Hello! I have a problem to report: in the northeast region of Brazil, nextdns has 2 low-latency servers located in Fortaleza, CE. The problem is that the server configured for IPv4 has a latency below 25ms, in IPv6 it is giving 50ms more latency.

 Would you be able to fix this or is it something that is out of your reach and restricted to my ISP? Thanks in advance!
