How to extract IPs from a given string

[skumar_srbh]

Hi Team...

I have a case where, expected to extract all the IP addresses from a given input.  I did use few regex , but it does not work completely. could anyone please suggest a valid regex which will work for the below scenarios as well.. 

i/p  -

"This 1.1.1.1 is an input2.2.2.2,to extract all the IP address [3.3.3.3], which 44.4.4.4regex should be used 3.3.3.P to extract all the valid IP address."

expected  o/p - 1.1.1.1 ,  2.2.2.2, 3.3.3.3 , 44.4.4.4

Thanks in advance for the help!!!

What will be an expected input? can you share that. There should be some common pattern to extract the same.

sample input

"This 1.1.1.1 is an input2.2.2.2,to extract all the IP address [3.3.3.3], which 44.4.4.4regex should be used 3.3.3.P to extract all the valid IP address."

@skumar_srbh we usually do string manipulations to get substring but in your case it does not follow any pattern.

Hi, please try this regex

var str1 = "This 1.1.1.1 is an input2.2.2.2,to extract all the IP address [3.3.3.3], which 44.4.4.4regex should be used 3.3.3.P to extract all the valid IP address.;";
var str2 = str1.match(/\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}/g).join(", ");
gs.info('The list of IP addresses: '+str2);
