help with warnings and errors..

[Gianpaolo Corona]

Can anyone tell me how I can resolve the warnings mentioned below. After a dns check the check ended up with warnings mentioned below.
The refresh and expire I know what does mean but wat is "I zone and which A record" is missing    


      errors=2, warnings=3, informational=2 

      * domein interpay-test.nl. 

      * nameserver ns1.interpay.nl./82.195.51.55 

      W SOA refresh (2004062812) > 24 uur (zie RFC1537) 

      W SOA expire (864000) <= refresh (2004062812) 

      I zone heeft geen A records 

      E domein heeft geen MX of A record (TE.6d) 

      * extra nameservers 

      * nameserver ns2.interpay.nl./82.195.45.55 

      W SOA refresh (3600) < 4 uur (zie RFC1537) 

      I zone heeft geen A records 

      E domein heeft geen MX of A record (TE.6d) 


Thanks,

Gianpaolo
