How can I mask an IP address in JavaScript?


 Here is a function in JavaScript that takes an IP address as a string and masks all but the last octet:


This will output 192.168.1.x

This function uses the split() method to separate the IP address into an array of octets (i.e. ["192", "168", "1", "100"]), and the slice() method to select all but the last octet. It then uses the join() method to join the octets back together into a string, with the last octet replaced with "x".

The same question is asked in the following way but the answer for all is the same?

  • How can I make an IP address anonymized in JavaScript?
  • How can I mask all but the last octet of an IP address in JavaScript?
  • Is there a way to conceal parts of an IP address using JavaScript?
  • Can you provide an example of a JavaScript function that masks a given IP address?
  • How can I use JavaScript to obscure the first three octets of an IP address?
  • Is there any way to hide the IP address of a user in JavaScript?
