Consider the network shown below which contains four IPv$6$ subnets, connected by a mix of IPv$6-$only routers $($shaded blue$),$ IPv$4-$only routers $($shaded red$)$ and dual$-$capable IPv$6/$IPv$4$ routers $($shaded blue with red interfaces to IPv$4$ routers$).$

Suppose that a host of subnet B wants to send an IPv$6$ datagram to a host on subnet D$.$ Assume that the forwarding between these two hosts goes along the path: B $-->$ c $-->$ d $-->$ E $-->$ D

Answer the following questions:

a$)$ What is the source address of this B to c datagram?

b$)$ What is the destination address of this B to c datagram?

c$)$ What is the source address of this encapsulated datagram inside this B to c datagram?

d$)$ What is the destination address of this encapsulated datagram inside this B to c datagram?

e$)$ What is the source address of this c to d datagram?

f$)$ What is the destination address of this c to d datagram?

g$)$ What is the source address of this encapsulated datagram inside this c to d datagram?

h$)$ What is the destination address of this encapsulated datagram inside this c to d datagram?

i$)$ What is the source address of this E to D datagram?

j$)$ What is the destination address of this E to D datagram?

k$)$ Is this E to D datagram encapsulating another datagram? Yes or No$\mathrm{.}0$
