My domain is http://accountingpractitioner.com
This domain is hosted at Hostgator and was originally assigned assigned a shared IP address of 22.214.171.124/~kirkward
I was unable to register my API key using the IP address of 126.96.36.199
The API registration key page would not accept 188.8.131.52/~kirkward and I was unable to register the API key with that shared IP address.
Next, I upgraded my account to a dedicated IP address and was assigned an IP address of 184.108.40.206
When I attempted to register the API key with the IP of 220.127.116.11, I received an error message that I was trying to register from 18.104.22.168
So I attempted to use the IP address of 22.214.171.124, WPMUDEV gave an error message that I was attempting to register the API key from 126.96.36.199
When I attempted to register the API key from 188.8.131.52, WPMUDEV gave an error message that I was attempting to register the API key from 184.108.40.206
I was finally able to register the API key only after I entered both IP addresses with WPMUDEV. 220.127.116.11 and 18.104.22.168 were both required to be registered in order for the API key to work.
So, instead of having the ability to protect 5 sites with the API key, I may be limited to fewer.
Not a big deal in the grand scheme of things, but exposes a semi-defect in either the WPMUDEV Anti-Splog system or the Hostgator system. I don't know which.
Any suggestions on who should look at this?
