DNS based load-balancing on VPNs

Hello folks, I'm stuck on a problem that I don't know what to do.

​

I have 2 ASAs at Site A in Active/Standby. I have 2 more ASAs at Site B in Active/Standby. These 2 sites are identical so no matter which site you connect to, you can do your job just fine. I was wondering is their any way of doing DNS load-balancing? So I just want site A and site B to take in equal connections instead of everyone just going to site A all the time. Does anyone have a setup like this?

​

For example:

site A IP address 1.1.1.1 - vpn.xyz.com

site B IP address 2.2.2.2 - vpn.xyz.com

So I would have the same A record, but pointing to 2 different public IPs. is this possible?

​

is there any way to Load-balance that through our external DNS provider?
