It's a browser issue.

They are adding in the rest of the URL. sandicor.com does not have an
A record. There is an A record for www.sandicor.com. Mozilla is doing
something behind your back.

Which is correct.

You mean a browser issue.

This is only a DNS issue in the sense that there's no A record for
sandicor.com.

To be truthful, you should be putting in the whole URL:
http://www.sandicor.com/ and not expect the brower to add things
for you.

Add an A record to the the root of the zone:
@       IN      A       66.237.32.36
www     IN      CNAME   @
and remove the old www record, update the SOA serial number and reload
the zone.
