Those are A class IP addresses. D class are 224.0.0.0 to 239.255.255.255 if I'm right, and those ones are not used often. May I ask why you want a lot of IP addresses when you don't even know the difference between them?
wikipedia "IP Classes" Those are class A....usually like...residental computer IPs 0.0.0.0-127.255.255.255 Class D - E aren't even public domain I believe...your friend is a silly ninny The list you got is terrible...PM me if you want to work something out
I can't edit my post...blah...but I need to add that those IPs were bloody port sniffed...and that is insanely frowned upon by host and ISP...Whoever you got that list from was like sniffing some neighborhood...what a tool ....especially considering none of the IPs have ports on them... an IP 0.0.0.0 without 0.0.0.0:0 is essentially someone saying "here, ping my IP 99999 times"
ha ha ha . its a very interesting chapter. ..........yes these are c class ips . not A class. how A class or B? proof?. you all don't know about these ips . can you please explain what is A class and B and C.........................................? I am in Canada and this is my special field and i got MS degree close to this, I already been work in hosting company for 9 years i understand this kind of cases usually receiving queries to hosting companies by their clients who are not aware by the network . i replied many answers related to ips to the clients across the globe but its very difficult to understand by a new client, only hosting companies can guide you bitterly. you people have to learn first about ips then post the comments. let me teach you first what is ip and how we see IP addresses. i will come again in this forum to teach you further if i could get time from my job as i am handling IT Inter Exchange network of a communication company in Canada. Lets start the 1st class today: How we see IP addresses An IP address is numbers that represent a device on a network, as a mailing address represents your home's location. But in order to actually assign and use IP addresses, you must understand the format of these "numerical identifiers" and the rules that pertain to them. Let's first concentrate on how humans read and write IP addresses. To us, an IP address appears as four decimal numbers separated by periods. For example, you might use 204.132.40.155 as an IP for some device in your network. You might have noticed that the four numbers making up an IP are always between 0 to 255. Have you ever wondered why? You may also have heard people referring to each of the four numerical values in an IP address as "octets". Octet is, in fact, the correct term for describing the four individual numbers that make up an IP address. But doesn't it seem odd that a word whose root means "eight" describes a number from 0 to 255? What does "eight" have to do with those values? To understand the answers to these questions, you have to look at an IP address from your computer's viewpoint. Computers think in binary Computers see everything in terms of binary. In binary systems, everything is described using two values or states: on or off, true or false, yes or no, 1 or 0. A light switch could be regarded as a binary system, since it is always either on or off. As complex as they may seem, on a conceptual level computers are nothing more than boxes full of millions of "light switches." Each of the switches in a computer is called a bit, short for binary digit. A computer can turn each bit either on or off. Your computer likes to describe on as 1 and off as 0. By itself, a single bit is kind of useless, as it can only represent one of two things. Imagine if you could only count using either zero or one. Alone, you could never count past one. On the other hand, if you got a bunch of buddies together who could also count using zero or one and you added all your buddies' ones together, your group of buddies could count as high as they wanted, dependent only on how many friends you had. Computers work in the same way. By arranging bits in groups, the computer is able to describe more complex ideas than just on or off. The most common arrangement of bits in a group is called a byte, which is a group of eight bits. Binary arithmetic The act of creating large numbers from groups of binary units or bits is called binary arithmetic. Learning binary arithmetic helps you understand how your computer sees IPs (or any numbers greater than one). In binary arithmetic, each bit within a group represents a power of two. Specifically, the first bit in a group represents 20 [Editor's note for non-math majors: mathematicians stipulate that any number raised to the power of zero equals 1], the second bit represents 21, the third bit represents 22, and so on. It's easy to understand binary because each successive bit in a group is exactly twice the value of the previous bit. The following table represents the value for each bit in a byte (remember, a byte is 8 bits). In binary math, the values for the bits ascend from right to left, just as in the decimal system you're accustomed to: 8th bit 7th bit 6th bit 5th bit 4th bit 3rd bit 2nd bit 1st bit 128 (27) 64 (26) 32 (25) 16 (24) 8 (23) 4 (22) 2 (21) 1 (20) Now that we know how to calculate the value for each bit in a byte, creating large numbers in binary is simply a matter of turning on certain bits and then adding together the values of those bits. So what does an 8-bit binary number like 01101110 represent? The following table dissects this number. Remember, a computer uses 1 to signify "on" and 0 to signify "off": 128 (27) 64 (26) 32 (25) 16 (24) 8 (23) 4 (22) 2 (21) 1 (20) 0 1 1 0 1 1 1 0 In the table above, you can see that the bits with the values 64, 32, 8, 4 and 2 are all turned on. As mentioned before, calculating the value of a binary number means totaling all the values for the "on" bits. So for the binary value in the table, 01101110, we add together 64+32+8+4+2 to get the number 110. Binary arithmetic is pretty easy once you know what's going on. How computers see IP addresses So now that you understand a bit about binary (pun intended), you can understand the technical definition of an IP address. To your computer, an IP address is a 32-bit number subdivided into four bytes. Remember the example of an IP above, 204.132.40.155? Using binary arithmetic, we can convert that IP address to its binary equivalent. This is how your computer sees that IP: 11001100.10000100.00101000.10011011 Understanding binary also provides you with some of the rules pertaining to IPs. We wondered why the four segments of an IP were called octets. Well, now that you know that each octet is actually a byte, or eight bits, it makes a lot more sense to call it an octet. And remember how the values for each octet in an IP were within the range of 0 to 255, but we didn't know why? Using binary arithmetic, it's easy to calculate the highest number that a byte can represent. If you turn on all the bits in a byte (11111111) and then convert that byte to a decimal number (128 + 64 + 32 + 16 + 8 + 4 + 2 + 1), those bits total 255.
