Thanks for help.
I was wondering if HMAC* keys are not used for zone then why the same is
displayed when we use "dnssec-keygen -h".

Zone keys are used for DNSSEC signing zones.
Host keys are used for TSIG transaction authentication, for securing zone
transfers or dynamic updates.

Your security is affected more by how you store the keys than anything else.
RSASHA256 is fine.
