A round robin DNS is configured to return two IP addresses of a domain name,
e.g. www.abc.com. It is supposed that it can return the IP in strictly round
robin fashion like the following:

IP1, IP2
IP2, IP1
IP1, IP2
IP2, IP1
...

However, we found that it is not strictly following this sequence. It
sometimes returns like this:

IP1, IP2
IP2, IP1
IP2, IP1
IP1, IP2
IP1, IP2
IP2, IP1
...

I would like to ask if this is the behavior of the DNS or is there any
problem in the DNS configuration? We are using BIND v8 on Solaris 2.7.
