I often have to generate a sequence of IP addresses so I created this simple online utility that does it for me. It lets you generate however many sequential IPv4 addresses you need from the given range. It works in the browser and is powered by alien technology from the future.

How Does This Ip Addresses Generator Work?
rangeEnd variables. There's also a
step variable that controls the distance between consecutive IP addresses. To create an output array of IPs, the program runs a
for loop with the initial expression
ip = rangeStart, condition expression
ip <= endRange, and increment expression
ip += step, and
ip value to array
ipList at each iteration step. When generating a specific count of IP addresses, the variables used are
step. In this case, the
ipList array is also populated via a regular
for loop with the counter
i going from
count. At each iteration step, the
startIp value is
pushed to the array and incremented by the
step value. As IP addresses consist of four decimal numbers (called octets), each between 0 and 255 and separated by dots, it's not easy to increment them directly. To make it easier to work with IPs, they are transformed from the dotted form
a.b.c.d to the single-integer form using the formula
intIp = aInt + bInt + cInt +dInt, where
aInt = a×256×256×256,
bInt = b×256×256,
cInt = c×256, and
dInt = d. After running the loop and filling the output array
ipList with IPs, they are converted back to the octet format through the reverse formula
(intIp>>24)&0xff + dot + (intIp>>16)&0xff + dot + (intIp>>8)&0xff + dot + intIp&0xff. The
dot variable can actually be any character and it can be changed in the octet separator option. The output IPs can also be converted to another base. In this case, the additional
BigNumber library is loaded. With this library, it's easy to convert each octet to a different base. First, each octet is converted into a big number by calling
new BigNumber(octet) and then it's converted to a string in the new base by calling
octet.toString(base). After all this, the IP addresses that were collected in the
ipList array are converted to plain text format by calling
ipList.join(ipSeparator) and are all printed to the output text box.
