printer-level0.printers.coorp IN A 10.10.10.10
Not a problem in any sane DNS, not a problem for your issuer (who doesn't care about the IP) - though it could leak data outside. So to fix it, you could just solve the challenge in outside-facing DNS and only resolve the IP address if the request came from inside the corporate LAN.
Also, my school has so many IPs that they do give public IPv4 addresses to all machines, printers, etc. but block access with a firewall.
