I think this is happening mostly for remote agents. I could care less about their IPV6 IP. I do care about their IPv4 IP :)

I'm guessing the Windows API is just passing along the first thing it finds.

Not a fix but a workaround for now:
You can run the command below using Send Command on these agents to get the IPv4 address.

nslookup myip.opendns.com. resolver1.opendns.com

I dug around and found where is is being done. No idea why because I dunno how to fix... except one idea.... remove ipv6 from icanhazip.tacticalrmm.io :)

I'm not sure how you tell go to prefer ipv4 over ipv6.

hi the icanhaz code is here xD https://github.com/wh1te909/icanhazip/blob/master/main.go i'll change it to prefer ipv4 and only return v6 if it's really using v6 and has no v4

I was thinking the change would be on the client. If it requests IPv6, then how can icanhaz know if it is dual stack ? Unless maybe you have the client do two requests? One for ipv4 and one ipv6.
