Right now if I ping systemideveloper.com I get a bad IP of
69.25.27.170 - the response should be 216.109.205.50. Is there an
easy way of telling who is reporting the "bad" IP?

As it happens, I've been working on DNS stuff the last few weeks.

Using the nslookup command, you can set the server to lookup the domain in.

Set the server to each individual server that hosts your domain and lookup the domain on each.

I just did a nslookup and got a bunch of different answers.

systemideveloper.com has address 63.251.171.81
systemideveloper.com has address 66.150.161.140
systemideveloper.com has address 66.150.161.141
systemideveloper.com has address 69.25.27.170
systemideveloper.com has address 69.25.27.173
systemideveloper.com has address 216.109.205.50
systemideveloper.com has address 63.251.171.80

It looks like you have multiple IP's defined for the domain.

What's your primary DNS server?
