D toc

 

Excerpt

Computes a four-octet internet protocol (IP) address from a 32-bit integer input.

Source value must be a valid integer within the range specified by the formula below. A valid IPv4 address is in the following format:

Code Block
aaa.bbb.ccc.ddd
Info

NOTE: IPv6 addresses are not supported.

The formula used to compute the integer equivalent of an IP address is the following:

(aaa * 2563) + (bbb * 2562) + (ccc * 256) + (ddd) 

So, the formula to compute this IP address is the following:

Inputaaabbbcccddd
X

aaa = floor(Input / (256 3 ))

remainderA = Input - aaa

bbb = floor(remainderA / (256 2 ))

remainderB = remainderA - bbb

ccc = floor(remainderB / 256)

remainderC = remainderB - ccc

ddd = remainderC

Output value:

Output = aaa + '.' + bbb + '.' + ccc + '.' + ddd

WrangleTextderive type:single value: ipfromint('16909060') as:'ip_addr'

ipfromint('16909060')

Output: Returns the IP address 1.2.3.4

Column reference example:

ipfromint(IpInt)

Output: Returns the values of the IpInt column converted to an IP address value.
