Unfortunately, I don't have a list of specific vendors. I know that some vendors like to have the EZproxy server IP address since that tends to get the most traffic. Vendors know not to block that IP address for high traffic.</div>

We have over 20 locations and need to update IP addresses about once a year due to Google Fiber changes. I have an email group for those vendors not on the IP registry. You might want to let all of your vendors know just in case.</div>

Hi, all!</div>

We're planning to change our Ezproxy server's IP address on Monday Jan 26 to a different address still within the same range as the rest of campus.</div>

</div>
<div class="x_elementToProof" style="font-family:Calibri,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
We are registered with theipregistry.org and I will change it there, but not all of our vendors use that service.</div>

<br>
</div>
<div class="x_elementToProof" style="font-family:Calibri,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
Most vendors are happy with the proxy server being in the overall campus range and won't care that we change ezproxy's IP address in particular as long as it's within our campus range they already know.</div>

So I am concerned about identifying which vendors meet both of these conditions:</div>

</li><li style="font-family:Calibri,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
<div role="presentation" class="x_elementToProof">they will NOT get that information from theipregistry.org</div>

If any of you can identify those vendors, it would help us a lot, thank you!</div>
