IPv6 readiness

Publishes IPv6 but doesn't answer on it — worse than having none.

What's keeping rocksecurityservice.com from an A

Fix or remove the AAAA record for rocksecurityservice.com
Something published an IPv6 address but nothing answers on it, so IPv6 visitors wait for a timeout first. Either make the server listen on IPv6 (and allow ports 443/80 through its firewall), or delete the AAAA record until it does.
Mail servers without IPv6
mx.stackmail.com has no AAAA record, so mail from IPv6-only servers can't reach it directly. If a provider runs your mail, that's their setting; if you run it, add AAAA records for these hosts.
Nameservers without IPv6
ns3.serverbyt.in, ns2.serverbyt.in, ns4.serverbyt.in, ns1.serverbyt.in 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.
