According to Terry Soucy:

The problem is that dns.integrant.ca is a CNAME and not an A record.

dns.integrant.ca.       86400   IN      CNAME   integrant.ca.
integrant.ca.           86400   IN      A

According to the standards, an NS must point to an A RR. Most
recent dns (and thus bind) versions adhere to the standards and
thus will not resolve the domain. Older implementations sometimes
follow the CNAME.
