What's keeping exchange.dsca.mil from an A

exchange.dsca.mil is an alias of ddsmttayz089.dsca.mil, which has no IPv6
exchange.dsca.mil is a CNAME, so it can't also have its own AAAA record. Ask whoever runs ddsmttayz089.dsca.mil 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.
Nameservers without IPv6
dns-pub-f1-u.pentagon.mil, dns-pub-f2-u.pentagon.mil, dns-pub-f3-u.pentagon.mil all have no AAAA record, so a resolver that only speaks IPv6 can't look your domain up. Most DNS providers offer IPv6 nameservers; ask yours, or move DNS to one that does.

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
