But I added only tow new tests? And you show three failing, thus you still had some work to do even before I added the two additional tests [Big Grin]

Jens, I think you missed a subnet mask that makes TEST #8 true.

255.255.254.0 (/23) is also valid from what my code says. If you agree, then I have working code again.

code:
IP Address         = 10.10.10.2
Network ID = 10.10.10.0
Subnet Mask =
Correct Answer =
Alternative Answer = /24,/25,/26,/27,/28,/29,/30
Your Answer = /23,/24,/25,/26,/27,/28,/29,/30
Your answer is incorrect

code:
KiXtart
KiXtart Version = 4.21
KiXGolf Script = kixgolf_moan.kix

Computer
OS = Windows 2000 Professional
CPU = Intel Pentium III
Speed = 848 MHz
Memory = 512 MB

KiXGolf Scoring Engine
Scoring Engine = 3.0.3

KiXtart Golf Score
Tournament = KiXtart Golf: MOAN - Mother Of All Networks
Processing Start = 2003/05/26 21:33:00.937
Processing End = 2003/05/26 21:33:01.017
Duration = 0000/00/00 00:00:00.080
# Loops = 1
KiXGolf Result = failed (8 out of 9 correct)
KiXGolf Score = 868

Could we have a test for a subnetted class B too???

hoby, I started thinking the same thing...

then I came to the conclusion that there is actually more.
and then decided to go to bed [Big Grin]

why 255.255.252.0 would not be ok, dunno...

maybe there is this thing that 10 (as starting address) is impossible.

(10 & 252) equals 8 not 10 so 255.255.252.0 does not work as it changes the NetworkID.

I checked all possible subet mask values from at 8 bits to 31 bits and only the ones I list seem to be valid.

Hey! Time for a rollcall. Who is working on this KiXgolf problem beside Lonkero and me?

We seem to be the only takers here.

Damn those class A/B subnets. Can't get the subnetmask/ip-addresses to work... [Mad] [Mad]

Score for determining in-IPrange & NetWorkID = 530

Need an example / result list of determining the possible subnets for a class A/B subnet...

Anyone???

pat, that's about the score I had there too [Wink]

hoby, I must wonder...
if jens disabled that one as that 254 has only broadcast and network-id and thus the IP can't be there.

damn, this goes tricky... too tricky.

like jens already pointed out, my code broke more when tried to get this piece to work.
I think I'm gonna do total re-write... at least try as that method I figured when woke up and in the buss... it seems like zillion times shorter...
can't know though...

Howard, your calculations are correct.

IP address 10.10.10.2 and mask 255.255.254.0 would give you:
Subnet address: 10.10.10.0
Broadcast address: 10.10.11.255

All addresses in between are valid IP addresses, including 10.10.10.255 and 10.10.11.0

Jens, one question occurs to me. I can't see in the instructions where you are limiting the scope of the masks, so for a network of "10.10.10.0" you could apply a netmask of "10.10.10.255", which would be valid and give you a range of 168,430,336 potential addresses.

I assume that you are only using masks with contiguous bits.

I assumed continous valid subnet mask of 8 through 31 bits starting from the high order side (progressing from left to right).

Just to make it official, test 8 does have 255.255.254.0 or /23 as correct solution.

I've updated the .INI file accordingly. Download the package at http://people.bu.edu/jenmeyer/kixtart/kixgolf_moan.zip

quote:
I assume that you are only using masks with contiguous bits
Yes, that's correct. I believe you actually have to use contiguous bits as this is how CIDR is defined. See for example http://www.cisco.com/warp/public/701/3.html#cidr

I've also covered the 255.255.255.254 or /31 case where you only have two IP addresses, namely the network ID and the broadcast address. Quote from the rules in the Input&Output section:
quote:
Assumtion: Network/broadcast addresses are not available as regular IP addresses though RFC3021 allows /31 networks (two IP addresses where the network/broadcast addresses are used as regular IP addresses)

although, both cases can make the logic harder or easier, depending of the logic used.

Am here... Digging into my TCP/IP documentation.

Discovered my approach is a nogo for the subnets/ip-addresses... Must make redesign [Frown]

alright!
good to hear that I'm not only mixing ideas and codes [Wink]

think I need to do something to my script as only the isinsubnet-part (all parameters provided) is ready and it already has:
