Problem with resolution

I'm having trouble with the resolution of www.pncactivepay.com.  It
appears that most nameservers will resolve this host to 208.86.144.222.


Resolution for this host only works about half of the time, as shown by
my logs below.  When my resolvers are not able to get the real IP
(208.86.144.22), they get a bogus IP of 209.62.20.200.  It seems like
there is a misconfiguration on pnactivepay.com's side, but I'm not
certain.

Can anyone see an obvious problem?

$ host www.pncactivepay.com
www.pncactivepay.com has address 209.62.20.200

$ host www.pncactivepay.com
www.pncactivepay.com has address 209.62.20.200

$ host www.pncactivepay.com
www.pncactivepay.com has address 208.86.144.222

$ host www.pncactivepay.com
www.pncactivepay.com has address 209.62.20.200

5 minutes ago, I was not able to dig +trace this host, and it kept dying
at the 'J' root server.  Now, though, dig +trace seems to resolving the
host correctly.  There is still some inconsistency here, though.  Any
ideas?  Still, half of my "nslookups" and "hosts" are returning
209.62.20.200 for www.pnactivepay.com.  I have no idea where this
response is coming from.

$ dig +trace www.pncactivepay.com
