Proxy Listing

Hi Dot com, I have a question: I was doing the very first node and the netmask returned:

netmask 12.173.164.0-12.173.164.255
12.173.164.0/255.255.255.0	12.173.164.0/0.0.0.255	12.173.164.0/ 24

I had to double check, but I indeed typed in the correct range. When following the example, the IP range without the netmask makes no sense. With the netmask it makes a little bit more sense but it still makes no sense. So... a) is this correct? b) do you guys need the netmask? c) if this affects other wiki's are there other groups doing the same thing? Are they "inter-collaborating"? --Stux 03:58, 16 November 2005 (UTC)

What doesn't make sense about it? Looks fine to me. The netmask is unnecessary, as it's implied by the /24. --Jay (Gobble) 04:00, 16 November 2005 (UTC)

Maybe my terminology was incorrect, but the part we need is 12.173.164.0/ 24, with the slash and the two-digit number. — It's dot com 04:04, 16 November 2005 (UTC)

Edit Conflict Yeah but the range is from 12.173.164.0-12.173.164.0 implying one IP address? I am not too familiar with the last two notations: 12.173.164.0/0.0.0.255 and 12.173.164.0/ 24 and I wanna make sure i'm not missing anything. --Stux 04:05, 16 November 2005 (UTC)

I'm not totally sure what the first two numbers and masks mean, but what we're looking for is the last one, the one bolded above. — It's dot com 04:07, 16 November 2005 (UTC)

The mask is supposed to be a logical AND of the binary representation of the numbers, the first will return only the first 3 numbers, and the second only the 4th number. --Stux 04:09, 16 November 2005 (UTC)

Edit Conflict See Lapper seems to be getting different numbers: 12.173.164.0 || 12.173.164.255 is what he's (what seems to me correctly) reporting. --Stux 04:08, 16 November 2005 (UTC)

Also edit conflict'd The mask stuff (255.255.255.0, etc.) isn't important here. The actual range is the part where it says "12.173.164.0-12.173.164.255". What the /24 terminology means is that 24 bits remain the same in all addresses in the range. Each part of an IP address has eight bits, so this means that the first three parts will be the same for all addresses. The last eight bits (the entire fourth part) can be anything - but no part in an IP address can be larger than 255 (the largest number possible with eight bits.) If it was, say, /25 (and the fourth part was still zero) then only 7 bits could change, so the range would be 12.173.164.0-12.173.164.127, for instance. (This makes a lot more sense if you've taken several years of computer science, lemme tell ya.) --Jay (Gobble) 04:11, 16 November 2005 (UTC)

Makes perfect sense, but again if you notice, the netmask calculator isn't giving me a 0-255 range it's giving me a 0-0 range. That's what I want to clarify. --Stux 04:14, 16 November 2005 (UTC)

Different format

Hey what about these... which number do you want? I am assuming that the range you want is 61.197.218.176 - 61.197.218.183.--Stux 04:12, 16 November 2005 (UTC)

Yes, that's right. — It's dot com 04:14, 16 November 2005 (UTC)
