Subnetting CIS$192-$ Lab #$3$

Subnetting

Question $1$: Do the following conversions $($show how you derive the outcome$)$:

$(10010011{)}_2=(?{)}_{10}$

$(11111111{)}_2=(?{)}_{10}$

$(192{)}_{10}=(?{)}_2$

$(5AF3{)}_{16}=(?{)}_2$

$(1011011011110001{)}_2=(?{)}_{16}$

$(847{)}_{10}=(?{)}_{16}$

$(BAD{)}_{16}=(?{)}_{10}$

$(9A6{)}_{16}=(?{)}_{10}$

$(65{)}_{10}=(?{)}_2$

$(783{)}_{10}=(?{)}_{16}$

Question $2$: A host computer is assigned IP address $192\mathrm{.}168\mathrm{.}12\mathrm{.}8$ and subnet mask $255\mathrm{.}255\mathrm{.}255\mathrm{.}192.$ The

host sends a packet to another host with IP address $192\mathrm{.}168\mathrm{.}12\mathrm{.}65.$ Is the destination IP address in the

same subnet as $192\mathrm{.}168\mathrm{.}12\mathrm{.}8?$ Show why or why not.

Question $3$: The subnet mask $255\mathrm{.}255\mathrm{.}255\mathrm{.}224$ is applied to a packet with destination IP address

$192\mathrm{.}168\mathrm{.}12\mathrm{.}135.$ Which subnet is the packet sent to$?$

Question $4$: The subnet mask $255\mathrm{.}255\mathrm{.}255\mathrm{.}0$ is applied to packets with the following IP addresses. Which

subnet is each packet sent to$?$

a$.10\mathrm{.}20\mathrm{.}35\mathrm{.}12$

b$.10\mathrm{.}20\mathrm{.}35\mathrm{.}3$

c$.10\mathrm{.}50\mathrm{.}35\mathrm{.}6$

d$.192\mathrm{.}168\mathrm{.}12\mathrm{.}8$

Question $5$: Given the IP address $193\mathrm{.}10\mathrm{.}10\mathrm{.}0$ and assuming that four subnets are to be created, answer

the following questions.

a$.$ What are the network address and the broadcast address for each subnet?

b$.$ What is the subnet mask?

c$.$ What is the number of usable hosts per subnet?

Question $6$: Given network IP address $211\mathrm{.}123\mathrm{.}83\mathrm{.}0$ and assuming eight subnets are to be created,

answer the following questions. The eight subnets include the network address and broadcast address.

a$.$ What are the network address and the broadcast address for each subnet?

b$.$ What is the subnet mask?

c$.$ What is the number of usable hosts per subnet?
