Note: Consider figl and answer all questions:

$1$: ISP BSNL have address block $130\mathrm{.}10\mathrm{.}60\mathrm{.}0/22.$ MNNIT request for $500$ addresses and NIT warangal $($NITW$)$ request for $200$ addresses, how BSNL will fullfill requirement of MNNIT and NITW. Allocate IP address to each interface of routers and $P{C}^{\text{'}}$shown in figl.

$2$: Show routing table of router $R_{bsnl},R_{\text{g}\text{m}\text{n}\text{n}\text{i}\text{t}\text{,}}{R}_{\text{g}\text{n}\text{i}\text{t}\text{w}\text{,}}$ PC$1,$ PC$10.$ MNNIT and NITW network administrator do not know network addresses of each other.

$3.$ Trace movement of IP packet p$1$ from NITW pc$10$ to MNNIT pc$3.$ Trace movement of IP packet p$2$ from PC$1$ to iitk web server. Assume IP of iitk web server is $202\mathrm{.}141\mathrm{.}55\mathrm{.}6$

$4$: Show switch table of S$11$ and how is it created? Switches are connected

through cat$6$ UTP cables with RJ$45$ connectors. Which connection line will use

CSMA$/$CD and where collision may occur?

$5$: PC$4$ sends a DNS query for NITW web server nitwwsr $($www$.$nitw.ac$.$in$).$ How this DNS query get resolved?

$6$: consider a TCP connection between PCI and NITW web server nitwwsr. Show transfer of $9$ segments from PCl to nitwwsr. Segment $4$ and $7$ get lost during transmission. Window size at PC$1$ is $10$ segments. TCP is using single timer for time out and it is not using duplicate ACKs for fast retransmit.
