Currently it's on the dev branch. It's not a consensus change and it's an optional feature that defaults to OFF. Probably a good idea to put it in the upcoming 3.5.0 mandatory release.

It improves defenses against attacks where malicious nodes spawn up in different Class B IP address ranges, by tracking Autonomous System Numbers (ASNs).

This was originally done in BTC and ported to KMD by Decker:

This is not ready for 3.5.0, hopefully it will be in our next release. Seems like it is still undergoing testing in KMD as well
