a. the first IP address assigned,
b. the last IP address assigned
c. and the mask in the w.x.y.z/s notation.

c.PPP is closely based on HDLC, which uses bit stuffing to prevent accidental flag bytes with the payload from causing confusion.
Give one reason why PPP uses byte stuffing instead of bit stuffing?
