Google Gmail and Microsoft Hotmail and other web mail systems are refusing/bouncing mail from our new DHC instance. The problem is that we entered an AAAA record for the IPv6 address in our GoDaddy DNS zone and there is no PTR record for that address. We thought deleting the IPv6 address in our GoDaddy DNS zone file would correct the problem. That has not worked. Gmail, Hotmail, etc. are still bouncing due to no IPv6 PTR record.
Our thinking now is the best way to fix this is change our IP address on the instance. Then we update our IPv4 DNS records and the email should then go through. Since we are new to DHC, how do we change the IP address on a running instance?
Thank you in advance for your response.
