What's keeping exchange.cootlogix.com from an A

exchange.cootlogix.com is an alias of rtb-gw-87g48sykgsr0k50oix5z45lun.990061196283.gateway.rtbfabric.us-east-1.amazonaws.com, which has no IPv6
exchange.cootlogix.com is a CNAME, so it can't also have its own AAAA record. Ask whoever runs rtb-gw-87g48sykgsr0k50oix5z45lun.990061196283.gateway.rtbfabric.us-east-1.amazonaws.com to enable IPv6 there — or replace the alias with the A and AAAA records they give you. Why some hosts don't offer IPv6
Mail servers without IPv6
Your domain's mail goes to its own address, which has no AAAA record.

What this means

Visitors on IPv6-only networks (many mobile carriers) can still reach it, but only through a translator their carrier runs (NAT64). The site itself has no IPv6 address — and you can't make one up from the IPv4. Why some hosts don't offer it
