Practice Exam Lab Question

Given the IP address 202.10.40.0.

Boss asks you to subnet as such.....

Make at least 10 subnets.

No more than 10 hosts per subnet.

I answered correctly with /29.

11111111.11111111.11111111.11111000

255.255.255.248

Number of subnets = 2 squared by number of robbed bits.

2x2x2x2x2

two squared 5 times = 32 = 32 subnets

block size = the value of the digit just to the left of the line.

11111111.11111111.11111111.11111000

bs = 8 - 2 = 6 valid hosts per subnet.

first network id is 202.10.40.0

last broadcast address is 202.10.40.255

so you have

202.10.40.0 first subnet network address (subnet #1)
202.10.40.8 2
202.10.40.16 3
202.10.40.24 4
202.10.40.32 5
202.10.40.40 6
202.10.40.48 7
202.10.40.56 8
202.10.40.64 9
202.10.40.72 10
202.10.40.80 11
202.10.40.88 12
202.10.40.96 13
202.10.40.104 14
202.10.40.112 15
202.10.40.120 16
202.10.40.128 17
202.10.40.136 18
202.10.40.144 19
202.10.40.152 20
202.10.40.160 21
202.10.40.168 22
202.10.40.176 23
202.10.40.184 24
202.10.40.192 25
202.10.40.200 26
202.10.40.208 27
202.10.40.216 28
202.10.40.224 29
202.10.40.232 30
202.10.40.240 31
202.10.40.248 - last subnet network id (subnet #32)
-------------------------
202.10.40.256 does not belong to you.....

ok so there you have your network and subnetworks.....202.10.40.0/29

is that how you say it?....there you have your network and subnetworks?....

i don't think so and i will discuss at work regarding questions....

1. Given the address 202.10.40.0/29

Would you now need to get 32 ethernet interface cards to install into your router? Leaving you with one router and "sho ip int br" needs to say 32 fastethernet interfaces?

And where would be the Gateway IP address? Which would be the Gateway IP address?

And my understanding is that an ISP will often assign a /30 address to the serial interface for the customer. How does this /30 address come in to play in the customer premise physical topology and network design?

I mean we have a /29 address, 202.10.40.0/29. Where and how does this /30 address come in to play for the customer?

Draw network diagram showing router, switches, and hosts along with corresponding IP addresses. Post picture of network diagram to this blog.
