How to define REGEX to find IPs (even vs odd) in Smart Label

I am trying to create two smart labels and I am wanting to limit them to certain IPs. Either Even or Odd. The first three octets will vary. Could be 10.x.x.x or 192.x.x.x. I am just looking at the last digit of the last octet. We had this set up a long time ago, and then those disappeared so I am trying to recreate them.

Any thoughts? Need more information?

Ooo RegEx maths, I'm up for a challenge.

Try this for odds

\d{1,3}.\d{1,3}.\d{1,3}.\d*[13579]$


And this for evens

\d{1,3}.\d{1,3}.\d{1,3}.\d*[02468]$


Use this for testing sample data.

Even IP Smart Label
IP Address matches REGEX [0,2,4,6,8]$

Odd IP Smart Label
IP Address matches REGEX [1,3,5,7,9]$

Sorry for the delayed response. I didn't get a notification that I had responses to my question until today. Let me try these and report back. Thank you for the feedback. Will provide the results as soon as I can try them.

So I finally got the time to try this out and the good news is I got the desired results. Both of these solutions gave me the same information, but "flip1001" looked a little cleaner. Not saying what "rileyz" offered was wrong. I do wonder why the big difference between the two? Any thoughts on whether one has more applications than the other?
